DNA Dilemma on Newsweek

Mary Carmichael at Newsweek had a great series of articles focusing on direct-to-consumer genetic testing. An excerpt:

I’ve been following DTC genetics since 2007, when wide scanning first became available to the public. Since then, a number of writers have gotten wide-scale genetic tests and expounded on the results. Indeed, I sometimes wonder if I’m the last science reporter on earth with virgin genes. (Technical virgin: My doctor gave me a cystic fibrosis carrier test when I was pregnant.) Initially, I put off getting a full-genome scan because I wasn’t sure how useful such a test would be. I had no particular reason to take one, save curiosity. I wouldn’t expect to find anything serious and potentially life-altering like the Huntington’s disease gene in my results, because my family medical history is thankfully rather boring. The data most likely to be medically relevant to me would concern the genetics of common diseases, and at the time, many comprehensive and well-designed studies of those were still getting underway. I decided to wait a few years and see how research progressed. But here I am, three years later, still unsure.
