The results of their study were published this month in the journal Human Molecular Genetics . Wired News delivered to your inbox or hand-held device. The researchers found that most of the family members shared two damaged genes located on the first chromosome of a human being's 23 pairs. While this latest discovery is considered promising, the research on the genetics of schizophrenia is far from over, and the hunt for other culpable genes is still on.
