The OCD workgroup has been a part of the PGC since 2013. Our group aims to understand the underlying causes of OCD as well as its biological relationship with other disorders through large scale genome-wide studies. In 2018 we have published the largest OCD GWAS to date, a collaboration between the IOCDF-GC and the OCGAS. We are about to publish the next iteration of our OCD GWAS with a total of about 14,000 cases.

Our interdisciplinary membership includes graduate and postdoctoral trainees as well as distinguished faculty in psychiatry, child psychiatry, neurology, psychology, biostatistics, genetics, and genetic epidemiology. Data currently included in the working group efforts are based on the work of several consortia and teams across the globe.
