New blog post by Dr. Green: “Motivations for personalized genetic testing include explaining — not just predicting”

In a new blog post at the Huffington Post, G2P Director Robert C. Green, MD, MPH describes an interesting finding from the Impact of Personal Genomics (PGen) Study - people pursuing personal genetic testing are not only interested in predicting future health conditions, but in explaining ones they already have. Dr. Green writes:

Not surprisingly, we found that participants with a family history of a particular condition were more interested in their genetic risk results for that condition (compared to other conditions for which they did not have a known family history). This backs up similar findings in previous studies of people with family histories of breast cancer and heart disease.

But here's the really interesting part: Participants were consistently most interested in their genetic risk factors related to the condition that they already have. From the perspective of "predictive" genomics, this makes no sense whatsoever. If you have already been diagnosed with a condition, why would you be especially interested in your risk of getting it?
