only slightly beyond that, 23andme doesn't cover all of the relevant SNPs but it does cover the ones that allow you to infer that you are less likely to respond to p-glycoprotein based drugs like citalopram and paroxetine. You have to export your 23andme raw data and use something like promethease to reprocess the data.
Is it possible to do this kind of thing oneself with 23andme style SNP tests and a google scholar search, or does it involve more than that?
