Steve, here is a note I sent to the FDA a week or two ago.
I am writing to comment on the meeting to be held March 8-9 about direct to consumer (DTC) genetic testing (Docket FDA-2011-N-0066). I am especially motivated to write after reading the plea to you by the AMA that any DTC results of possible medical interest be censored to consumers. Their letter reflects an appalling paternalistic arrogance that would violate basic freedoms and impede public scientific understanding. I presume that if they could they would have you ban bathroom scales on the grounds that body weight must only be revealed in consultation with a "qualified medical professional."
The AMA submission has two main themes. The first is that citizens are unable to understand the risks and predicted outcomes that might be reported and that experts are vital to provide guidance. My own experience is that I am perfectly capable of finding empirical risks from current literature, I expect I can do a much better and more thorough job than my personal physician, and even my teenage son can do it with no trouble. My own experience, again, is that only about 1 in 5 medical students know what Bayes` Theorem is.
The second theme is that knowledge of potentially medically relevant genotypes can do some unspecified harm to customers. I have spent a total of six or so years on university IRBs, and this kind of worry is ever present. While there is much public loose talk about psychological harm and the like, within the committee room we all understand that the practice of witholding any data from subjects about themselves is nothing but protection from lawyers. I am perfectly free to refuse to participate in research and in clinical trials but I am not free to refuse to participate in federal censorship of knowledge of my own genotype.
I would urge you to keep freedom of information for consumers at the center of the table when you discuss regulation of the DTC genetic testing industry."
