In a novel educational experience, the University of California, Berkeley offered its 5,000 incoming freshmen the opportunity to participate in a voluntary program in which they would be tested for variants of three genes.

The tests were part of a yearly exercise to involve the new students in a common educational experience centered on a theme. In this case the theme was personalized medicine.
