As part of a multinational, collaborative effort, researchers from the Broad Institute, Massachusetts General Hospital (MGH), and scores of other institutions from all over the world have helped identify over 100 locations in the human genome associated with the risk of developing schizophrenia in what is the largest genomic study published on any psychiatric disorder to date. The findings, which are published online in Nature, point to biological mechanisms and pathways that may underlie schizophrenia, and could lead to new approaches to treating the disorder, which has seen little innovation in drug development in more than 60 years.

Autism spectrum disorder and intellectual disability often occur together and may even share similar genetic causes. Researchers reporting in the Cell Press journal Cell Reports have now linked mutations in a particular gene to the two disorders in humans. By revealing these genetic changes and their potential impact on common brain processes, researchers may uncover treatment approaches that could benefit a variety of patients.
