Further evidence supporting the association between 5HTR2C gene and bipolar disorder

Abstract

Three 5HTR2C polymorphisms were investigated in bipolar (BD) spectrum disorders. The functional rs6318 G (Cys) allele was more frequent in BD patients than in controls (P=0.0036). Thus, 5HTR2C may have a role in BD. Further investigation is required to understand its involvement in co-morbidity for substance use disorders (SUDs). © 2009 Elsevier Ltd.
