Since early 2001, a draft of the map of the entire base-pair sequence of human DNA has been generally available to the scientific community, permitting a range of projects that would previously have been unimaginable. Among those projects will be programmatic explorations of the genetic etiology of human disease. That research will facilitate the development of tests that can identify those at risk for a variety of disorders. Innovative therapies based on genetic information can then be designed, which will provide more effective treatments, and perhaps even methods of prevention or cure. In psychiatry, the syndrome that is perhaps most likely to benefit from such research is schizophrenia.
