Imaging genetics in obsessive-compulsive disorder: Linking genetic variations to alterations in neuroimaging

Abstract excerpt

Obsessive-compulsive disorder (OCD) occurs in ∼1-3% of the general population, and its often rather early onset causes major disabilities in the everyday lives of patients. Although the heritability of OCD is between 35 and 65%, many linkage, association, and genome-wide association studies have failed to identify single genes that exhibit high effect sizes.
