You might think so given the flurry of company launches in the last few days. These companies promise to help "decode" your genetics (deCODEme). Or reveal vital information about your 23 chromosomes (23andMe). Or help you navigate your personal genomics (Navigenics).
What makes these companies different from older genetic testing companies is that they look at lots of DNA all at once instead of just a single gene. (They aren't looking at all of your DNA-- for that you need to contact Knome who will do this for a mere $349,000.) This means they can look at many different genes and DNA markers at once giving a broader view of the genetic you.
For around $1000, these companies will take this deep look at your DNA and tell you a bit about your ancestry. They will also be able to tell you a bit about your risk for some diseases. And maybe tell you how likely you are to have a child with blue eyes or red hair. They might even find a genetic reason why you hate Brussels sprouts (take that mom!).
Given how little we know right now about our DNA, I am not sure if these results are worth $1000. A little bit of knowledge can be a dangerous thing. And scientists don't know much yet about our DNA.
