What are the elements of the GPS? We need inexpensive whole-genome typing, rapid access to the results, knowledge of the significance of the results in the context of a drug or indication (i.e., valid pharmacogenetic tests), a method for determining the appropriate prescription, and protection of the genetic data from inappropriate use. In other words, we need lower genotyping costs, more research, and appropriate software—all of which are within our means. -From Dr. Mark Ratain's publication "Personalized Medicine: Building the GPS to Take Us There"
