I thought the DNA analysis being done by these companies wasn't full sequencing, but rather genotyping. Isn't the implication of this less alarming?

- anon1mous 11y agoToday it's genotyping. But if they store the sample they can sequence it once the price goes down.
- zmmmmm 11y agoIt only takes about 20 snps to uniquely identify someone. They genotype to the order of hundreds of thousands of them. As far as identification (and the risks of misidentification) go, it's pretty much just as bad as sequencing.
- chrisprobert 11y agoCorrect - their current v4 chip covers ~602K SNPs and they have > 1 M customers, so you couldn't uniquely identify all of them by genotype. But given the frequency of rare variation in humans, you'd expect to be able to reduce a given genotype to a much smaller set of customers.
