The Mayo Clinic will sequence the genome for thousands of patients in a major pilot study slated to begin early in 2012 as part of a significant move toward "proactive genomics" and personalized medicine, The Guardian reports.

Doctors can then tap into this information to prescribe the most effective treatment for each individual person with the least amount of side effects. The plunging price tag for genetic tests has, in part, made the pilot study possible, clinic officials said. Story
