To determine whether genetic polymorphisms related to pharmacodynamics with metabolic adverse effects, namely leptin promoter (<i>LEP</i>) rs7799039, leptin receptor rs1137101, dopamine D2 rs4436578, serotonin 5-HT2A rs6313, and serotonin 5-HT2C rs518147 and rs12836771, are associated with hyperglycemia induced by risperidone or clozapine in adult Thai patients with psychosis.
The comparison of these markers in antipsychotic-naïve FEP patients (N = 38) and CS (N = 37) revealed significantly higher levels of ferritin (P = .004), and resistin (P = .03) and lower level of leptin (P = .03) among FEP patients group.
The present study detected increased leptin levels in the early stages of psychosis and significant correlations between leptin levels and anthropometric, lipid, hormone, and cytokine parameters.
Polymorphisms of the 5-HT2C receptor and leptin genes are associated with antipsychotic drug-induced weight gain in Caucasian subjects with a first-episode psychosis.
