The MTHFR gene predict weight change in drug-naive patients with bipolar II disorder

Abstract

Objective: Patients with BP-II have a higher prevalence rate of metabolic disturbance and obesity than do the general population. Genetic variants of the methylene tetrahydrofolate reductase (MTHFR) gene have been regarded as predictors of weight gain in schizophrenia. In the present study, we investigated whether the MTHFR C677T polymorphism may predict changes in metabolic indices after 12 weeks of treatment in patients with BP-II.
