“Copy number variation in obsessive-compulsive disorder and tourette syndrome: a cross-disorder study” ( J Am Acad Child Adolesc Psychiatry 2014)
Obsessive-compulsive disorder (OCD) and Tourette syndrome (TS) are heritable neurodevelopmental disorders with a partially shared genetic etiology. This study represents the first genome-wide investigation of large (>500 kb), rare (<1%) copy number variants (CNVs) in OCD and the largest genome-wide CNV analysis in TS to date.
