In psychiatric genetics, we are at the end of the beginning, not the beginning of the end. Remarkably, in a field characterized by a checkered history and few confident etiological clues, the genetics knowledge base has advanced considerably during the past five years, and results to date contain clear indications that further study will yield greater insight. Elucidation of the genetic architectures of psychiatric disorders is an attainable goal with existing technologies (albeit both costly and cost-effective). Few predictions are perfectly safe, but we would argue that genetics is a particularly good bet for psychiatry.
