We as the PGC TS/OCD Working Group in recent years have identified the need to get organized in subgroups that tackle individual research aims in domains relevant to the overall mission. For example studying the genetic (risk) architecture of symptom dimensions (e.g. obsessive-compulsive symptom dimensions) in population-based samples might help to shed light on the genetic risk to develop either TS and/or OCD. We therefore have established subgroups that have their own chairs and organize their research under the umbrella of the PGC TS/OCD Working Group. This website will give you an insight into the individual subgroups and their work once the website is completed. If you have questions now please don't hesitate to contact our co-chairs Dr. Manuel Mattheisen and Dr. Jeremiah Scharf.
