> I use 23andme and I'm happy with the information provided. I know it's not reliable - it's not a lab test anyone will use to base important decisions on, since it is not a full sequence of genes. You have unwittingly affirmed the very argument you are attempting to refute. Their inability to make accurate functional predictions from genomic data has much less to do with the technology (sequence vs. array) than it does with the fact that, isolated instances aside, nobody knows how to do this well. I am a 23andMe user myself and, knowing a bit about statistical genomics, I was surprised how credulously the results of one or two GWAS papers are presented as an almost-diagnosis on their website. GWAS are plagued by all sorts of confounding issues and the statistical evidence in favor of their conclusions is often extremely weak. This is not something that the general public appreciates, so I can see why FDA might get involved.
