Do I have the right to know my own genetic makeup?

I took a little time yesterday (July 12) to attend a panel discussion on direct to consumer genetic testing at the Genetic Alliance annual conference. Panelists were Sue Friedman, from FORCE; Trish Brown, from DNA Direct; Joanna Mountain, from 23andMe and Sean George, from Navigenics. Francis Collins, Director of the National Human Genome Research Institute, moderated. Once each of the panelists had made their opening remarks, Collins started the discussion by asking why, if personalized genetics is so wonderful, the states of California and New York have issued cease and desist orders to several personalized genetics companies (story). The response was conciliatory, echoing statements on the 23andMe blog (the spittoon):

We agree that this evolving field of personal genomics is in need of proper regulatory oversight. While our mission to provide accurate and contextual information to our customers about their genetic information is aligned with the regulatory mandate to protect the public health, we also want to ensure that efforts to rein in our industry do not hamper the potential benefit of genetic knowledge to our health.

Many relevant issues were brought up, by panel members, or by those in the audience. Can people deal appropriately with uncertainty? Do they understand the relationship between genotype, the environment and phenotype? What about genetic information with predictive value, but about which the consumer can do nothing? The case of APOE was discussed at length.

I do feel that we have a right to obtain information about our own genetic makeup without having to justify ourselves, to a physician, to an insurance company, or to the state of California. I am also skeptical of the perception that "most people are incapable of grasping the relevance of provisional, statistical information." In any case, an enterprise that feeds users with 500,000 bits of information, most of which have no significance, seems more likely to help people understand that genotype is not fate than to have the opposite effect.

Giving people genetic information can be separated from giving them advice, and it seems to me that providing information about genotype should be regulated only to the extent that technical standards are met. This is analogous to surveyors giving me information about the elevation of my house. That information, by itself, is not advice about flood risk, and I would be surprised if surveyors were required to provide accurate assessments of that risk in order to operate, or forbidden from providing consumers with data that a third party judged to be of little value.

The panel helped me to understand the risk of consumer fraud, but, ultimately, I feel, strongly, that I have a right to know my own genetic makeup. Furthermore, I find it insulting to say that consumers are incapable of understanding uncertainty. There is certainly room for regulation, but I hope that my right to pay someone to tell me about my own genes is not infringed. Perhaps it is most important to prevent companies from taking money for tests without providing portable genotype data whose implications can be evaluated by a third party in the light of new information, which could be information about the implications of that specific information, other genetic information that might influence how it is interpreted, or information about the interactions between that bit of genotype and other factors such as one's diet or medical history.
