Laura Hercher, MS, CGC did a wonderful job summarizing some of the main points of discussion at the two-day workshop on direct-to-consumer (DTC) genetic testing, which was co-sponsored by the Institute of Medicine and the National Academy of Science at The DNA Exchange (http://dnaexchange.wordpress.com/2009/09/04/dc-takes-on-dtc-the-t-doesnt-stand-for-tomorrow-anymore/).
As a follow-up, I would like to touch upon a point to which the represented DTC companies alluded a few times, as did some of the speakers: the use of direct-to-consumer genetic test results as an effective motivator for lifestyle change.
Most health professionals probably agree that there is limited clinical utility to most single nucleotide polymorphism (SNP) tests at this time. At most, they may argue, test results are informational but not medically relevant.
However, as DTC companies and other groups race to validate these SNPs as a better (or at least appropriate) indicator for multifactorial disease, I also wonder whether test results will also motivate individuals to make healthier choices and engage in proactive, preventative medicine.
