Oversold as in "a genetic test will tell you how and when you will die"? True. But what we are doing today: telling people if they should take drug A, B or C, based on their mutations. Telling people if the fetus is affected by any of a pool of diseases. Pointing clinicians towards diagnostics (i.e. adding info, removing hypothesis...). Tracing diseases in genealogic trees and counselling future parents. Lots and lots of other goodies that were not available 10 years ago. And the best part is that there are much to come.
