$999 For a Complete DNA Scan, Worth it?
DoroSurfer writes "ZDNet is reporting that 23andme.com will open its doors on Monday, allowing you to send them a cheek swab and have your DNA analyzed for $999 (plus shipping, of course... ;)). So what's a thousand bucks buy you? They can tell you your ancient ancestry, They can tell you what diseases you're predisposed to, They give you a "Gene Explorer" that allows you to do a search in your genome to find out if you have a certain gene (e.g., you just heard on the news that Gene XYZ has been linked to Alzheimer's Disease)."
This has already been mentioned, except last time the spotlight was on deCODEme by deCODE genetics which offers more details (1m vs. 600k "sites" of the genome) for less ($985 vs. $999).
I'd love to hear about the results, though.
Very much worth it if one is interested in learning about and working to minimize one's genetic risks.
With regard to being 'worth it'. It's also worth noting that despite the article title, this isn't a complete sequence. 23andMe will scan ~550,000 Single nucleotide polymorphisms (SNPs) out of the (roughly) 10 million SNPs humans have, which is again quite different from a complete sequencing of the 3 billion base pairs in human DNA.

People frequently confuse microarray SNP (single nucleotide polymorphism) studies with an actual DNA scan that identifies all 3 billion A,C,T and G bases in the human genome. This $1000 option looks at about 2 million KNOWN sites which vary between people. These mutations are not the ones that actually code for a disease, but because they happen to be NEAR the actual ones that do on the chromosomes, it is assumed that if you have the SNP mutation, you will have the disease-prone variant in your genome as well. The problem with this technique is that it only measures variants that we know about, whereas a true complete DNA scan would be the "gold standard" and provide you with the most detailed information possible. Unfortunately, a true DNA sequencing of this variety runs about $100000.
National Geographic has a project called The Genographic Project that will take your DNA and trace the ancient travels of your ancestry. It costs $100+S&H and your data is stored along with an anonymous code only you know (before you send it in.) Then the group takes all of the data it gets and puts it all together to further their research.
The team behind the project has already collected thousands of samples from people worldwide who have interesting lineages (Indiginous people in xyz area) and found out some REALLY cool stuff.
The $1k thing seems like a privacy nightmare though.
