Curating Your Personal Genome?

When a member of the PGP-10 and an investor in 23andMe writes about curating one's online, personal data, a lot of people listen. Unfortunately, Esther Dyson (writing in MIT's Technology Review) does not mention the decision to share medical information or how she plans to curate her own genomic data online. Dyson rightly notes that "current website 'privacy' policies don't suffice. They're full of abstractions, euphemisms, and generalities, such as, 'We may, at any point in time, provide certain Specified Information to selected Marketing Partners ... .'" She appears to favor a complex, itemized consent policy, one that would allow users to opt in or out of sharing specific categories of information (user name, address, credit history, etc.) with a list of potential users (advertisers and other companies).

Imagine a similar consent for medical records sharing. For example, could someone like Esther consent to share her genome with a 23andMe social network, but not with researchers in this network? Or, perhaps, Esther could chose to share some of her genomic information, but not all of it. Then, again, maybe Esther would be willing to share her prescription history with an academic researcher, but not with pharmaceutical companies. The options could go on and on, resulting in an increasing complex array of choices.

Esther Dyson is obviously a very sophisticated information agent, but (as the opportunity to share medical information online increases) will the average user and patient be prepared to make informed decisions about the risks and benefits of participating? - J.O.

DNA Biobanks: The Five Minutes Between Nashville and Dundee

Here at PredictER we're very interested in the attitudes of healthcare professionals regarding DNA biobanking. In fact, we recently collaborated in a study of attitudes at a local children's hospital. Thus, I was excited to read the results of similar survey research from Vanderbilt University School of Medicine. David A. Leiman, Nancy M. Lorenzi and some other bioinformatics folk in Nashville appear to have been working on this topic for a few years now - beginning with focus groups in 2000 and including a recent international, comparative survey. In "US and Scottish Health Professionals' Attitudes toward DNA Biobanking" [J Am Med Inform Assoc. 2008 May-Jun;15(3):357-62. Epub 2008 Feb 28. | PMID: 18308988], the authors compare the attitudes of healthcare professionals in Nashville with the attitudes of those in Dundee, Scotland. While they expected that the difference between a mostly private (U.S.) and a more socialized (U.K.) healthcare system would impact attitudes, they discovered that the attitudes were not that far apart. Presumably, the authors thought that U.S. health professionals would worry that genetic information might be misused by insurance companies in the private healthcare system and, thus, would be less likely to support biobanking. As it turns out the attitudes of the two survey groups were very similar. Of the fifteen questions in common, significant differences in attitude were found on only three questions. The Dundee professionals were slightly less supportive of creating a DNA biobank and (most importantly) were less comfortable with the idea that they might be asked to consent patients for DNA samples.

In the discussion of the results the authors speculate that time constraints in Scotland might be at the root of this slight difference in professionals' attitudes about "consenting" patients into participating in the biobank:

While many U.S. practices are expected to see patients 12-15 minutes, Scottish doctors are expected to perform the same visit in 7-10 minutes. The additional burden of consenting, or even explaining a biobank project, may be an overwhelming challenge to integrate into the existing workflow.

Those "extra" five minutes of time in which to meet a patient's needs in the U.S., therefore, might account for the greater support ("Strongly Agree" versus "Agree") for DNA biobanking. The authors also mention the difficult nature of obtaining consent for this research – without a complicated: "Traditional consent procedures require researchers to contact participants each time a new investigation is undertaken with the same existing information". Let's hope that the validity of the patient's consent isn't sacrificed to better accommodate the busy schedules of the healthcare professionals. - J.O.

GINA, The Good News: Engaging the Public

This is the third post in a series of posts in which I share what I see as the ups and downs of the Genetic Information Nondiscrimination Act of 2008 (GINA or H.R. 493). In this post I address a potential positive:

A little discussed portion of GINA may be cause for celebration. Title II, Section 208, Subsection (b) of GINA calls for the establishment of the Genetic Nondiscrimination Study Commission after GINA has been enacted for six years. The purpose of the Commission is to evaluate the status of genetic science, genetic discrimination, public perception, and other factors, and to make recommendations to Congress regarding possible future legislation. Here, it would seem as though Congress has exercised a reasonable amount of foresight. Scientific knowledge is expanding at an amazing rate; faster than society and its laws can react, resulting in public fear and apprehension. Public fears are important and they must be listened to; public fears shouldn't always determine legislative action, but they cannot be brushed aside or ignored. In this case, Congress seemed to understand this dichotomy. They did the research. They listened to experts, and they acted. – Sam Beasley

ELSI After Francis Collins: What Now?

In an editorial published today, "This time it's personal" (Nature 453, 697 (2008) | doi:10.1038/453697a ), Nature adds to the many comments on Francis Collins's announcement that he will step down from his 15 year position as head of the US National Human Genome Research Institute (NHGRI). Like most comments on Collins's career at NHGRI, the editorial praises the leader for his ambition, political acumen, and emphasis on the ethical implications of genomic research. In addition to leading the Institute to the successful sequencing of the genome in 2003, Collins helped to initiated the International HapMap Project, ENCODE, and the 1,000 Genomes Project. He also lobbied for the passage of GINA (H.R. 493) and was a constant advocate for the inclusion of public outreach and ethics education in genomic research.

Collins's emphasis on the ethical issues and the NHGRI's ELSI program laid the conceptual groundwork that informs much of the work we do here at PredictER. In fact, thanks to the support of The Richard M. Fairbanks Foundation, Inc, the Indiana University Center for Bioethics has been answering Collins's call to address the ethical implications of genetic and genomic research by focusing on both research ethics and medical ethics as the science is translated into current and future predictive health care.

The editorial also mentions some of the challenges that the next director of NHGRI will face. These challenges include a shrinking budget and waning political support:

Although Collins says he has no concrete plans … the future of NHGRI is more cloudy than his own. The funding situation of the NIH has been gloomy for years, with flat budgets stifling many potentially worthy projects. And with Collins gone, the NHGRI may become more of a target for politicians who feel it has run its course.

Of course, the challenges also include existing and unanticipated ethical and legal issues. As the Nature editorial notes: "Genomics is now at a point where the science and technology are moving much faster than society's ability to assimilate and make sense of the information".

One challenge that this editorial does not mention directly, but seems, nevertheless, to be implied by the shrinking public budget, is the fact that much predictive health research will be (and currently is) receiving commercial support. This should not be a surprise. If we want genomic research to result in better personalized medicine, we should expect that the life science industry will invest in the research. At the same time, however, there's no better moment than now to accelerate the investigation of the specific ethical issues of doing commercially supported genomic and predictive health research. For example, here are a few questions that jump to my mind:

Must a research biobank disclose to donors in the informed consent policy that research results may result in commercial products?

Must or should these biobanks share the income from tissue or data sales with donors?

Should pharmacogenomic companies and other patent holders be expected to share financial rewards with research participants or even with the communities to which these participants belong? - J.O.

The Best Predictive Health Ethics Blogs - May 2008

It was a busy month for predictive health news: the president signed GINA, Francis Collins announced his eminent retirement, bloggers reported from important conferences at Case Western and Cold Spring Harbor, and Google announced the debut of Google Health. These events, and others, are reflected in this month's edition of the best blogs on the ethical issues of predictive health.

Are you diseased? Pre-diseased? Potentially diseased? Greg Dahlmann, blog.bioethics.net. 6 May 2008.
In this insightful post, Dahlmann examines how predictive health is changing our concept of disease. When, exactly, does increased risk = illness? Dahlmann writes:

So we're moving from the concept of disease as a state of impaired function to it representing particular sets of probabilities. In the past you were sick when you had a heart attack. Today, you're sick -- or pre-sick, perhaps -- when you have high cholesterol. What about when it's possible to identify constellations of genes that significantly increase your chances of having high cholesterol, or a heart attack. Would that be considered a disease?

Also see Dahlmann's follow up post on "previvors": Blood Matters. Greg Dahlmann, blog.bioethics.net. 11 May 2008.

NHGRI Director Francis Collins to Step Down on August 1. Hsien-Hsien Lei, Eye on DNA. 28 May 2008.
Lei shares the news the Francis Collins will retire from his post this summer and that Alan E. Guttmacher will become acting director. Lei also some thoughts on Collins' book The Language of God.

In All Fairness. Fred Trotter, Fred Trotter: My life and thoughts, often about FOSS in medicine. 23 May 2008.
Following the news coverage on the release of Google Health, Fred Trotter weighs in on the privacy questions. Trotter argues that Google is not a health care provider and is, therefore, not covered by HIPAA. He writes:

Both Google Health and HealthVault are designed to make the process of dissemination of your health information to people you want them to be disseminated to easier. Are they doing that in a secure, privacy respecting way? Excellent question; fodder for further posts. Should they be covered by the same laws that cover your healthcare providers? No.

Workman's Compensation, Stereotypes and GATTACA. Steve Murphy, Gene Sherpas: Personalized Medicine and You. 10 May 2008.
Murphy addresses a few of the potential social consequences of predictive medicine, by examining the following scenario:

Young person goes to 23andME/Navigenics/ETC (They just may add this immediately)....gets predictive testing indicating that he is at a 300 fold increased risk of herniating a disc in his back. Avoids manual labor (plays video games all day) never herniates the disc. Did we do society a service?

23andMe, deCODEme and Navigenics at Cold Spring Harbor. Daniel MacArthur, Genetic Future. 9 May 2008.
MacArthur reports, first hand, from the "Biology of Genomes" meeting at Cold Spring Harbor. In addition to the big players in the consumer genomics movement, the speakers at the event included some ethics and policy experts, like Kathy Hudson from Johns Hopkins. Hudson, MacArthur notes, "responded to the problem of patients being given data of very limited predictive value with a very sensible solution: 'In the absence of demonstrable harm, the default should be to provide the information.'"

Genetic testing ethics - consent forms becoming incomprehensible. Elaine Warburton, Genetics and Health. 7 May 2008.
Warburton covers the Translating ELSI, Ethical Legal Social Implications of Human Genetics Research conference at Case Western University in Cleveland. In this entry she reports on Laura Beskow's comments regarding informed consent and the attitudes and concerns of research participants. Also see Warburton's related coverage of pediatric research ethics discussions at the conference in her post: Genetic Ethics - testing and storing our kids’ DNA. Genetics and Health. 7 May 2008.

The FDA ditches the Declaration of Helsinki. Stuart Rennie, Global Bioethics Blog. 6 May 2008.
Stuart Rennie of Global Bioethics Blog examines the implications of the FDA's decision to abandon the Declaration of Helsinki. While Rennie focuses on the potential impact of this decision on US research overseas, and not specifically on predictive health research, this decision may have far reaching consequences on clinical trials of any sort. Rennie concludes with the following verdict: "the decision would seem to encourage pharmaceutical companies to cut ethical corners when working abroad".

GINA Series: Irrational Bureaucratic Risk Abhorrence [Page 1]. Andrew Yates, Think Gene. 24 May 2008.
This is the first post of a (thus far) four part series on GINA. Each post begins with the introduction:

Recently, President Bush signed GINA, the Genetic Information Nondiscrimination Act, into law. GINA makes it illegal for employers or health insurers to discriminate based on genetics. Virtually the entire genetics community has lauds this legislation, yet few have written why it's wrong that employers and services review objective facts to make decisions. … “It’s not fair…” but why?

The Puzzling Consensus in Favor of the Genetic Information Nondiscrimination Act. Eric Posner, The University of Chicago Law School Faculty Blog. 6 May 2008.
In what may be the most influential post covered in this edition of the best predictive health ethics blogs, Chicago Law professor Eric Posner examines the GINA and asks some compelling questions:

Should the insurance company be permitted to offer the cheap insurance policy only to people who obtain a doctor's certification that a genetic test shows that they belong to the low-risk group? If you think that insurers should be able to discriminate on the basis of visible markers and on the basis of simple doctors' tests for the presence of dangerous diseases, then you should think they should be able to discriminate on the basis of genetic tests. There is no morally relevant distinction between looking at a person's blood for the evidence of infection and looking at his DNA for evidence of susceptibility to a disease. ... The only explanation for the enthusiasm for GINA is that there is an inchoate feeling among people that there is something wrong with the way the insurance market operates.

Medical Genetics Is Not Eugenics. Gabriella Coleman ("biella"), What Sorts of People. 16 May 2008.
Coleman responds to Ruth Cowan’s article in The Chronicle of Higher Education, “Medical Genetics Is Not Eugenics”. Although Cowan sees little value in thinking about the similarities of modern medical genetics and the mid-century eugenics movement, Coleman cautions:

Even if, as [Cowan] rightly states that genetic testing is oriented primarily toward easing human suffering, genetic testing is still entangled with fraught ethical questions about what types of life we value, what is acceptable human life, and what is not—the very sorts of questions central to eugenics.

GINA, The Bad News: Adverse Selection

This is the second post in a series of posts in which I share what I see as the ups and downs of the Genetic Information Nondiscrimination Act of 2008 (GINA or H.R. 493).

Although the legislation will hopefully do much to encourage research and protect predictive health patients, GINA is not all roses. The legislation has numerous critics who have good reasons to be critical. For starters, it sets the stage for adverse selection to occur in the health insurance industry.

Adverse selection happens when an information gap emerges between the beneficiary and the insurer; if the beneficiary knows much more than the insurer, then the insurer is unable to accurately assess the beneficiary’s risk. This information imbalance results in more claims being made than the insurer reasonably predicted. GINA facilitates this phenomenon by allowing beneficiaries access to genetic information, but denying it to insurers. If, for example, a beneficiary finds out from a genetic test that he has a significantly increased risk of developing prostate cancer, he would use that information in deciding whether or not to purchase insurance, but the insurer would be unaware of that increased risk in deciding in which group the individual should be placed, what rate he should be charged, etc.

This is potentially a big problem in the insurance industry, because insurers need to be able to accurately determine risk in order to prevent claims exceeding predicted levels. In the long run, inaccurate risk predictions in the industry will result in rate hikes, and rate hikes will drive healthier participants out of groups. In a the worst case scenario, this could start a downward spiral in the direction of group or insurer insolvency. - Sam Beasley

The Good News: GINA; The Bad News ... ?

A few weeks ago, congress passed the Genetic Information Nondiscrimination Act of 2008 (GINA), a much anticipated piece of legislation, nearly thirteen years in the making. Since the first version of the bill prohibiting genetic discrimination was introduced in Congress in 1995, the legislation has received significant bipartisan support and support from both the Clinton and Bush White Houses. Until recently, however, even in the face of all of that support, just a few members of Congress were able to block the legislation's progress. An agreement has finally been reached, and GINA is now the law of the land; it was signed by President Bush on Wednesday, May 21st.

Regular readers of PredictER Blog know that we have been following GINA; now that it has been signed, it's time to kick the tires and to see what we've got. This is the first of a series of posts in which I share what I see as the ups and downs of this legislation. I'll alternate between the good news and the bad news and conclude with an overall "thumbs up" or "thumbs down". For this post, some good news:

GINA really is a big deal, in the legislative sense. It provides (at least in theory) significant protection from discrimination based upon genetic information in the employment and health insurance contexts. Studies by the NIH and other institutions have revealed that the vast majority of the American public is afraid of being discriminated against in these arenas and believes that it would be wrong for employers and insurers to do so. Furthermore, additional studies have revealed that a significant number of people who would be likely to benefit medically from genetic tests choose to forgo them for fear that they will lose their job, or health care coverage depending upon the results. Along the same lines, many people are choosing not to participate in important research that requires subjects to undergo genetic testing out of fear of discrimination. Clearly, then, GINA should help to allay public apprehensions and to encourage both the pace of research and the practice of personalized medicine.

But … stay tuned for the "bad news". – Sam Beasley
