The use of GWAS data to infer global ancestry is quite entertaining, and I'm glad that the author shared so much about 23andme's results with us.<p>Still, I have the urge to mention this everytime I see 23andme, so apologies in advance. Your genetic profile is currently less useful than a proper history and physical exam (but mostly just history) in predicting risk for the vast majority of diseases.<p>This may change, but the extent to which the GWAS data from 23andme will be useful for imputation of the (as yet undiscovered) causal variants that we'll be discovering in the near future is currently unclear.<p>So in the meantime, enjoy every aspect of their services, but I would encourage you to put little emphasis on their disease predictions. The fact that you don't have one of the known breast cancer mutations doesn't mean that you don't have a novel one. The fact that you are predicted to have high risk of heart disease doesn't mean that you don't have a novel cardioprotective allele elsewhere. At some point in the near future, genetic data will be really useful for risk prediction. We're not quite there yet with the GWAS data that 23andme uses (<i>EDIT</i> or any GWAS data - this is no knock on 23andme).
You should also use Promethease which automatically links your raw data to the snpedia data to product a really long report of various traits and research results.<p><a href="http://www.snpedia.com/index.php/Promethease" rel="nofollow">http://www.snpedia.com/index.php/Promethease</a><p>It's a bit messy and hard to interpret but you get a lot more the info that 23andme provides.

I run a DNA test in 2005. I'm chilean and have british ancestors and I wanted to find out what was my origin (English, Scottish, Irish). A Carpenter 'cousin' from USA told me about DNA for Genealogy and bought me a DNA kit from Family Tree DNA <a href="http://www.familytreedna.com" rel="nofollow">http://www.familytreedna.com</a><p>I didn't match any Carpenter from USA but a lot of people from UK and USA. Genealogy is a fascinating hobby.
I got my results about 20 minutes ago. (I should have got it a few weeks ago, but DC post office screwed up delivery of the spit kit.) I assume a lot of other people on HN have gotten results recently: <a href="http://news.ycombinator.com/item?id=1288125" rel="nofollow">http://news.ycombinator.com/item?id=1288125</a>
