Several genetic components are supposed to contribute to its pathophysiology. In particular serotonergic and dopaminergic genes are the focus of investigation, endorsed by clinical efficacy of SSRI and atypical neuroleptics. In our studies serotonergic and dopaminergic genes were investigated for association with OCD in a case-control-study and in a family based sample. A multicenter study we are also part of the first genome-wide association study in OCD. In our own sample association between the serotonergic genes TPH2, 5HT2A as well as between DRD4 by early onset OCD was found by applying the Transmission Disequilibrium Test (TDT). In the investigated family based sample consisting of children with early-onset OCD several genes influencing monoaminergic neurotransmission were found to be associated with OCD. By this finding further evidence for the crucial role of serotonergic effectors for the pathophysiology of OCD is provided. Positive association was also detected between DRD4 and OCD, endorsing the discussion about the special role of the dopaminergic for early onset OCD. Further investigation on early onset OCD will further investigate for occurrence of copy number variations (CNVs) and their functional effects.
