pills_x220Last year, when more than 100 of the world’s top geneticists, technologists, and clinicians converged on Cold Spring Harbor Laboratory in New York for the first annual Personal-Genomes conference, the main focus was James Watson‘s genome. The codiscoverer of the structure of DNA was the first to have his genome sequenced and published (aside from Craig Venter, who used his own DNA for the private arm of the human genome project.) Watson sat in the front row of the lecture hall as scientists presented their analysis of his genome. They paid special attention to the number of single-letter variations or small insertions and deletions in his DNA–clues as to whether he had a genetic variation that slightly boosted his risk for heart disease or cancer. But there was very little usable information in the genome…A Turning Point for Personal Genomes
