OCD has a heritability of approximately 40–65%. First-degree relatives of individuals with OCD have a 4–8 times higher risk.
How Genetic Is Obsessive-Compulsive Disorder?
Genetics plays a meaningful role in Obsessive-Compulsive Disorder, with heritability estimated at around 40%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Obsessive-Compulsive Disorder: SLC1A1,SAPAP3,GRIK2. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
