The recent double issue of The American Journal of Bioethics (Vol 9 6&7) includes two target articles (followed by open peer commentaries) on the ethical issues of direct-to-consumer (DTC) genomics and social networking.
The issue opens with an editorial by 23&Me's Andro R. Hsu, Joanna L. Mountain, Anne Wojcicki, and Linda Avey: "A pragmatic consideration of ethical issues relating to personal genomics." The editorial offers five points of discussion that the authors find relevant to the discussion of the ethical issues. Facebook users might be surprised to discover that the service is offered as an example of innovative data sharing policies; see point five: "A single data sharing policy cannot fit the needs of all".
The first "target article" reports the result of an attitudes survey about DTC; see: McGuire AL, Diaz CM, Wang T, Hilsenbeck SG. Social networkers' attitudes toward direct-to-consumer personal genome testing. Although the title suggests that "social networkers" are a focus of the article, in reality they are a convenient (or experimental?) survey population--the authors used Zoomerang and Facebook to reach the 1,080 respondents. Of the respondents, 47% reported a pre-existing knowledge of DTC genomics companies like 23&Me, Navigencs, and deCODEme; 6% reported having used one of these services and 64% reported a willingness to use one of the services in the future.
The second "target article" focuses on where all this might be leading; see: Lee SS, Crawley L. Research 2.0: social networking and direct-to-consumer (DTC) genomics. In addition to proposing that social network analysis could be used to explore the impact of these DTC genomics ventures on research, data sharing, and subject recruitment, the authors also ask: "What are the ethical and social implications of new social formations created through the sharing of personal genomic information?" In other words, how will the convergence of Web 2.0 and personal genomic information (PGI) change our social structures?
Commentaries on these articles include a few authored by friends of the PredictER program; see, for example:

What's in Steve Jobs's Genome? Genetic Information at the Top
Jacob Goldstein of The Wall Street Journal's Health Blog asks "Do Apple Investors Have Right to Steve Jobs's Health Info?" -- Investing is a gamble and gamblers need good information to make the best bets. Publicly traded companies are required (with varied levels of success) by the SEC to be transparent with their books. So, if you're thinking about investing in a company with a very charismatic CEO, you might want to know about the results of his most recent physical exam. As genomic medicine improves one could imagine a future in which "reasonable" investors demand a genome profile too. Goldstein observes that Jobs is both a "swashbuckling entrepreneur" and a pancreatic cancer survivor. I'm unsure how that information would help an investor and I'm fairly certain the science of reading the genomic tea leaves would not be much help, at least not yet.

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.

Dr Watson's Genetic Counselor: Witty or Insulting?
Today's issue of Nature [subscription required] includes a letter responding to Wheeler DA, et al. The complete genome of an individual by massively parallel DNA sequencing. Nature 452, 872-876 (17 April 2008) | doi:10.1038/nature06884. The author of the response, a genetic counselor, lifts a layer off the science publishing hype that surrounds anything about the human genome in this era. Also see the very insightful and witty table comparing two potential personal genome and genetic counseling clients: "Dr. Watson" and a "lay patient".
Here's a sample:
- Dr. Watson: Thinks the $1 million cost is a good deal - Lay Patient: Worried about the cost of a - consultation
- Dr. Watson: Brings in sequence data on a hard drive - Lay Patient: Brings in records about sinus infections
- Dr. Watson: Chose to have Apo-E sequence redacted - Lay Patient: Expects to learn blood type
- Dr. Watson: Shares 1.68 million SNPs with Craig Venter - Lay Patient: Googles SNPs to find out who they are
Well said! But gee, the "lay patient" must be a real dimwit ... if I ever need a genetic counselor, I'm going to do my homework first! - J.O.

Navigenics Enters Personal Genomics Game ... Meanwhile: "What's a SNP?"
On April 8th, Navigenics announced it will provide genomic testing services to the general public, yet, creating additional competition among other genetic health startup companies such as deCODEme and 23andMe. These businesses are drawing attention by allowing ordinary people to see their genetic makeup and by providing services to help understand their risk for common conditions.
For an initial fee of $2500, Navigenics’ personalized medicine package includes genotyping for 18 listed medical conditions such as Alzheimer’s disease, glaucoma, colon cancer, lupus, breast cancer, prostate cancer, and Crohn’s disease. Saliva, instead of blood, is collected for the genome scan as a less invasive and less hazardous approach. Within three weeks, Navigenics promises to deliver your risk assessment report electronically and provides genetic counseling over the telephone to educate customers on their genetic predispositions and to encourage them to take preventive measures.
The personal genomics industry is growing and potential consumers have choices. For example, 23andMe lets customers see their entire genetic profile of more than 500,000 single nucleotide polymorphisms (SNPs) while Navigenics limits customers to 18 selected conditions, even though it uses a 1 million SNP chip. On the other hand, Navigenics promises the customer access to future technology for an annual fee of $250. Customers’ spit samples are frozen, stored, and re-tested as new associations with SNPs are found.
Hoping to set industry standards, Navigenics proposed 10 criteria for performance, quality, and service for personal genomic services:
1. Validity
2. Accuracy and quality
3. Clinical relevance
4. Actionability
5. Access to genetic counseling
6. Security and Privacy
7. Ownership of genetic information
8. Physician education and engagement
9. Transparency
10. Measurement
With the evolution of personalized medicine and genetic profiling, consumers have more information in their hands. New research initiatives are on the move to understand how consumers act upon this information (i.e. ignore health risks or needlessly worry about slight risks). Navigenics has plans to support future health outcome studies and has recently joined forces with the Mayo Clinic to measure the impact genetic information has on behaviors.
It will be interesting to see whether The Personalized Medicine Coalition adopts or modifies Navigenics standards. Also interesting will be the response from the medical community to risk assessment reports generated by personal genomic businesses such as Navigenics, 23andMe, and deCODEme.
What could be better than knowing your own DNA? This genomic revolution sounds almost too good to be true. Dr. Eric Topol, cardiologist at the Scripps Clinic (ironically a collaborator with Navigenics), listed his comments (December 2007) in an editorial for The Wall Street Journal. Topol presumes it is too soon to tell whether having your genome scanned can be good for your health because there are so many unidentified genes associated with disease risk. He also wonders, as do I, how personal genomics will impact the medical community. His example . . . "When a consumer arrives in his or her doctor’s office to get help in interpreting the genomic data, the doctor is likely to respond: What’s a SNP?" – Katie Carr

Gene Sherpas for CME
Steve Murphy at Gene Sherpas: Personalized Medicine and You has often asserted that physicians will need continuing medical education to understand the latest advances in genetic research and to interpret clinical genetic information. In a recent post, however, he provides a few hints about what he will be doing to make these educational opportunities a reality. Murphy writes:
There is a new hope. An institution being set up by myself and others. We are currently looking for donors and we endeavor to set up educational events and group sessions. We will work with Corporate Genomics, Academic Genetics, Corporate Labs, Academic Medicine to develop training workshops. Interested?
Well Steve, I'm interested (obviously), PredictER has been working on continuing medical education programs for physicians with patients participating in genetic research. We have made plans to offer two initial programs in local clinics here in Indianapolis this summer—we hope to stream these programs to a wider audience as well. While this is one step removed from the clinical use of consumer genomics (we're really focusing on research ethics in the clinic), I hope that our work on the ethical issues of genetic medicine will be of use to your hoped for institution. At the very least, don't forget the ethicists and community advocates when designing your curriculum. Good luck finding donors and keep us posted! – J.O.

Genetic Research and Mental Health: Some Ethical Issues
On Monday, March 17, two Indiana University mental health researchers, Dr. John I. Nurnberger and Dr. Alexander B. Niculescu III, addressed the weekly PredictER meeting at the IU Center for Bioethics in a talk entitled: “Genome-Wide Association Studies: What Have We Learned So Far". Dr. Nurnberger is the current director of the Institute of Psychiatric Research at the IU School of Medicine and Dr. Niculescu is Assistant Professor of Psychiatry and the Director of the Laboratory of Neurophenomics. Niculescu, Nurnberger and others recently published a widely discussed [see Steve Mitchell, MSNBC, 25 Feb. 2008] blood biomarkers for mood disorders study [PMID 18301394 - PDF].
Current Challenges in Understanding and Treating Mental Health Disorders
Dr. Nurnberger (who chaired the first portion of the lecture) began the talk by outlining the prevalence of various neuropsychiatric disorders, focusing especially on Bipolar disorder. Dr. Nurnberger's discussion was supplemented by an explanation from Dr. Niculescu of some of the shortcomings that past attempts to understand the genetic links to depressive/Bipolar disorders have had. According to Dr. Niculescu, “Until recently, the lack of concerted integration between the two approaches [has]… constituted a missed opportunity to accelerate our understanding of this complex and heterogeneous group of disorders”. Simply put, mood disorders involve many, many genes, which may be present in various combinations in any one of us, and interact in ways that defy easy classification. While it is clear that individuals with certain psychiatric disorders may have certain combination more often, we are far from understanding precisely which genes are responsible for which portions of the disorders.
Dr. Niculescu then detailed two main “arms” of his research; the first involves an innovative response to the problem of how to create a sophisticated working picture of the genomics involved in mental illness. Using a technique called Convergent Functional Genomics (CFG), Dr. Niculescu's team brings data from three sources together - animal model gene expression data, human genetic linkage/association data, and finally human tissue (postmortem brain, blood) data.
The advantages of bringing these there sources of information together are manifold. Dr. Niculescu’s team has been able to cross-validate findings from other research studies. This has helped his team to “extract meaning from large datasets" and to prioritize "candidate genes, pathways and mechanisms for subsequent targeted, hypothesis-driven research”. Furthermore, as Dr. Niculescu indicates, this convergent functional genomics approach may help to deliver on one of the most exciting and elusive goals of genetic research in the area of mental health: a blood test that could identify blood biomarkers of an illness.
“PhenoChipping” and the Move Towards More Individualized Mental Health Care
As part of working towards this goal, Dr. Niculescu’s research team is implementing another innovative approach – the use of PhenoChipping. In layterms, a gene is thought to be like a “blueprint” for how something biological is built; a phenotype is the way that thing is actually built and lives, which may diverge from the plan, or may change over time according to its environment. “PhenoChipping”, thus, refers to the process of collecting mental health data from subjects using a massive inventory of cognitive and affective tools. Researchers are hoping to combine this “in vivo” data with advanced genomic data to better understand what complex interaction of genes, environments, stress, and other factors participate in these serious and highly complex neuropsychiatric disorders.
Dr. Niculescu and his team see their research as moving towards the development and implementation of more tailored, personalized treatments in psychiatry. In this more personalized medicine the patient's unique profile is the target of therapeutic interventions. Dr. Niculescu states: "We hope our work will contribute to better diagnostics, early intervention and prevention efforts, and more efficacious treatments, with reduced side-effects".
Some Ethical Questions:
This research is a rich playing field for bioethics with its intersection of illness, consent, duress, technology, and research whose implications (and even direction ) can barely be anticipated from where we stand. Some questions to consider are:
What are the ethical issues to be considered when conducting research on populations of people that are ill, and ill in a way that affects judgment?
What does consent to mental illness research mean in the absence of a cure?
What if we were able to develop a blood test that help predictive capacity for determining if someone was at risk of developing a mood disorder? What would individuals want to know, and under what circumstances?
In what ways would the ethics of this predictive, diagnostic power mimic existing models in the ethics of disclosure of illness? How, for example, would it differ from existing ethical frameworks for disclosing HIV status, terminal illness, and other conditions?
What does participation in long-term mental health genomic studies mean for participants? Can participants “withdraw” from research, and if so, what happens to their data?

Predictive Health: Best Ethics Blogs - February 2008
This second, monthly installment (see January's Best Ethics Blogs) includes blogs on the ethical issues of biobanking, the risks of genetic testing and discrimination, responses to a recent New York Times article, and thoughts about Google Health and HIPAA compliance. Entries are listed below by topic and date.
Biobanks
Biobanking, part 3: returning research results to participants. Sue Trinidad, Women's Bioethics Blog. 4 February 2008.
Continuing her excellent series on biobanking, Sue Trinidad, asks readers to consider the following scenario: "Let's say that--20 years after you consented to participate in a breast cancer study--researchers working on a different project discover that you carry a genetic mutation that has been definitively linked to Serious Medical Problem X. ... Do the researchers have a professional and/or moral obligation to share this information with you?"
More on BioBanking. Sue Trinidad, Women's Bioethics Blog. 6 February 2008.
In a fourth post on biobanking, Trinidad responds to a BBC News story ("Change planned on cloning consent", 2 February 2008). The story reports that the UK government may allow the use of tissues donated for research for embryonic cloning without requiring the explicit consent of donors. Sue asks: "[J]ust what should be the scope of allowed activities under a 'blanket' or 'one-time' consent? Also, should the research imperative (and perhaps the common good) outweigh individuals' preferences in such cases?"

Consumer Genetics
While The DNA Network provides a constant stream of quality blogs on the ups and downs, ins and outs of direct-to-consumer, genetic medicine, two caught my attention this month for demonstrating creativity and gumption.
Polls Closed, Myriad Tallies Up and We await Navagenics! Steve Murphy, Gene Sherpas: Personalized Medicine and You. 11 February 2008.
In an informal survey of his readers, Murphy discovers that most think 23andMe is the most likely to be sued first. In assessing the litigious environment, the Sherpa (Murphy's pithy alter-ego) comments: "If I had a law degree … I would bone up on genetics legal precedent, corporate protections and genetic discrimination. If you think a certain ex-candidate for president made a bundle suing OB/Gyns, you haven't seen the beginning of the legal fortune to be made in genomics."
DNA Videos: Genetic Testing on NBC Nightly News. Hsien-Hsien Lei, Eye on DNA. 13 February 2008.
In this post Lei embeds videos from the Robert Bazell NBC Nightly News series "The Truth About DNA". One of these features Stanford's Hank Greely, who expresses his worries about the genetic testing market place. In a follow-up blog post, Bazell laments a "frightening lack of government regulations". After wondering if Greely and Bazell are "easily scared", Lei takes the advice of a genetic counselor (Ellen Matloff) and writes a sample letter for "Johnny" to open a discussion of his genetic test results with his family members. Will his parents be surprised to discover that he blames them for everything? Maybe someone should persuade Johnny's "parents" to write a reply.
Discrimination
Q&A with MDV’s Bill Ericson: On PacBio’s origin, why Gattaca isn’t our future, and throwing out your statins. David P Hamilton, VentureBeat: Life Sciences. 15 February 2008.
In this interview with Bill Ericson of Mohr Davidow Ventures, Hamilton asks: "What about the potential downsides, such as genetic discrimination that could leave many people uninsurable, or even the possibility that society could end up stratified by genetic caste, as in the movie Gattaca?" Ericson responds, in part, "I worried a lot about those negative implications when we started investing, but American society is, I think, mature enough to deal with the information, whether by legislation or via general social norms."
Rewarding Ignorance. Doug Masson, Masson's Blog – A Citizen's Guide to Indiana. 24 February 2008.
Doug Masson was among the many bloggers (including Steve Murphy and Sue Trinidad) responding to Amy Harmon's New York Times article "Insurance Fears Lead Many to Shun DNA Tests" (24 February 2008). After describing how the insurance industry needs a degree of "ignorance" to survive, Masson observes: "as our knowledge of a person’s likely health care profile increases, paying for medical treatment becomes less about managing risk through insurance and more about determining what our obligations might be toward our fellow humans in subsidizing their ability to live and/or remain healthy".
Bipolar Blood Test? Let The Bloodbath Begin. Philip Dawdy, Furious Seasons. 28 February 2008.
Dawdy, a patient, reacts to the latest research news about the search for psychiatric biomarkers. Research at Indiana University School of Medicine has isolated blood markers to identify mood disorders. Lead author, Alexander B. Niculescu III, M.D., Ph.D. (a future guest at our weekly PredictER meeting), hailed the research as "a major step towards bringing psychiatry on par with other medical specialties that have diagnostic tools to measure disease states and the effectiveness of treatments". If, however, a test is developed, Dawdy declares, "I am going nowhere near that test because its results--unless you do the test privately--will follow me the rest of my life and be used to discriminate against me and people like me in insurance (health and life), employment, schools, housing and God knows what all".
Health IT and Medical Records
Of Slelling and Men. Steve Murphy, Gene Sherpas: Personalized Medicine and You. 3 February 2008.
After defining "slelling" and recounting the scandals that have limited the possibility of selling health data without the explicit consent of patients, Murphy cites Emanuel EJ, Wendler D, and Grady C (2000) to summarize how "ethicists feel" about data acquisition in clinical research.
Engineering Grand Challenges – Advancing health informatics. Deepak Singh, bbgm. 19 February 2008.
In reviewing an article published on the National Academy of Engineering website, Deepak Singh notes that the technological challenges of health informatics are inseparable from some common ethical concerns. Singh's notes that "[w]hile the article refers to privacy and security, it does not address the issues of content ownership and data portability". Among the questions the Singh would like to see answered are: "Who owns someones medical data? How does it move from one system to another? What parts can a physician have access to? [And] what are the dangers of a system controlled by the user … [?]"
Google PHR roll-out: how personal will a personal health record be? David Harlow, HealthBlawg. 24 February 2008.
Although any news about Google's developing personal health records platform "Google Health" results in an avalanche of blog posts, David Harlow was among the rare bloggers to recognize and speculate about the medical research potential of these records. In reflecting on the privacy and HIPAA challenges that Google's personal health records may bring, Harlow remarks:
So let's assume the worst: Google will sell ads to the highest bidders for keywords in your PHR (kinda OK so long as there's adequate disclosure up front), will sell aggregated de-identified data for population-based health studies (ditto, but this seems more like a good thing, and is really at the heart of the value of EHRs and PHRs generally -- though the utility depends on how much data really finds its way into the PHR, and how it's organized) and worst of all, will mistakenly convert your PHR into an RSS feed that ends up on every computer in America (eek! . . . but is that worse than dropping a paper record behind a file cabinet and never finding it again?) … Every innovation comes with a set of benefits and burdens.
Politics
One gene, two genes; red genes, blue genes. Jesse Reynolds, Biopolitical Times. 14 February 2008.
Reynolds responds to an article published in New Scientist, "Two tribes: Are your genes left-wing or right-wing?" (2 February 2008). Following a critical assessment of the media coverage and a skeptical review of efforts to study the genetics of political attitudes and behavior, Reynolds identifies a potential "disturbing" social implication for such research: "accepting that genes determine political orientation could cause deepening political apathy … Heck, why bother voting when you could just have your cheek swabbed?"
Biobanks
Biobanking, part 3: returning research results to participants. Sue Trinidad, Women's Bioethics Blog. 4 February 2008.
Continuing her excellent series on biobanking, Sue Trinidad, asks readers to consider the following scenario: "Let's say that--20 years after you consented to participate in a breast cancer study--researchers working on a different project discover that you carry a genetic mutation that has been definitively linked to Serious Medical Problem X. ... Do the researchers have a professional and/or moral obligation to share this information with you?"

Predictive Health: Best Ethics Blogs - January 2008
This is the first in a series of monthly posts in which I share some of my favorite posts on the ethical, legal and social issues of predictive health research and medicine. A public and open discussion of these issues will increase the likelihood that individuals and communities will realize the benefits of advances in genetic and personalized medicine, human genome sequencing, predictive neuroimaging, biobanking, and health IT. PredictER Blog commends the following blogs for doing their part to inform and foster dialogue.
Listed by Topic and Date:
Biobanks
Biobanking and you. Sue Trinidad, Women's Bioethics Blog. 19 January 2008.
In the one of the first of what I hope will be long series, Sue Trinidad asks good questions about informed consent and reminds us that even "anonymized" DNA samples might be identifiers. She writes: "nothing is a more precise identifier of who you are than your so-called genetic fingerprint. Is this worrisome?"
Should genetic researchers be able to share your DNA? Sue Trinidad, Women's Bioethics Blog. 23 January 2008.
In her second post on ethical issues of genetic research and biobanks, Trinidad adds additional compelling questions, including: "If you'd consented to participate in that study at your local research university, how would you feel about your (de-identified) information being used by researchers somewhere else?" and "Say the researchers did [a] breast cancer study, and in the course of that work they noticed that there seemed to be a correlation between certain genetic patterns and alcoholism or schizophrenia. Would it be ok with you for them to pursue this line of inquiry using your genetic information?"
Consumer Genomics
American Society of Human Genetics (ASHG) Statement on Direct-to-Consumer Genetic Testing. Hsien-Hsien Lei, Eye on DNA. 2 January 2008.
Getting the month off to a good start, Hsien-Hsien Lei reviews the ASHG's policy statement [PMID: 18055737 excerpt] on Direct-to-Consumer Genetic Testing. Lei makes the following observation:"With increased competition in the field of direct-to-consumer personal genomics in 2008, I predict that only companies that can fully address the [ASHG] recommendations ... will survive .... Consumers are getting up to speed on what genetic testing can offer them and won’t settle for fuzzy, incomplete information."
Also see Lei's related posts on the subject, including: "The New England Journal of Medicine Gives Direct-to-Consumer Genome Scans Thumbs Down" (Eye on DNA, 10 January 2008).
Do I need a personal trainer or a personal genetic counsellor? Myles Axton, Free Association. 11 January 2008.In the editor's blog of the journal Nature Genetics, Myles Axton reviews the NEJM editorial “Letting the Genome out of the Bottle--will we get our wish?” (Hunter DJ, Khoury MJ, Drazen JM. N Engl J Med 2008; 358 (2):105-7. PMID:18184955 excerpt) Axton appreciates the skepticism and applauds "efforts to build genetics into every stage of medical education", but adds: "The authors have some good points, but largely ignore the unpredictable motivational potential inherent in handing people their genomes and asking them to participate in finding out more about their variation and phenotypes. Sometimes, the best doctor will say “we don’t know yet, let’s find out together”.
Privacy Issues
Your personal health: The internet and privacy. Deepak Singh, businessbytesgenesmolecules (bbgm). 2 January 2008.
Singh compares the success of Web 2.0, which relies, in part on "the forfeiture of privacy" to the rise of consumer genomics. Singh writes: "the moment you leave your footprint online, you are giving away some of your privacy. The moment you sign up for a genomic service, you are giving away some of your privacy. The question we need to answer is a simple one in a way. Is the benefit we get from being online, or getting yourself genotyped, worth the loss of privacy?" Singh has obviously traded some of his privacy for the benefits of Web 2.0; will he do the same for consumer genomics?
Respecting patient privacy preferences. John D. Halamka, Life as a Healthcare CIO. 21 January 2008.
Halamka is Chief Information Officer of CareGroup Health System and Harvard Medical School, a practicing Emergency Physician, a participant in the Personal Genome Project, and (among many more things) a vegan. Halamka writes: "One of the greatest challenges for healthcare information exchanges is to ensure continuity of care for patients while also respecting patient privacy preferences." He envisions a future in which electronic consent wizard will support a truly itemized process for sharing personal medical records and health data. Patients and research participants, might provide very specific consent statements, for example: "If I'm unconscious in an emergency room, share everything including mental health, substance abuse and HIV status data. If I'm visiting a Minuteclinic do not include my mental health and substance abuse history. If I'm sharing my data for a population-based research study, do not include my HIV status."
Whole Genome Sequencing
The ethical challenges of whole-genome sequencing part 1. Daniel MacArthur, Genetic Future. 22 January 2008.
In the first of a two(?) part post reviewing "Research ethics and the challenge of whole-genome sequencing" (McGuire AL, Caulfield T, Cho MK. Nat Rev Genet 2008; 9 (2):152-6. PMID:18087293), MacArthur summarizes advances in whole-genome sequencing technologies and evaluates the authors' comments on: the return of genome data to participants, the provision of clinical follow-up, and the integration of genome data and medical records. If you've read the NRG commentary, you'll be interested in this post; if you don't have a subscription to journal, you'll value MacArthur's outline of the issues. In his forthcoming part 2, MacArthur plans to "discuss the other major ethical challenges discussed in the NRG commentary: obligations to close relatives of study participants, and future uses of samples and data." Stay tuned! -J.O.

Genealogy, Genetic Medicine and Getting the Story Straight
What is the promise of personalized medicine and predictive health? Here's a rough description: physicians will know more about individual patients and will therefore be better equipped to provide care. But will it be so simple? In any field, the acquisition of more information, even accurate information, does not necessarily lead to successful application. So, let's say we all buy a test from 23andMe or deCode or Navigenics or any of the growing list of direct-to-consumer genomics company ... and we unpack every last bit and byte of our genetic data, will the world be a healthier place? Or, let's say, just a few of us fork over the $1000 to have our genomic fortunes told … are we really ready for the complications that this information may bring?
If the practice of genetic genealogy is any indication, the future of medicine in the genomic era will be suffused with complications. Nancy Berlinger, of Bioethics Forum, provides an engaging and insightful account of a few of these in "And I am Marie of Romania: Genetics, Genealogy, and the Ethics of Storytelling". Berlinger adds to the ongoing commentary on the new Henry Louis Gates, Jr. venture, AfricanDNA. Gates started this venture, in part, because of frustrations with inaccurate and misleading genetic genealogy results. As Berlinger writes, the misinterpretation (that Gates possesses a genetic link to those once living in the ancient North African kingdom of Nubia, and not, as it turns out, to a less impressive European "servant" in the American colonies) might have been the result of poor science, but also, might be attributed to "wish fulfillment on the part of geneticists and their clients".
To the Gates story, Berlinger contributes related accounts of individuals receiving, accurate, but potentially unwelcome, genealogical information. While America still struggles with its racist inheritance, individuals like Bliss Broyard struggle with new found genealogical information (see her new memoir, One Drop: My Father’s Hidden Life — A Story of Race and Family Secrets). Every one has family secrets--information we are not privy to at the moment--and (as Matt Mealiffe reminds us in Who's Your Daddy?) there's no reason to believe that all or even most of these secrets are about race. Clearly, genetic genealogy (as Blaine Bettinger often notes) is no simple task--will personalized, genetic medicine be any easier? Who will hold and who will expose the secrets in your genome? Is it possible, just maybe, that a one or two of the most enthusiastic, early adopters of personalized medicine will discover a few things they'll wish they'd never known? - J.O.
