The Risky Business of Lifestyle Genetic Testing: Protecting Against Harmful Disclosure of Genetic Information
Gabrielle Kohlmeier*

Introduction

The perfect gift for the genetic age. Testing of your unique DNA is now available, easy to do, and usable. For the first time, advanced genetic tests can be ordered together at great savings.

People can now order nutritional, ancestry and drug reaction DNA tests without going to their doctor, most samples can be collected at home using a cotton cheek swab.

LEAD A BETTER LIFE BY LEARNING ABOUT YOUR INDIVIDUAL DNA MAKEUP.1

[¶1] Nutrigenetics - the "newly developing science of how a person's diet interacts with his or her genotype to influence the balance between health and disease"2 - promises an easier way to escape the consequences of unhealthy lifestyles. The technological and scientific advances of nutrigenetic testing imply that the future is here, but unfortunately the legal protections are not. This deficit of legal safeguards leaves anybody who wants to take advantage of the potential of nutrigenetics vulnerable to considerable risks, including psychological harms and identity crises caused by a misunderstanding of, or unwanted exposure to, genetic information, stigma and discrimination arising from harmful third-party release of the genetic information, and violation of privacy, equal protection, and potentially even loss of property interests.

[¶2] Yet with more than half of Americans classified as overweight or obese3 - many of whom face incentives or even pressures from employers or insurance companies to improve their health and diet - it is no longer just a fringe of health conscious Americans seeking high-tech solutions. Many of those same people - both those who are already facing health problems and those seeking to avoid them - are among the majority of American consumers who prefer self-treatment options to seeing a doctor.4 The "perfect gift for the genetic age" that genetic testing purportedly offers thus captures a large and receptive audience, particularly given its promises of "[s]elf knowledge [that] leads to self empowerment and self improvement."5 Under the heading "Nutritional Genetics: Personalized Nutritional and Lifestyle Recommendations from the Genetic Age," the benefits one may expect are said to include:

Reduced cravings caused by nutrients missing from your diet.
Optimize the health and durability of your skin, hair and bones.
Harmonize your diet and life-style with your genome by learning about genetically related risk factors to the big three diseases-heart disease, cancer, and diabetes, that your diet can influence.
Easier compliance with your self-improvement program because personalized advice lets you know that what you are doing is based on your unique needs and will be effective.6

[¶3] Most importantly, this nutrigenetic report promises "[a]dvice that lasts a lifetime because your genes are not a fad."7 Although the lofty promises offered sound much like a dramatization or hypothetical scenario, the quoted text comes from a website currently offering nutrigenetic testing.8 What the website does not disclose are the myriad problems-including legal problems-potentially posed by ordering this information that will likely last a lifetime.

[¶4] The enthusiasm for nutrigenetics may obfuscate the unusual problems surrounding protection of genetic information particularly in a market context. The gravest concern is one of control-upon providing genetic material for lifestyle genetic testing, an individual has little command over who has access to the results. And unregulated access can have devastating effects. Even if the raw genetic information merely is sent back directly to the individual, serious misinterpretation concerns arise due to lack of counseling; in extreme cases, for example, individuals have interpreted genetic information as a death sentence leading to severe psychological trauma and even suicide. Perhaps even more alarming is the release of the genetic test results or genetic materials to third parties to whom the individual never intended to impart the information or material. Release of genetic information to unknown third parties may be a path fraught with peril. The ramifications of such third-party release not only raises considerable liberty concerns-from privacy and equal protection to perhaps even property rights issues, but can also result in significant damage that cannot be undone, such as stigma and discrimination not only against the customer but all the blood relatives who carry some of the same DNA.

[¶5] Current regulations and safeguards inadequately address the significant legal problems posed even by accurate genetic information, because they fail to sufficiently consider who may obtain the information, including the bearers of the genetic information themselves. To better protect genetic information, courts should recognize an individual's right to control personal genetic information, and Congress should expand existing and proposed legislation to protect information obtained through nutrigenetic and other lifestyle genetic testing. Such legislation should incorporate nutrigenetic and other nonpathologic9 testing within its scope and mandate safeguards preventing the numerous legal problems raised, but also allow relevant information to be obtained by individuals and individually authorized third parties. A double-masking system, which separates the raw genetic data from derived information before passing it on to consumers, can achieve this by supporting individuals' rights to control access to genetic information while also protecting individuals from unwanted, potentially harmful information.

[¶6] This Article starts by surveying the current environment of genetic testing. Following a brief description of nutrigenetics, Part I provides a broad picture of the conditions bolstering the imminent rise of nutrigenetics, and then focuses on the current environment of genetic testing. These macro- and micro-snapshots contrast the various benefits and dangers of nutrigenetics in a currently inadequate regulatory and statutory regime. Part II explains why nutrigenetic testing poses even greater risks than traditional pathologic genetic testing, focusing on the difference in both the scope of testing and the change of setting in which nutrigenetics takes place-a marketplace rather than a doctor's office. Part III briefly overviews traditional problems posed by the disclosure of inaccurate information and highlights unique problems associated with the disclosure of accurate genetic information. Part IV considers the key issue of who should (or should not) have access to and control over genetic information. This analysis focuses primarily on the legal (and to a lesser extent medical) problems of providing genetic information to individuals and other interested parties, as well as the legal problems of not allowing them access.

[¶7] Against this backdrop, Part V examines and illuminates the deficiencies of previous proposals, legislative and regulatory efforts to protect genetic information, and pending congressional legislation. Juxtaposed against these shortcomings, Part VI describes the benefits of a double-masking model, emphasizing the need to separate the information derived from genetic information from the genetic information itself. Finally, this Part sets forth statutory provisions that Congress should pass to protect genetic information.

Weighty Problems Open the Door for Nutrigenetics' Popularity

[¶8] The last two decades gave rise to exponential increases in the number of obese and overweight individuals around the world, and particularly in the United States.10 Indeed, the obesity epidemic is expected to result in more than fifty percent of the U.S. population being classified as obese by 2020.11 In addition to individual health consequences, the individual and aggregate economic effects are already significant. Medical costs, for example, continue to rise in the face of expensive treatments that ameliorate, but do not cure, obesity-related diseases.12 As the costs are only expected to rise, government spending projections forecast an enormous proportion devoted to health care.13

[¶9] Against this background, nutrigenetics provides a beacon of hope. The ultimate goal of nutrigenetics is to provide personally tailored dietary and lifestyle recommendations based on an individual's genetic makeup. This holds tremendous promise for individuals seeking to improve the quality of their lives, and offers a remedy to employers, insurers, and governments facing the tremendous negative economic effects of the obesity epidemic and soaring health care costs.14 At the same time, commercial entities are eager to exploit the nutrigenetics market.15 What makes nutrigenetics particularly attractive to businesses is the apparent lack of built-in market limitations.16 Before delving further into what distinguishes nutrigenetics from other types of genetic testing, however, it is important broadly to understand genetic testing.

Introduction to Genetic Testing

[¶10] Genetic testing involves examining deoxyribonucleic acid (DNA) from an individual's blood, tissues, or bodily fluids for variations in the individual's genes.17 Although scientists initially believed that one gene regulated one particular function (or dysfunction) scientific advances have shed light on this oversimplification.18 Scientific understanding has evolved to recognize that one gene can code for multiple proteins, and multiple genes can affect coding of a single protein. In other words, single genetic variances may affect more than one condition, and for many conditions, more than one gene plays a role.19 For years, genetic testing has involved diagnostic, screening, and predictive tests looking for disease.20 Nonpathologic testing, however, is now becoming increasingly available, and expectations of future demand for such nonpathologic tests are high.21 Nutrigenetic testing is an emerging area of nonpathologic genetic testing that looks at the influence of interactions between diet and genotypes on health and disease.22

[¶11] Pathologic and nonpathologic testing hold opportunities for improving quality of life, and for providing economic benefits both to individuals and society at large. These tests also pose numerous legal and other dangers that are inadequately addressed by the current regulatory and statutory regime. A passing familiarity with the state of the genetic testing industry illuminates these dangers.

[¶12] The market for genetic testing is increasing at a rate of thirty percent annually.23 At the same time, the number of genes being tested is increasing exponentially.24 Though the tests are evolving and the market expanding, the form of transmitted information generally remains the same. Clients are provided either the raw genetic information-the particular genetic variants accompanied with a brief global summary explaining what the genetic information means, or the derived genetic information, which consists of only the meaning of genetic information, and not the specific genetic variants. Derived information provides only the specific information the person sought, whereas raw genetic information reveals the genetic variation, which is interpreted to extract the information sought. For example, if a person requests a genetic test to find out whether her bone health might be compromised, the derived genetic information would simply indicate an increased need for vitamin D. The raw genetic information, by contrast, would be that she carries the taq1 variation of the VDR gene, which implies not only the higher vitamin D requirement but also possibly an increased risk of osteoporosis, cancer and other dire health conditions. Current practice is to provide the individual with such raw genetic information.25 The distinction between raw and derived genetic information is critical because the significant problems resulting from disclosure-particularly of nutrigenetic test information-primarily arise in the context of raw genetic information, and would be significantly mitigated by disclosing only derived genetic information.

Nutrigenetics: Super-Sized, with Drive-Through Ease

[¶13] The scope and context of nutrigenetics heightens the risk of information disclosure. First, nutrigenetic testing evaluates a much greater range of variations than traditional pathologic testing. In the context of diseases, genetic testing is generally narrow because patients go to their healthcare provider with a very specific inquiry. In the narrowest cases, for example, patients may want to know whether they have the specific genetic variant for Huntington's disease or inherited forms of BRCA, the breast cancer gene. In broader cases, a patient may seek genetic testing to explain multiple miscarriages, in which case the healthcare provider may order a menu of tests to examine the various different genetic variations related to fertility or pregnancy problems. Even in the latter case, however, the number of specific variations examined is still quite small.26

[¶14] Nutrigenetics is considerably different. Nutrigenetic tests do not seek any single or handful of genetic variants; instead, these tests look for a large number of different variations that appear to interact with diet and lifestyle. Thus, the test itself is exponentially broader. Testing for more variations is also becoming cheaper, particularly as the capacity to do so increases exponentially. Accordingly, testing companies already have incentives to create broad, multipurpose tests that analyze thousands of genetic variations. The testing companies would then filter out the information relevant to the particular test and pass it on to the individual.27 This is easier than creating a different test depending on the individual profile, or even creating different tests for subgroups based on age and sex, where entirely different genetic variations are relevant.28 The enormously larger dimensions of these tests therefore mean that there is much more genetic information at play in the context of nutrigenetic testing.29

[¶15] Second, nutrigenetics changes the context of genetic testing dramatically. Pathologic genetic testing looking for Alzheimer's disease, breast cancer, or prenatal diagnostics for Down Syndrome are firmly grounded in the medical context, which provides a structured framework. Prior to testing, patients go to their doctor's office or to a genetic counselor, where the trained practitioner advises them of the risks, implications, and meaning of tests. The health professional can also highlight limitations of the tests and explain why the patient may not want to undergo the test. If the patient chooses to proceed, the professional obtains consent and sends the patient's specimen to federally certified laboratories. The doctor then receives a test report with the genetic variations and often a global interpretation (essentially a short summary saying that these results point to a specific probability of the tested disease or condition, for example). The patient returns for an intensive, detail-oriented session, where the professional explains the findings of the tests and the risks of proceeding based on this information. If patients insist, they will be given a copy of the report with the raw genetic information and the global evaluation.

[¶16] Nutrigenetics radically shifts the context from a supportive healthcare environment to the commercial marketplace,30 thereby turning the patient into a consumer acquiring the information from profit-driven direct-to-consumer services.31 The likelihood of information being inaccurate may increase substantially in the commercial context, as it is unclear whether many of the regulations currently covering genetic testing even apply in this situation.32 Motivated by the prospect of profit, the incentive for these commercial entities to offer questionable or unproven tests is high.33 In fact, the Government Accountability Office (GAO) has already exposed numerous websites offering nutrigenetic testing as scams based on the inaccurate information they provided.34

[¶17] This contextual change further amplifies the dangers present even when results are accurate. People already treat nutritional and lifestyle decisions more casually than more concrete medical decisions, such as testing for genetic diseases or prenatal testing. Recommendations concerning how much coffee to drink are not considered life altering to the same extent as finding out whether one has the genetic variation for Huntington's disease, or whether one's fetus has Down Syndrome. The marketplace setting further diminishes the weightiness of the decision. You just swab a cotton stick in your mouth, put it in an envelope, and wait to hear whether you should stay away from coffee.35 There is no pre-test counseling to explain the implications and limitations of the test, or personalized explanation of why you may not want to have the testing done. On the contrary; the commercial testing services have incentive to hype their test to persuade the consumer to buy it.36

[¶18] After convincing the consumer to order the test, and analyzing the genetic material received, the testing service sends the test results directly to the consumer. As one nutrigenetic service explains: "Once your diet, lifestyle and genes have been analyzed, we'll send you a confidential personalized Action Plan telling you how to match your diet and lifestyle to your genes."37 This report includes a "health profile" providing the raw genetic information.38 A sample table provided by one website lists the genes analyzed, their role in a particular health function, the particular genetic variation screened for, whether the variation was found in this particular individual's gene, the percentage of the population that has the genetic variation, and then answers yes or no to whether the result suggests an impact on bone health.39

[¶19] Thus, the individual receives a lengthy report listing many genetic variations. Although the genetic variations may only be linked to certain health issues at present, media reports describe almost daily advances indicating new correlations between genetic variants and innumerable conditions. An individual, hearing about such a new finding, could easily check whether the nutrigenetic report they have received lists a variant mentioned in the media report.40

[¶20] Based on the ostensibly innocuous nature of the information sought, in combination with the ease with which such information may be obtained, individuals are more likely to seek direct genetic testing for nutrigenetic purposes than for pharmacogenomic41 or pathologic genetic testing.42 In this context, then, the heightened need to control access to this information becomes plain.

Even If It's Right, It May Be Wrong: Problems of Disclosing Inaccurate and Accurate Genetic Information

[¶21] When information is a commercial product, concerns that the information may be inaccurate naturally arise, and governmental regulations generally focus on this concern. The ultimate goal of regulators is to make sure that information is accurate – that there is no fraud, misrepresentation, or product defect. Genetic testing, including nutrigenetic testing, is no exception. What differentiates it from other testing, however, are the significant problems posed by accurate genetic information.43

[¶22] Even if regulators could ensure that information generated by genetic tests is accurate, concerns arise that are perhaps even greater than those relating to inaccurate information. Thus, different protections are needed than those sufficing for other types of products. To more sharply highlight the distinctive problems arising in the context of genetic (including nutrigenetic) testing, this part therefore separates the issues into (1) typical problems of inaccurate information and (2) the unique problem of accurate information.44

Inaccurate Information Problems

[¶23] A defective product is one that cannot be used for the purposes intended, or is made dangerous as a result of a flaw or imperfection. Information inaccuracy in the context of genetic testing is a type of product defect, where the inaccuracy itself is the problem. Inaccuracy couched in false promises of accuracy defrauds consumers.45 Furthermore, inaccurate genetic information raises serious safety concerns.46 It may lead to misdiagnoses and inappropriate recommendations with considerable health implications.47 As one recent report explained, "an inaccurate test result can lead to ill-informed decisions with tragic consequences, and to wasted healthcare resources."48 At this nascent stage, the primary concerns regarding nutrigenetics are that the genetic tests provide evaluations and recommendations that are so vague as to be virtually worthless.49

[¶24] Genetic information inaccuracies arise for various reasons, including poor quality control of the tests themselves, inadequate scientific evidence supporting the tests,50 and outright scams.51 Numerous safeguards work to mitigate these problems in the context of pathologic genetic testing. Those tests are generally performed in a doctor's office, allowing the physicians to serve as one layer of protection. Because usually just one (or very few) genetic variants are assessed, the health professionals administering the tests are generally more knowledgeable as to the level of confidence one should have in these findings. The laboratories doing this type of testing are subject to federal regulations,52 which afford assurances of analytical validity for the limited number of analyzed markers, thereby offering a certain degree of protection to ensure that tests are reliable. Moreover, the discussion spurred by the Human Genome Project53 about genetic information concerns focused attention and academic discussion on pathologic genetic testing, thereby providing another layer of protection.

[¶25] Nutrigenetics differs significantly because of its commercial context and the more casual atmosphere in which information transfer occurs. This may convey the false impression that nutrigenetic testing is a relatively trivial undertaking. Additionally, the number of genetic variants assessed increases dramatically compared to traditional pathologic testing, as the exponentially larger volume strains already tight oversight resources and requires experts to become proficient in not just a hundred or so genetic variants, but hundreds of thousands. At the same time, online testing of any sort largely removes the safeguard previously provided by the interaction with a healthcare professional.54

Accurate Information Problems

[¶26] Unlike the situation concerning inaccuracy, accurate information itself is not the problem. Rather, accurate information is hazardous in that it gives rise to other problems, specifically those of misinterpretation, self-overdisclosure, and harmful third party disclosure.

[¶27] Misinterpretation includes both misperceptions and misunderstandings of what the data means, even if the data are accurate. Genetic determinism, the idea that what is written in your genes is an inevitable and inescapable fate, is one of the most deleterious forms of misunderstandings.55 Genetic determinism can, on one hand, give people the incorrect idea that because they do not have a particular gene, they have carte blanche and need not make conscientious lifestyle choices. On the other hand, genetic determinism may lead people with a particular genetic variant to see disease manifestation as inevitable, even though it may never occur. Unfortunately, the reports about genetics in the media and in popular culture have strongly reinforced this fallacious notion of genetic determinism.56 Lack of adequate counseling by a licensed health professional further heightens the danger of individuals being misled, or misinterpreting what test results mean. Yet the direct-to-consumer nutrigenetic testing often does not ensure such counseling.57

[¶28] Further problems manifest when an individual receives more information than they bargained for or wanted. Individuals receiving unwanted or potentially harmful excess information can be termed "self-overdisclosure." In the context of genetics, self-overdisclosure is significant because the information can gain additional meaning as scientific developments progress. Additional meaning denotes not only greater understanding of the connection between a genetic variant and the tested-for condition, but even more importantly, new correlations between the same genetic variant and other, unrelated conditions-including pathologic conditions. For example, in the early 1980s, researchers testing for APO-E (thought to correlate innocuously to blood cholesterol levels) disclosed to the patients the rare gene they possessed. Shortly thereafter, it was found that APOE is also a predictor for Alzheimer's disease.58

[¶29] Finally, even if an individual properly understands the genetic test results or gets only the bargained-for results, unauthorized or unanticipated third party disclosure still poses problems.59 Particularly in the context of nutrigenetic testing, even third party disclosure that is not illicit can have detrimental effects further down the line. Discrimination against the individual-for example, by employers, insurance companies, or family members-is one of the greatest concerns.60 Although the same troubles arise in the context of inaccurate information, the point is that these problems persist even if inaccuracy is eliminated. In fact, a higher degree of confidence that the information is accurate may actually exacerbate the prevalence of genetic discrimination, as well as the problems associated with misinterpretation.61

[¶30] The difference between accurate and inaccurate information is not merely semantic; recognizing the difference between accurate and inaccurate information is critical to legislative and judicial efforts to protect individuals' autonomy and genetic privacy because the legislative and regulatory responses differ based on the type of information involved. As shall be illustrated, the current legal protections for genetic information are incoherent, at least in part because of the different approaches to accurate versus inaccurate information.

Comparing Approaches to Accurate and Inaccurate Information

[¶31] Inaccurate information problems are the traditional purview of regulatory agencies, such as the Federal Trade Commission (FTC) and the Food & Drug Administration (FDA).62 For inaccurate information, the problem exists instantly-something went wrong before the consumer even received the information; the product itself was defective. Although still insufficient, approaches to inaccurate information take the form of statutory requirements and practical efforts by federal agencies focused on addressing these instantaneous inaccurate information problems.

[¶32] Approaches to preventing accurate information problems, including misinterpretation, third party disclosure, and self-overdisclosure, are less concrete both in terms of their enforceability and applicability. Ethical guidelines of medical associations, which are not legally binding and not applicable to commercial services,63 comprise much of the extant protections. One explanation for the lack of concrete regulation and legislation is that the problems of accurate information disclosure are themselves significantly more remote and abstract than inaccurate information problems. Even if genetic information gets out to third parties, the effects may not be immediately apparent or even immediately harmful-the harm may not actually occur until some remote point in the future, for example, when the information is the basis for discrimination.64

[¶33] Furthermore, unlike the concrete product defect that inaccurate information represents, the precise violation regarding accurate information is more nebulous. For example, although it would appear that unwarranted disclosure of accurate genetic information implicates loss of privacy, continuing debates over whether genetic information implicates privacy or property rights65 creating uncertainty as to both what harms may be claimed and what constitutes an appropriate remedy.66 Moreover, accurate information problems are not as readily apparent or easily identifiable. Some legislators failing to see the problems posed by accurate genetic information actually deride proposed anti-genetic discrimination legislation as "a solution in search of a problem."67

[¶34] Given the problems generated by both accurate and inaccurate information, genetic information requires special protections. The best form of protection is to secure individuals' rights to control their personal genetic information without forcing exposure to unwanted, potentially harmful information, or allowing exposure to raw genetic or pathological information without appropriate counseling. Yet various other players also want to control, or at least access, the information, and allowing or prohibiting disclosure to those parties presents an array of legal issues.

Indecent Disclosure: Information Access and Control

[¶35] Both accurate and inaccurate nutrigenetic information pose serious potential hazards given the lack of effective regulation to prevent inaccuracies, and the even greater lack of legislation dealing with disclosure of accurate genetic information. The key to dealing with these problems revolves around access to information from nutrigenetic tests.68 Aside from the individual seeking the test, other parties also want this information. This section examines these stakeholders and their reasons for wanting the information, as well as the effects and legal issues involved in providing or proscribing that access. Regardless of the interested party examined, the dominant theme is the individual's loss of control.

Patient/Consumer: The Individual

[¶36] An individual may seek nutrigenetic testing for numerous reasons: to improve quality of life, to reduce health care costs, or just to follow the latest trend. Whatever the reason, "[i]t is axiomatic that a person who has been tested for one or more genetic conditions has a significant interest in knowing and determining what happens to the resulting information."69 As a Ninth Circuit judge recently put it, DNA does far more than merely identify a person: "DNA stores and reveals massive amounts of personal, private data about that individual, and the advance of science promises to make stored DNA only more revealing in time."70

[¶37] Yet unrestricted access to nutrigenetic information, even to the individuals themselves, raises previously mentioned problems of misunderstanding and harmful disclosure. Particularly in light of the lack of pre- and post-test counseling in the context of nutrigenetics,71 misinterpretation is a strong possibility.72 When unwanted information emerges from these reports, it may reinforce deterministic views.73 In addition, "[r]eleasing test results to lay consumers, who are not educated in such matters as genetic testing or qualified to understand the information contained therein poses inherent psychological dangers."74 Of course, not all genetic information is dangerous – much genetic information is itself harmless, and not the type that would be used for discrimination (such as eye color or lactose intolerance). The problem is that with the large number of genetic variants being tested and discovery of new correlations of a particular genetic variant, one cannot know whether the information received will remain innocuous or will be imputed meaning making it dangerous.

[¶38] In some cases, this may lead to serious identity issues, or even suicide.75 Even if consumers grapple with the implications of the information, they may be placed in the difficult position of either having to lie or having to face potential discrimination from employers and insurers asking for any genetic testing results received by the individual.76 There may also be concerns about the implications for family members, particularly those who share the same DNA. Family members may have an interest in the genetic information for their own personal health. Yet, for some, "the prospect of knowing genetic information elicits feelings of anxiety and can even cause family ties to become strained when family members do not want to know the information."77 Use of one family member's DNA has been employed to identify, through forensic databanks, a relative who committed a crime,78 and to deny insurance.79

[¶39] As a result of these fears, many individuals have forgone testing even though it could lengthen and improve their quality of life.80 Even those individuals wanting to improve their lifestyle with genetically-tailored recommendations have important reasons to want not to know anything beyond the specific information requested.

[¶40] Given these critical concerns, the safest option may be to prohibit individuals from obtaining nutrigenetic tests, or perhaps to allow only a licensed professional to decide whether the person adequately understands the implications before a test may be ordered. Yet such paternalism seems diametrically opposed to the individual liberty valued by American society, and implicates autonomy and self-determination issues.81 Preventing individuals from obtaining nutrigenetic information also has various legal implications. Restrictions on obtaining one's genetic information may arguably amount to unconstitutional infringement of substantive due process rights.82 In fact, the Ninth Circuit asserted that "[o]ne can think of few subject areas more personal and more likely to implicate privacy interests than that of one's health or genetic make-up."83 Such restrictions on obtaining personal genetic information may also implicate property rights. Four states have statutes saying that genetic information is personal property. As a result, impeding access to that information may potentially constitute a taking.84

[¶41] In sum, nutrigenetic testing involves balancing the desire to encourage individuals to obtain health benefits from their genetic information while protecting them from unwanted overexposure and unnecessary disclosure to third parties. Given that genetic information "relates to them and can affect their lives in profound ways," individuals have "a very strong claim to control the circumstances in which this information is generated and to determine what happens to the information subsequently."85

Commercial Testing Services

[¶42] Companies that provide commercial nutrigenetic testing services have an obvious interest in obtaining genetic information-the nutrigenetic information is the product they sell to consumers. Yet their interest does not end upon completing the testing and sending back the results. Companies providing genetic testing also have a strong interest in retaining the genetic information and any personal information of the individual who supplied the sample. By storing this information in databases, a company can continue developing new services by exploiting the larger sample sizes to find new correlations relevant to nutritional recommendations. Thus, companies simultaneously make money from the services provided and obtain samples to improve the services they offer.86

[¶43] Allowing commercial test providers access to raw genetic information gives rise to several concerns.87 Once the individual sends off her genetic sample, she has little control over who else will have access to it. Much like an email, the initial recipient may forward the information to others. Some internet genetic testing services, for example, apparently sell the genetic information they obtain to research institutions.88 These services may also store the DNA or the test information to create genetic databases themselves. The key here is loss of control and the resulting harm to individuals.

[¶44] Companies engage in these practices without the knowledge of the individual, thereby implicating informed consent issues. In the medical context, courts hold that doctors have a duty to disclose their financial interests, but this is based on the idea that a doctor has a fiduciary duty to a patient.89 A court may have more trouble finding such a duty in an arms-length commercial transaction. Moreover, the private sector, which is focused solely on its own financial gain,90 is more likely to "misuse this sensitive information in times of economic crises, such as selling it in the event of bankruptcy."91

[¶45] In many instances, consumers of genetic testing products are not informed that their information was passed on or sold to third parties, or used for purposes other than to provide the product ordered. Even in instances where the commercial service provides a disclaimer, whether the consumer actually understood the implications of that consent is unclear.92 Unintended use issues are particularly alarming given not only the large number of genetic variants being tested,93 but the permanence of genetic test results and the effect on others, such as family members who share the same DNA. The genetic testing website quoted earlier portrayed nutrigenetic information as "last[ing] a lifetime,"94 but actually the unique longevity of DNA "creates the possibility of long-term and even transgenerational harms for persons."95 Genetic information continually gains meaning, as more and more associations between genes and various conditions are discovered. Yet even though exponential growth in genetic knowledge may reveal information individuals do not want themselves-much less revealed to others-to know, it is not easy to withdraw that information.96

[¶46] Proscribing these commercial entities from obtaining genetic material and offering their services raises a different set of problems. Restricting the marketing of these tests, for example, implicates First Amendment rights.97 Because the Supreme Court extended First Amendment protections to commercial speech, marketing restrictions may infringe that First Amendment protection.98 Another difficulty is that limiting market players potentially hampers general access to the tests.99 The problem becomes even greater when considering researchers, who are not purely profit driven, but also seeking to make scientific advances.

Researchers/Biobanks

[¶47] Researchers and biobanks constitute another category of interested players. Studies of large cohorts linking genetic information to details about dietary habits and lifestyle factors are "key to unlocking the details of how genetics and environmental exposures, including nutrition, interact."100 Though public good may motivate much of these efforts, the information is again used for purposes never intended by the individual ordering a nutrigenetic test.101 Moreover, individuals may find it incredibly challenging to withhold or withdraw consent for future use. Once researchers have the information, preventing them from using it can be very difficult. Again, the main problem is loss of control.

[¶48] Societal benefits of allowing researchers and biobanks access to genetic information may be lost if this access were proscribed. Researchers argue that genetic information, coupled with the personal information provided, is needed for meaningful results. Yet the ability of researchers to access personal information about specific individuals suggests much greater threats to individual autonomy.102 The resulting implication is that this creates a conflict of interests between the need for research and the right to individual autonomy.103 This view, however, overlooks important aligned interests-the researcher actually benefits by protecting individual genetic autonomy. Concern about lack of control not only harms patients who forego potentially beneficial testing, but also hurts research.104 Currently, many researchers face significant problems in recruiting study participants, as people are unwilling to participate in studies for fear that such participation may lead to third party disclosure, resulting in discrimination and other negative effects. Protecting individuals' autonomy over access to their genetic information therefore can be mutually beneficial: alleviating patients' concerns by eliminating the main reason they currently refuse to participate in genetic research conducted by academic or commercial researchers.

Physicians/Health Care Providers

[¶49] Health professionals use genetic information to gain a fuller understanding of their patients.105 Issues concerning the individual's loss of control, similar to those arising in the context of research institutions, surface when the physician uses the information for research without patient approval.106 A separate issue, however, appears when a doctor is compelled to disclose the information to third parties. Medical information on file with a doctor must often be disclosed to insurers, for example. When the employer is also the insurance provider, there are further concerns that information will be disclosed to the employer.

[¶50] There is precedent to suggest that physicians in some circumstances may be obligated to reveal the information to family members.107 In not doing so, physicians may face liability for failing to meet their duty to warn. In Safer v. Estate of Pack,108 for example, the New Jersey appellate court recognized "a physician's duty to warn those known to be at risk of avoidable harm from a genetically transmissible condition." The court explained that "[i]n terms of foreseeability especially, there is no essential difference between the type of genetic threat at issue here and the menace of infection, contagion or a threat of physical harm."109 In a case of first impression, the Supreme Court of Minnesota recently followed the lead of the Safer court by accepting the plaintiff's argument that a physician's duty to warn others of a patient's genetic disorder arises from the foreseeability of injury, even if a physician-patient relationship cannot be established.110

[¶51] While the courts grapple with these issues, problems of not allowing physicians access to genetic information become evident. First, if physicians do not have access to genetic information, important protections may be lost for the patient. Health professionals provide an important safeguard function in interpreting and protecting the data, and explaining the actual ramifications. Second, physicians may be liable to the patient if they do not consult genetic information, for example, before prescribing medications.111 In fact, some recent articles have suggested the increasing likelihood of doctor liability for failing to test for genetic variations may be an impetus for increasing the progress of pharmacogenetics, for example.112

[¶52] While many of these problems remained dormant in the context of pathologic genetic testing, nutrigenetic testing has changed everything-pushing privacy issues from the relative safety of the doctor's office to the market place, and moving to an exponentially larger magnitude of testing that brings with it exponentially greater room for misinterpretation, discrimination through release to third parties, and self-overdisclosure. Regulations, on the other hand, thus far remain unchanged.

Not Getting What We Need: Limits of Current Regulations & Previous Proposals

[¶53] Inaccurate and accurate information disclosure problems, coupled with the numerous parties who seek to exploit genetic information, pose significant hazards. Yet as genetic testing expanded exponentially over the last decade, regulatory and legislative efforts never gained momentum and today remain woefully inadequate. Current regulatory efforts, where they do exist, do not protect against many of the problems posed by genetic information generally. Nor are the current proposals, both by academics and before Congress, sufficient to prevent the opening of the Pandora's Box presented by nutrigenetic testing.

The Current Regulatory Regime

[¶54] Calls for increased oversight of genetic tests have been made for nearly a decade, yet federal and state regulation remains patchy at best. The Secretary's Advisory Committee on Genetic Testing (SACGT) set forth its findings nearly seven years ago that "[b]ased on the rapidly evolving nature of genetic tests, their anticipated widespread use, and extensive concerns expressed by the public about their potential for misuse or misinterpretation, additional oversight is warranted for all genetic tests."113 Yet FDA regulation, the Clinical Laboratory Improvement Amendments, Health Insurance Portability and Accountability Act of 1996 (HIPAA),114 and state legislation have all been unsuccessful in providing adequate safeguards.

Federal Agencies

[¶55] Oversight of all laboratory tests and their components falls within the purview of the Food & Drug Administration (FDA), pursuant to the Federal Food, Drug and Cosmetic Act.115 Some authors suggest that the FDA is in the best position to protect the public from genetic test problems, and that the profound dangers of genetic information "warrant the public delegating the resources and mandate to the FDA to ensure that the troubling issues and agonizing choices occasioned by genetic testing are not compounded by poorly developed or even misleading information."116

[¶56] Despite its arguably broad powers to act in the area,117 current FDA regulation of genetic testing is minimal. Though there are "genetic tests available for close to 1000 diseases or conditions . . . only about a dozen genetic tests have been reviewed and approved . . . to ensure their safety and effectiveness."118 Furthermore, FDA regulation is incoherent and vacillating. For example, the FDA deems genetic testing kits-classified as medical devices-subject to pre-market approval, yet genetic testing services (including nutrigenetic testing) are not.119 In fact, "[c]linical laboratories that plan to market tests as services and that have not received federal funds are under no requirement to consult [independent review boards (IRB)] . . . . [and] few have sought IRB approval or consulted the FDA."120 Because nutrigenetics is not testing for the presence of a single marker, but rather involves complex evaluation of numerous different genetic variants, nutrigenetic test kits are unlikely to be offered any time soon. At present, nutrigenetics remains a genetic testing service and thus part of the market which the FDA has barely acknowledged, much less regulated. Overall, FDA policy and statements indicate an unwillingness to regulate genetic testing services, whether because of lack of political will or lack of resources.121 Even if the unwillingness or inability of the FDA to regulate genetic testing services were overcome, real concerns remain regarding the FDA's "competence to address the complex social issues attached to genetic testing which go beyond mere product performance concerns."122

[¶57] Another proposed candidate for regulating genetic testing services is the Federal Trade Commission (FTC)123 because its mandate under the Federal Trade Commission Act is to prevent "unfair or deceptive acts or practices in or affecting commerce."124 Effectively addressing the combination of accurate and inaccurate information problems presented is virtually impossible given the limitations on the FTC (and other federal regulatory agencies). The mandate of these agencies is generally confined to addressing inaccurate information problems. Accurate nutrigenetic information does not fall within the purview of unfair or deceptive business transactions.

[¶58] Yet, neither the resources of these agencies, nor legislative support for ensuring that genetic information is at least accurate, reach that far. Fully addressing these myriad problems through federal regulatory agencies would require vigilance, resources, and concerted interagency efforts, as well as legislation recognizing and addressing the problems inherent in nutrigenetic information. Unfortunately, legislation currently underpinning much of the existing regulatory framework is sparse and often not focused on the overarching problems.

Federal Laws

[¶59] Although several federal laws touch on genetic information issues, "this patchwork of laws and interpretations, untested in the courts, does not adequately address the unique issues surrounding the specific use of genetic information."125 First, the Clinical Laboratory Improvement Amendments (CLIA) of 1988126 establish minimum quality levels in laboratory testing practices. Although CLIA may theoretically extend to federal oversight of DNA analyses,127 in practice there is much room for improvement.128 Although various governmental advisory bodies found that "a smooth transition of genetic testing from research to practice" would require "creat[ion of] regulations under CLIA that focused specifically on genetic tests," CLIA has no specific category or requirements for genetic tests.129 Because genetic tests are broadly included as part of all laboratory tests, there are no specific personnel, quality control, or proficiency-testing requirements for the vast majority of genetic tests.130 As a result, nutrigenetic tests are "sometimes performed in laboratories that have not been approved under CLIA."131 The effect of delays in implementing CLIA, not to mention its gaps, means that "neither healthcare providers nor consumers can be confident in the oversight mechanisms in place to ensure genetic tests are accurate and reliable. While genetic science and genetic technologies have leapt into the 21st century, the agency entrusted with ensuring laboratory quality is stuck in the past."132

[¶60] Most importantly in this context, CLIA does not address the serious issues relating to genetic counseling or informed consent. Finally, CLIA arguably does not fit the paradigm of genetic testing because of the huge number of tests involved in nutrigenetics. The 50K to up to 1M tests (analyzing 50,000 to up to 1,000,000 genetic variants for one person) used for pharmacogenetic, ancestry, and other developmental testing are already orders of magnitude higher than what can reasonably be quality-controlled under CLIA.133

[¶61] Second, HIPAA is frequently cited as a protection in the context of genetic testing. HIPAA provides comprehensive protection to individually-identifiable health information. The statute is not focused on genetic information specifically, but it does provide that genetic information may not be treated as a condition "in the absence of a diagnosis related to such condition."134 Yet this indirect and minimal approach to protecting genetic information is inapposite to deal with the large number of concerns presented by genetic information. The statute is full of gaps that cut down the limited protections afforded. For example,

HIPAA does not require that insurance plans offer coverage for genetic disorders or restrict the amount, level, extent, or nature of the benefits or coverage for similarly situated individuals enrolled in the plan or coverage, but instead prevents an insurance plan from applying the premiums or exclusions on a genetically discriminatory basis. Thus, insurers, subject to any binding state regulations, may continue to consult genetic information in determining eligibility and setting premiums for individual plans. Roughly 23.5 million Americans are enrolled in individual plans, therefore a significant regulatory gap exists.135

[¶62] HIPAA is designed to protect confidentiality of health records generally, and is not focused on the special issues surrounding genetic information. In fact, genetic information is only protected if it falls under the definition of protected health information.136 Treating genetic information as no different from other health information overlooks that the differences-permanency, effects on relatives, and future information-are precisely why heightened protections for genetic information are needed.

State Legislation

[¶63] State efforts to provide genetic testing oversight currently share many of the problems of federal regulations. State legislation, however, has made more headway than federal legislative efforts. Seventeen states have prohibited direct consumer access to any laboratory testing. Thirty-one states have genetic privacy laws, forty-seven states have genetic non-discrimination in health insurance laws, and thirty-four states have genetic non-discrimination in employment laws.137 Yet these statutes are incomplete even when pieced together, leaving numerous problems unaddressed. First, the state laws are by no means uniform, but contain different definitions of the relevant terms, such as genetic information, genetic tests and discrimination.138 Second, the state statutes contain significant gaps which leave genetic information unprotected from exploitation or nefarious purposes. Although some states have implemented measures that indirectly regulate some aspects of genetic testing services-such as quality assurance requirements beyond those mandated by CLIA and genetic counselor licensing requirements-nutrigenetic testing falls largely outside the realm of those regulatory efforts.139 Third, despite their good intentions and efforts, none of the state laws afford individuals the autonomy to control fully who gets access to their genetic information. Finally, as jurisdictional issues involving services offered through the internet remain judicially unresolved, even the most stringent state laws may not offer the necessary measures to protect information affecting individuals and their families because whether a web-based genetic testing service is subject to a particular state's jurisdiction remains uncertain.

[¶64] Even if existing federal and state regulations worked exactly as intended, third party disclosure and self-overdisclosure of genetic information-and nutrigenetic information in particular-give rise to problems that remain overlooked and inadequately addressed by the federal and state governments.

Other Proposals

[¶65] Recognizing the shortcomings of current regulation and legislation, various types of proposals attempt to improve the status quo. These proposals generally revolve around three ideas: (1) an informational, informed consent-based approach; (2) anonymization; or (3) stricter governmental regulations. An assessment of these approaches reveals their shortcomings, particularly in the dynamic setting of nutrigenetic testing with the exponential growth of tests for genetic variants. Many of the proposals are so concerned about impeding researchers' access to information, however, that they fail to recognize the benefits to research. The current unwillingness of people to participate in research studies for fear of third party disclosure can actually be most effectively addressed by protecting the individual's autonomy rights.

Informed Consent Models

[¶66] Some critics suggest that the "essential challenge of this policy reform is going to be the development of ethically justified consent processes and forms that responsibly balance the ethical obligations to respect subject autonomy and protect privacy with the scientific and clinical benefits of data release."140 Indeed, many genetic information related proposals focus on informed consent,141 which requires the individual to be in possession of relevant facts. Legally, informed consent does not mean that the individual must actually comprehend the information.142

[¶67] To remedy this lack of comprehension, the focus of many informed consent based proposals is to enhance the quality of information to enhance the individual's comprehension, yielding not only consent, but also informed choice on the part of the individual. Thus, these proposals often address the type of information that should be provided and more effective delivery of that information. One information-based proposal, for example, is modeled on the Truth in Lending Act,143 arguing that "[t]he underlying problems of the 1960s consumer credit market are virtually identical to modern concerns about non-pathologic elective genetic testing" and that "[i]n both situations the lack of accurate and understandable information leaves consumers ill-equipped to make very important personal decisions."

[¶68] Many researchers also prefer the informed consent paradigm to other approaches. In fact, informed consent schemes generally allow researchers a great deal of control. As long as the individual originally consented to supplying the sample and the possibility of the sample being used for research, researchers control the genetic information.144 The focus of these proposals, therefore, is ensuring that initial informed consent was legally adequate. For example, one proposal to safeguard information calls for "a description of the test and a statement of its purpose; a description of the disease(s) or condition(s) for which a test will be conducted; an explanation of the risks of stigma and discrimination; and assurances that the patient's medical confidentiality will be protected," except as explicitly stated.145

[¶69] Because this approach requires genetic testing services to provide a certain amount of educational material explaining the limitations of the tests, it could alleviate some problems of accurate information relating to misunderstandings, such as misinterpreting the information as determinative or conclusive. Moreover, individuals would at least be aware that information may later be used to discriminate against them before deciding to undergo testing.

[¶70] The limitations, however, are significant. First, the informed consent paradigm does not prevent discrimination. Instead, it merely warns the individual that discrimination may result. Thus, rather than being protected, the individual is simply discouraged from getting the test. Second, even in the purely medical context-dealing solely with pathologic issues-informed consent is abstruse. Different courts vary widely in their application of informed consent, from the extent of disclosure necessary to the standards by which courts determine whether disclosure was adequate.146 Courts have, however, largely agreed that there is no fiduciary duty requiring the health professional to disclose risks that may have nonmedical implications, such as economic or social drawbacks.147 In addition, the health professional's obligation is a duty to disclose, not to ensure that patients fully comprehend what has been disclosed to them.148

[¶71] Third, the informed consent model seems ill-suited to the commercial, direct-to-consumer context. Even assuming that regulations could mandate that genetic testing services require that testing providers supply relevant information to patients and subsequently require informed consent agreements to be signed stating that the consumer wants to proceed with the test despite the risks, the result may simply be point-and-click or click-through agreements. Most people do not actually read through these agreements before ordering services through the internet.149 Whether such click-through forms would be any more effective than currently available click-through contracts in facilitating informed consent is unclear. Thus, despite addressing some of the accurate information concerns, there are still significant problems concerning both accurate and inaccurate genetic information, which the informed consent model fails to address.

Anonymization Models

[¶72] Anonymization proposals seek to draw on the success of the HIV anonymization model, though case law dealing with anonymization of general medical information highlights significant drawbacks to this approach. Anonymization is premised on the idea that without identifying personal information, data does not threaten individual privacy. Data may be anonymous from the outset, or it may later be anonymized at the collection, retention, or disclosure stages.150 Anonymous AIDS testing creates anonymity from the outset. Unlike confidential testing, where the individual's name is recorded and linked to her test results, anonymous AIDS testing uses code numbers to identify the test-names are never linked to the results.151

[¶73] Parallels drawn between HIV/AIDS tests and genetic testing suggest that anonymous testing could be successfully extended to genetic testing. Both give rise, for example, to concerns about discrimination and lack of pre- and post-test counseling. Despite these similar concerns, there are significant problems with relying on anonymous testing in the context of nutrigenetics. First, personal information is needed to make nutrigenetic recommendations, whereas this is not required for determining whether an individual is HIV-positive. Second, unlike HIV/AIDS testing, genetic testing involves new genetic relationships constantly being discovered and raises possibilities of later revealing other much more serious conditions. Moreover, when tests are done anonymously they do not become part of an individual's medical record; as a result, physicians may fail to catch serious health concerns.152

[¶74] Another approach more frequently proposed in relation to genetic testing focuses on post-test anonymization. Removing or obfuscating any identifying information is thought to sufficiently protect the individual's privacy even if the anonymized data is disclosed.153 Based on this idea, for example, federal regulations and international guidelines routinely permit use of anonymous tissue samples in research even without consent of the original donors.154

[¶75] The greatest problem of anonymizing genetic information is that "DNA carries so much information that anonymization may be difficult or impossible."155 Some argue that an individual's "right to privacy is violated when personal medical information is revealed to an unauthorized third party . . . even if such information is rendered anonymous by the removal of all data relating to the [individual's] identity."156 The right to privacy understood in this manner means not only protecting one's identity, but involves "[the] person's ability to control access to information about oneself,"157 whether or not it is known to be about the individual.

[¶76] Current law, however, fails to provide for individuals' rights to retain autonomous decisionmaking authority over the use of genetic data. Though case law and statutes recognize a right to privacy, the right is significantly limited, extending only to identifiable medical information.158 In fact, federal regulations actually "exempt anonymized samples from the requirements of informed consent . . . [allowing] researchers [to] remove identifiers from existing samples [or data] without seeking consent for their use in data analysis."159 Still, some researchers argue for greater physician and researcher control over data in biobanks,160 maintaining that anonymization has limited value in protecting participants' interests because "[i]t may not decisively cut the link to a specific individual, it prevents the use of samples for purposes such as diagnostics, it may not prevent harms to groups, and it does not rule out wrongdoing."161 They therefore argue that the right to withdraw consent should be restricted to cases where the donor can present sufficient reasons, with the researchers or biobankers determining whether the reason is "sufficient"-that is, whether researchers believe that the reason is based on "genuine, deeply felt concerns . . . not based on misconceptions."162

[¶77] Many researchers generally disfavor anonymization models because of the limits it places on their ability to make meaningful use of the data. Arguing that research interests are not the inherent problem that genetic information concerns need to address, researchers are often among those that argue instead for stricter governmental regulations to prevent nefarious uses of genetic data without impeding access of researchers who will use the genetic information for medical progress and societal benefits.

Models Focusing on Stricter Regulations

[¶78] Current regulations do not address many areas of concern regarding genetic testing services.163 Despite different ideas as to what the appropriate approach should be, there is widespread support outside of the regulatory agencies themselves for stricter regulations.164 Yet, the shortcomings previously discussed highlight only some of the problems impeding progress in that area. As one commentator put it, "[d]espite this near unanimity [of the SACGT and commentators], the clamor for increased regulation . . . is receiving little attention [from regulators]."165 Legislative mandates may be more effective in guiding regulatory efforts and clarifying the reach of protections.

New Legislative Efforts

[¶79] Because of the uniformity required to protect individuals' privacy and autonomy regarding their genetic information, federal legislation is most suited to supply the needed legislative mandate. CLIA, HIPAA and other federal legislation are not adequately focused on genetic information issues to address the problems of accurate and inaccurate information, particularly in the context of nutrigenetics.166 As one critic and member of Congress contends, "[t]hese laws leave many gaps in protections, which fail to alleviate the public fear of genetic testing, and the ambiguity of current law has resulted in both actual and perceived acts of discrimination leading to an inconsistent application of laws to deal with such grievances."167 Despite sluggish progress,168 some recent congressional efforts attempt to address certain genetic information issues.

[¶80] The Genetic Information Nondiscrimination Act (GINA) demonstrates continuing efforts by legislators in both the House and Senate to introduce federal genetic information protections.169 GINA seeks to protect against genetic discrimination both by employers and insurance companies. However, strong opposition by powerful groups, including the U.S. Chamber of Commerce, has blocked the bill from becoming law to date.170 Despite these impediments, the pending legislation is an important step that should be taken. This legislation alone, however, is insufficient to address the multitude of problems posed by nutrigenetic testing.

[¶81] First, the proposed legislation originally defined genetic information as "genetic tests of an individual or family member . . . used to predict risk of disease in asymptomatic or undiagnosed individuals."171 This definition did not reach nutrigenetic testing (or other lifestyle-related genetic testing), which looks for patterns of genes that interact with diet in certain ways but do not look for "disorders" or "diseases." The 2007 version actually eliminated the clause "used to predict risk of disease in asymptomatic or undiagnosed individuals," thereby eliminating the language excluding nutrigenetic testing.

[¶82] Second, the act attempts to ban discrimination by prohibiting insurers and employers from using the information for discriminatory purposes. It does not, however, address the risks of misinterpretation inherent in disclosure to the individual. Nor does it address the stigmatizing effects. Finally, it creates a system that relies on litigation for enforcement. Other than the large costs this can involve, GINA also fails to consider that in many instances employees may not know that they were denied coverage or unemployment due to their genetic profile. Even if the individual suspects genetic discrimination, who carries the burden of proof (does the plaintiff have to show proof of discrimination, or does the defendant have to show that there was no discrimination?) or how a court would assess whether there was discrimination remains unclear. Thus, although the bill is an important step in clearly stating that genetic discrimination is prohibited, it leaves unaddressed problems of misinterpretation and self-overdisclosure, and carries practicality problems.

[¶83] Another bill, the Genomics and Personalized Medicine Act of 2006 (GPMA),172 proposes to facilitate the advancement of personalized medicine, and as such seeks to "expand the use of molecular tests and therapeutics, the backbone of personalized medicine."173 Like GINA, this is an important piece of legislation that should be passed, but it too is insufficient to protect genetic information. In fact, in its current form, it seems the bill does not even apply to nutrigenetic information. The bill is focused on pharmacogenomic testing (examining the interactions of pharmaceutical drugs with specific genetic variants). In failing to address nutrigenetic testing, the GMPA overlooks that nutrigenetic testing (examining the interactions of nutrition with specific genetic variants) poses many of the same problems, as well as the additional problems created by the commercial, direct-to-consumer context.

[¶84] Second, though the bill purports to "protect[] consumers by reaffirming Congress' commitment to stopping genetic discrimination and protecting genetic privacy, "174 the bill is largely focused on the problems of inaccurate information, rather than on creating protections to also alleviate concerns about accurate information. For example, the bill dictates "direct-to-consumer genetic tests to receive greater scrutiny and regulation."175 The concern is thus primarily that of ensuring the accuracy and availability of tests. Consequently, the bill does not address many of the discrimination and self-overdisclosure problems presented by accurate genetic information. Moreover, the bill sets forth relatively few concrete protections, focusing instead on forming advisory panels to further explore the problems.

[¶85] Finally, the GPMA does not protect the autonomy of the individual to control which third parties may access and use that individual's genetic data. The legislation therefore does not address the primary concerns preventing individuals from participating in research studies.

[¶86] Although the proposed federal legislation-both GINA and GPMA-would provide useful protections and should be passed, they leave open gaps posing significant dangers to individuals in the form of discrimination, misinterpretation, and inaccuracies. Moreover, the proposed statutes do not actually reach nutrigenetic testing. Thus, further measures are required to protect individuals' genetic information from self-overdisclosure or harmful third party disclosure.

A Solution to Protect Genetic Autonomy and Control

[¶87] Interest in nutrigenetic testing is rising, but the differences between nutrigenetic and traditional pathologic genetic testing remain unaddressed by previous approaches. The amount of genetic information such tests generate is much larger than traditional genetic tests, but the accuracy and reliability of that information is more questionable than that provided by traditional tests. Problems persist even if the information is accurate, particularly in light of the many parties interested in the information for very different purposes. Given the problems inherent both in allowing and in proscribing these parties' access, courts and legislators seem stuck between the proverbial Scylla and Charybdis.176 Current proposals to address the problem all miss the mark or leave wide gaps in protection. Despite the serious and numerous problems faced, however, there is a workable and practical solution.

[¶88] Individual autonomy over genetic information is the lynchpin to protecting genetic privacy while also maximizing the promise of genetic testing. Given its permanency, reach, and developing meaning, the key to protecting genetic information and preventing the many potentially associated legal problems is to allow individuals to control the information and permit disclosure to authorized third parties. At the same time, individuals themselves must also have protection from the adverse effects of unwanted information. This can be accomplished through a double-masking system that separates the raw genetic information from derived information before giving the information to consumers.177 Rather than hope that businesses voluntarily adopt such protections, Congress must pass legislation providing a uniform federal requirement to avoid the permanent and devastating effects likely if genetic information, particularly seemingly innocuous nutrigenetic information, is not protected.

Double-Masking: A Model to Protect Genetic Autonomy and Privacy

[¶89] The testing process would start when the individual visits a nutrigenetic website and chooses to obtain testing. The website provides a downloadable program that comes with a unique anonymized number (e.g., 123-456), which is linked to an anonymous electronic mailbox. The individual sends a cheek swab to the testing service with the anonymized number attached. The individual separately pays for the tests and gets a payment authorization code (e.g., UVW-XYZ) that verifies payment for a particular service, but does not retain any of the individual's information. The individual then informs the anonymous electronic mailbox that payment has been made by entering the code. The laboratory receives the swab, checks the mailbox to see if payment was made,178 conducts the test, and sends the encrypted genetic information to the anonymous electronic mailbox identified by the ID number. The individual then downloads a program from the nutrigenetic testing website encoded with the appropriate algorithms based on rules provided by the laboratory. The program requests personal information necessary to answer the query (such as age, sex, pregnancy status, and so forth). Once the individual enters the information, the algorithm creates recommendations based on the specific genetic data.179 The program runs client-side, which means it runs on the individual's computer rather than on a server or central computer of the nutrigenetic testing website. Thus, personal information can be entered without anyone else, including the nutrigenetic testing provider, knowing or recording it.180

[¶90] The individual then receives the derived nutrigenetic information without ever learning which specific gene variants were examined to derive that information. So, the individual not only does not know the raw genetic information underlying the nutrigenetic recommendations, but does not even know what tests were run. The process itself is run through a laboratory, with a certified clinical geneticist who determines which information may be released this way to a patient. The geneticist would ensure that only nonpathologic information is released through the program, leaving release of pathologic information to licensed health care professionals, such as genetic counselors and physicians. So far, all of the privacy problems discussed previously have been avoided because no one has access to both the raw genetic information and the individual's identifying information.

[¶91] The individual, however, is not prohibited from obtaining further information, including the raw genetic information. To do so, the individual can release the data to a licensed physician or genetic counselor who can provide adequate counseling before giving the information sought, including the raw genetic information. The individual provides the licensed health care provider the code to the license number and the patients' computer URL. The system then verifies that this is a licensed healthcare professional against a database of licensed healthcare providers. If the professional is not in the database, the licensing must be certified and the name added to the database by the system curator before information is released.

[¶92] Individuals can also authorize the release of the raw genetic information to their physicians for other purposes, and they can be contacted by researchers, biobanks, or other parties interested in using the information. The individuals will never be directly contacted, but can receive research participation requests by periodically checking their anonymous mailbox. This way, individuals can contribute to research efforts but ensure that their information is not transmitted to unauthorized or unwanted sources, such as insurance companies.

[¶93] The double-masking model provides a relatively straight-forward and practical way to preserve individual autonomy while also allowing the potential personal, medical, and societal benefits of genetic testing to be realized. Thus, double masking demonstrates that it is not only desirable, but feasible to protect individual autonomy over genetic information.

Comparing the Double-Masking System to Previous Proposals

[¶94] As theoretical issues and technological realities are recognized and incorporated into proposals to protect genetic information from potentially devastating generations of people, the double-masking model offers a relatively simple and workable system that addresses the most critical information concerns-specifically, the accurate information concerns widely unaddressed or inadequately addressed by legislation. One of the greatest strengths of this model is that it incorporates the strongest aspects of the informed consent and anonymization models.

[¶95] Significantly, double masking does not displace regulatory efforts, but compliments and completes a strong regulatory regime, including the proposed Genetic Information Nondiscrimination Act and Genomic & Personalized Medicine Act. While the particulars of the legislative efforts are worked out and the impact of nutrigenetics and lifestyle genetic testing on genetic information privacy and autonomy becomes clearer, the double masking model provides real protections and obviates many of the legal problems previously highlighted by preventing the irreversible and uncontrolled release of genetic information.

[¶96] Allowing people to receive genetically tailored recommendations without releasing unwanted information to either the individual or to third parties without further review avoids future legal problems such as insurance or employer discrimination. Autonomy is preserved by providing the option of obtaining the raw genetic information through a licensed physician or genetic counselor, who will provide the necessary background information to avoid, as far as possible, misinterpretation of the data. Yet relying on businesses to voluntarily implement a program that provides these protections is not sufficient. The extreme sensitivity and permanence of this information necessitates a uniform and mandatory requirement, enacted through Congressional legislation.

Legislating Double-Masking Protections

[¶97] Safeguarding nutrigenetic information requires congressional action, ensuring that no gaps leave individuals vulnerable or afraid to undergo nutrigenetic testing. The double-masking model is currently the best way to protect against self-overdisclosure, harmful disclosure to third parties, and misinterpretation. To broadly account for possible future developments, however, legislation should also be passed to more generally ensure for genetic information autonomy, with provisions mandating the essential functions provided by the double-masking model. Therefore, Congress should pass legislation that (1) protects individuals from self-overdisclosure and (2) gives individuals control over third-party disclosure. The double-masking model could be implemented to satisfy regulations pursuant to the enforcement of that legislation.

[¶98] A genetic information autonomy act could be framed as a bill to protect individuals' rights to control their genetic information from unwanted or harmful disclosure, thereby encouraging individuals to benefit from genetic testing and participate in structured research of great commercial and public health interest. This recognizes the overlapping interests of both researchers and individuals in supporting this legislation, rather than erroneously portraying individuals' interests as divergent from that of researchers.

[¶99] The provisions of such a bill should address the three problems that are most overlooked under existing and proposed legislation and regulatory efforts: harmful and unwanted disclosure, misinterpretation, and self-overdisclosure. Three key provisions would address all of these issues:

Section 1. Derived Genetic Information.
Direct-to-consumer genetic testing services shall disclose only derived genetic information directly to individuals except as provided in Section 3, and shall ensure that reverse decoding of the underlying raw genetic data is not readily possible.
Section 2. Raw Genetic Information.
Raw genetic information shall be disclosed to individuals only by a qualified healthcare professional, and only after the individual has given explicit, informed, and uncoerced consent.
Section 3. Third Party Access.
Third parties may obtain access to the information only after receiving explicit, uncoerced, and fully informed authorization from the individual, and may not combine an individual's genetic information from different data sources without the originating individual's explicit, uncoerced, and fully informed consent.

[¶100] The first provision protects individuals from the harms of receiving information that may later be given meaning completely unrelated to nutrigenetics, and which might have devastating effects on the individual.181 In addition to preventing self-overdisclosure, this provision also encourages consumers and nutrigenetic testing providers to make the most of the promise of genetic testing benefits by allowing the derived genetic information to be readily obtained and transmitted.

[¶101] The second provision provides a safeguard for mitigating the problem of accurate genetic information leading to misinterpretation, by allowing individuals to obtain raw genetic information, but only through licensed genetic counselors or physicians to whom they have released the information. Because these licensed professionals can explain the risks and reasons why one may want to refrain from learning the raw genetic information, this provision provides another protection against self-overdisclosure. This requirement is a procedural safeguard to protect individual autonomy and the right to obtain personal information while also protecting the privacy right not to know unwanted information.

[¶102] Critics may urge that individuals should be able to access their own information directly without going through a licensed healthcare professional. Most people, however, have use only for the derived information, which translates the raw scientific data into actionable information, and would not feel like they were losing much, if anything, by receiving only that form of information in the first place. Furthermore, such restrictions are not novel; just as regulations require a prescription for potentially dangerous medicine, this provision prevents potentially toxic information from reaching customers without proper safeguards.

[¶103] The third provision addresses the problem of harmful disclosure to third parties. In requiring informed, uncoerced consent by the originating individual, this provision prevents information from being sold or otherwise transmitted to third parties who may use the information for discriminatory or otherwise harmful purposes. Granting the individual control also provides a tremendous tool for research. Guaranteeing that third parties will not be given access without explicit consent from the individual addresses the serious impediment of insufficient study samples that many genetic researchers now face. That is, individual control assuages fears of third party disclosure that currently prevent many people from participating in research.182

[¶104] Although the double masking model and the three provisions recommended to mandate the essential functions of that model are particularly helpful in addressing the heightened concerns in the realm of nutrigenetics, they would be just as appropriate to protect other types of genetic information. Whereas the first two provisions, on derived and raw genetic information, are arguably more important for the commercial context of nutrigenetics than the healthcare context of pathologic genetic testing, the third provision-dealing with third party access-would be particularly helpful in safeguarding all genetic information. Requiring explicit, uncoerced, informed consent by the originating individual before disclosing genetic information to third parties would avoid discrimination concerns while also providing assurances that would encourage individuals to participate in important genetic research, thereby maximizing the public investment in the Human Genome Project.

Conclusion

[¶105] Previous proposals regarding general genetic information protection identified many of the problems that also arise in the context of nutrigenetics. Yet the contextual change from a doctor-patient interaction to a consumer-business exchange places new dimensions on, and heightened urgency to, information problems. In particular, the changed context heightens accurate information problems of misinterpretation and discrimination, which are only exacerbated by the exponentially larger number of genetic variants being tested to provide nutrigenetic recommendations. The current regulations are patchy and insufficient to provide adequate safeguards.

[¶106] Though previous proposals have sought to address this inadequate system, these proposals not only fail to consider nutrigenetic-or any other nonpathologic genetic-testing, they also fail to protect individual autonomy. In doing so, these proposals fail to recognize that the positive effects of ensuring individual autonomy over genetic information will likely outweigh the drawbacks to research, because it eliminates the greatest impediment to recruiting research subjects. Previous proposals also largely focus solely on discrimination, and fail to address issues of self-overdisclosure. The double-masking proposal, by contrast, balances the right of control by the individual with the need to protect the individual from adverse effects of unwanted or unrequested information, while also creating a regulatory environment that alleviates fears and thereby encourages participation in research.

[¶107] Whether or not the legislation covers all genetic testing, or just addresses the particularly critical area of nutrigenetic testing, federal legislation must close the large gaps that currently exist by requiring testing providers to implement procedures that incorporate the essential features of a double-masking model-protection against self-overdisclosure, harmful disclosure to third parties, and misinterpretation. A uniform federal law will obviate disparate treatment of genetic information and different protections regarding genetic information accessed without individuals' consent. Without such a uniform law, there remains significant room for abuses and nutrigenetic information remains a significant risk. Enacting the suggested provisions focusing on derived genetic information, raw genetic information, and third-party access will allow nutrigenetic testing to provide countless benefits to individuals and society.

Pathologic genetic testing stands in contrast to "lifestyle" or "nonpathologic" genetic testing, which looks for interactions between diet and genes, to maximize quality of life and avoid disease.
