deCODE’s Bankruptcy Signal a False Promise of Genetic Medicine?


Future Shock or Future Letdown?

New York Times reporter and DNA author Nicholas Wade raised an interesting question in his report on the bankruptcy last month of Iceland’s deCODE Genetics, which attempted to make it possible for an ordinary consumer to buy the latest applicable information on the connection between their personal genes and their personal disease risk.
