5-HT2A receptor gene promoter polymorphism –1438A/G and bipolar disorder

Genetic factors, such as the genes involved in the serotonin pathway, probably play an important role in the pathogenesis of bipolar disorder, and serotonin type 2A (5-HT2A) receptor gene promoter polymorphism –1438A/G has been reported. This study investigated the association between –1438A/G polym
