In my previous post I quoted from Mary Carmichael's excellent interview with two officials from the FDA, Alberto Gutierrez and Elizabeth Mansfield (part of her fantastic week-long DNA dilemma series, which you should read in full if you haven't already). There are numerous nuggets of gold tucked away in this interview that warrant further analysis, and I wanted to highlight a few in more detail. For a more complete dissection I'd recommend Keith Grimaldi's post commenting on the whole interview.
I wanted to focus on two crucial tidbits unearthed by Carmichael: the attitude of the FDA towards the release of raw genetic data, and the context for horrendous scare-mongering quotes used by Gutierrez in previous mainstream media articles about direct-to-consumer genetic testing.
The FDA says accessing raw genetic data should not be regulated
This is great news for those of us interested in ensuring that people who wish to explore their own genome can do so without excessive bureaucratic intervention:
In other words, the FDA has stated on the record that if a company offers to sell you your genome sequence without interpretation, they can do so without FDA intervention. And if you then wish to take that genome sequence and run it through any of the growing list of open-access tools for interpretation (such as Promethease), you're free to do so; many of these are fortunately hosted well beyond the reach of the FDA.
Gutierrez confirms that his horror story about ovary removal wasn't due to a direct-to-consumer genetic test
Alberto Gutierrez has repeated an anecdote about women removing ovaries following test results in at least two separate mainstream media articles, both of which were written primarily about direct-to-consumer companies. The implication of Gutierrez's quotes was thus that these incidents were a result of DTC tests. Here's the first example, in a story by Andrew Pollack in the New York Times:
And again, in Rob Stein's piece in the Washington Post (which is also problematic for other reasons):
Neither of the reporters writing these two stories bothered to seek clarification about the details behind these anecdotes - for instance, whether they were actually due to tests offered directly to consumers. Now Carmichael has asked that question, and the answer is illuminating:
So now we know - the alarming stories were not a result of direct-to-consumer genetic testing. Indeed, neither of these examples are about predictive genetic tests at all - both OvaSure and OvaCheck are based on the use of protein biomarkers in blood to identify the presence of ovarian cancer - and yet both Rob Stein and Andrew Pollack inserted Gutierrez's quotes into stories that otherwise referred almost exclusively to direct-to-consumer genetic testing.
Whether this was due to a lack of context provided by Gutierrez, or simply sloppy reporting by Stein and Pollack, is currently unclear. Either way, it was inexcusable - and given both stories emerged at a time when the media and regulators were hunting for excuses to criticise the DTC genetic testing industry, there's little question that these out-of-context quotes had an impact.The DTC genetic testing industry needs change: a purging of the companies operating at the disreputable end of the spectrum, and a general tightening of operating practices to ensure that raw data are accurate and that customers are given appropriate information to interpret their results. This change should be brought about by careful, light-touch regulation commensurate with the actual level of risk posed by these tests - which is very little, according to the data currently available. What is not needed is shameless scare-mongering by regulators and reporters seeking to make a splash.Serious kudos to Mary Carmichael for asking the hard questions, and getting some real answers - no easy task when your subjects are FDA bureaucrats.
