> Two years ago, US consumers could see more than 240 detailed health and trait reports, including risk factors for heart attack and type 2 diabetes. Then, at the end of 2013, the Food and Drug Administration clamped down. They implied that 23andMe's tests were inaccurate. They also worried that some consumers would misconstrue the risks, seeking out unnecessary treatments and changing their medication regimes withou…

To anybody who has 23&Me results: can you tell me if they are still reporting tongue rolling as a heritable trait on their reports?

Presumably you are aware this is a Myth of Human Genetics?

Yes, I've read that paper, and I read 23&Me's blog post on the trait from 2008 (http://blog.23andme.com/23andme-and-you/tackling-tongue-curl...). They both agree in saying that tongue rolling is not a Mendelian trait, and they both agree there appears to be a heritable component which affects several tongue-shaping traits.

I'm asking because the 23&Me reports don't really include the contextual information to appreciate the subtlety of non-Mendelian traits. If people see this and come to the false conclusion, then they're likely to come to similar false conclusions abotu the parts of the report that touch on actual health-related issues.

I had it done around 2013 or 2014, and yes, that was in the report.

Sorry to pry, but is it possible you could go back and look at the report and give an indication of how strongly it seems to imply the trait is genetic? Does it include any caveats (without following their links to literature)? Otherwise indicate this trait isn't strongly genetically determined?
