Epidemiological studies have shown a lower prevalence of tardive dyskinesia (TD) among Chinese psychiatric patients compared to Caucasian and Black patient populations. It has been hypothesized that pharmacogenetic factors may underlie this cross-cultural difference. Due to the important implications of the dopamine D3 receptor gene (DRD3) in motor control, we investigated the frequency of polymorphic serine (ser) to glycine (gly) substitution of the gene DRD3 in Chinese schizophrenic patients. The sample size consisted of 65 patients with TD and 66 without TD. Patients were assessed for the severity of TD, the presence of akathisia and parkinsonian symptoms and were subsequently genotyped. We found no evidence that the dopamine D3 receptor gene is likely to confer susceptibility to the development of tardive dyskinesia in Chinese patients with schizophrenia.
