Trends Update — DTC Genetic Tests: NOVA ScienceNOW Program Takes a Look

B&W_DNA_sequenceYesterday’s NOVA ScienceNOW program included a segment on direct-to-consumer genomics (H/T to GenomeWeb’s Daily Scan Blog).  The program was bullish on George Church’s Personal Genome Project; but it took a pretty dim view of the predictive value of current consumer technology.

The program was accessible and interesting, but it went overboard in making a cautionary point about current DTC genomics offerings.  It transitions directly from Neal deGrasse Tyson’s 23andMe results for heart disease and diabetes to Steven Pinker’s genomic scan, which showed that Pinker had “double the risk of baldness,” whereas Steven is anything but bald.  Well, sure, and the weather report yesterday said there was an 80% chance of rain but it didn’t rain.  That doesn’t mean I should stop checking weather reports, or even that I was stupid to pack an umbrella.  It’s just probabilities.  I guess I agree with the program in the sense that anyone who can’t spot that flaw shouldn’t be interpreting their own genomic data, but it seems like an oddly condescending way for them to make the point.

Kudos, though, for pointing out:

  1. the gaps in the Genetic Information Nondiscrimination Act; and 
  2. the low risk to tenured Harvard profs of revealing their sequence data, as they are likely shielded from many of the risks to other participants.
