Abstract
Objective: Tardive dyskinesia (TD) is a long-term adverse effect of antipsychotic. We evaluated candidate functional polymorphism of the G protein β3 subunit (GNB3) gene for association with drug-induced TD in the Korean schizophrenic patients. Methods: We investigated whether the C825T polymorphism of the GNB3 gene is associated with the TD in a Korean sample of schizophrenic patients with (n = 83) and without TD (n = 126), matched for antipsychotic drug exposure and other relevant variables. Results: The distribution of genotypes and allele frequencies of GNB3 were not different between schizophrenic patients with TD and without TD (p > 0.05). Conclusion: Within the limitations imposed by the size of the clinical sample, these findings suggest that the GNB3 825 C/T single nucleotide polymorphism (SNP) does not contribute significantly to risk for TD.
