Where can I purchase an analysis such as that?
I used the service
23 and Me; their main competitor is
deCODEmeUnfortunately they aren't particularly cheap (23andMe is around $500 for the ancestry and health analysis, though you can purchases them individually too). Mine was a Christmas present.
Nor are the services as detailed as one might wish; they look specifically at certain fairly significant genes. 23andMe identified 11 potential disease-causing (or resisting) genetic variations. THere are a lot more than just 11 out there. On the plus side, however, is that as 23andMe develops additional tests, they'll update the status of those who already purchased it. So if in a few months they add a 12 disease gene that they look at, they will update me with if I am at risk or resistant for that. Too note, their health analysis looks at more than just disease risks. But if you want to see your full genome, I'd recommend volunteering for the
Personal Genome Project. If you are selected, it's the cheapest way of documenting your DNA.
