Genetics of Obsessive-Compulsive Disorder
An observational study of Obsessive Compulsive Disorder, run by National Institute of Mental Health (NIMH) at 1 site in United States.
Trial summary
The purpose of this study is to identify genes that affect susceptibility to obsessive-compulsive disorder (OCD). By identifying genes that increase or decrease the risk of OCD, researchers can better understand how the condition develops and ultimately improve treatment for people with OCD.

About this study
Official title: Genetics of Obsessive-Compulsive Disorder: A Collaborative Study
The purpose of this study is to identify genes that affect susceptibility to obsessive-compulsive disorder (OCD). By identifying genes that increase or decrease the risk of OCD, researchers can better understand how the condition develops and ultimately improve treatment for people with OCD.
OCD is a severe, familial condition that affects approximately 2% of the population. The way OCD is inherited is not clearly understood, but researchers believe it is complex and involves multiple genes. This study will detect and localize genes that increase or decrease susceptibility to OCD. The data collected from this study will be combined with data from other research studies to determine gene linkage and association.
Read the detailed description
Obsessive-compulsive disorder (OCD) is a severe, heritable condition with a lifetime prevalence of about two percent of the population. The mode of inheritance is poorly understood but is likely complex, involving multiple loci of small to major effect. Since 1995, the NIMH-IRP has been active in a multi-center family study of OCD, led by Dr. Gerald Nestadt of Johns Hopkins University, which was approved via a competitive NIMH extramural application (MH 502140). An expanded consortium of sites (including new sites at Brown and Harvard Universities) anticipates adding 300 new affected sib-pair families over the next three years. This sample will be used for linkage and association analyses. Data will be shared within this consortium of investigators studying OCD, and will eventually be combined with data obtained from a second consortium.
