ABSTRACT
<p><b>OBJECTIVE</b>To investigate whether the -1438G/A polymorphism in the promoter region of 5-HTR2A gene associates with the weight gain following antipsychotic agents (APS) acute treatment in schizophrenic patients.</p><p><b>METHODS</b>Eighty-four Chinese Han patients with schizophrenia at the first onset were recruited from among 70 nuclear families. The polymorphism of 5-HTR2A gene was determined with PCR-RFLP technique. Body weight was measured in the patients on admission after 10 weeks of treatment with risperidone or chlorpromazine.</p><p><b>RESULTS</b>There were no statistically significant differences in the distribution frequencies of genotype (chi2: 0.172, v1, P > 0.05) and allele (chi2: 0.121, v1, P > 0.05) of -1438G/A polymorphism of 5-HTR2A gene between subgroups (weight gain >or= 7% or < 7%). Likewise, there was no significant difference in weight gain between genotype groups. By means of transmission disequilibrium test and quantitative transmission disequilibrium test, no significant association between the -1438G/A polymorphism of 5-HTR2A gene and weight gain was observed.</p><p><b>CONCLUSION</b>5-HTR2A gene -1438G/A polymorphism was probably not associated with APS-induced weight gain in Chinese Han patients with schizophrenia in this study.</p>
