Researchers have found new molecular evidence that 11 genetic regions have strong links to schizophrenia and bipolar disorder, including six regions not previously observed. The researchers also found that many of these DNA variations contribute to both diseases. The findings, reported by the Psychiatric Genome-Wide Association Study Consortium (PGC), represent significant advances in these severe and debilitating disorders. Scientists believe they can start to link the genetic variations to the breakdown of specific brain functions which causes both diseases.
