The occurrence of mania during antidepressant treatment is a key issue in the clinical management of bipolar disorder (BP). The serotonin transporter (5-HTT) is the selective site of action of most proserotonergic compounds used to treat bipolar depression. The 5-HTT gene (SLC6A4) has 2 known polymorphisms. The aim of this study was to investigate the role of the SLC6A4 variants in the pathogenesis of antidepressant-induced mania in BP.
