Obsessive-compulsive disorder (OCD) is a psychiatric disorder characterized by obsessive thoughts, compulsive repetitive actions and, often, anxiety and depression. Its underlying causes and pathology remain largely unknown, although a genetic component has been suggested. Now, scientists have identified a gene whose absence causes OCD-like behavior in mice. The gene encodes Slitrk5, a neuron-specific transmembrane protein that is widely expressed throughout the central nervous system.
