摘要：
Objective: To investigate the association between a Ser9Gly polymorphism of die dopamine D3 receptor gene (DRD3) and schizophrenia. Methods: 408 schizophrenic patients and 172 control subjects were compared with regard to their DRD3 Ser9Gly genotypic and allelic frequencies. In addition, we carried out a family-based association study including 183 pedigrees (472 subjects) using the transmission disequilibrium test (TDT). Results: No significant differences of genotype or homozygosity distribution were identified between patients and controls. When patients were stratified according to gender, response to treatment, age at onset, no significant differences were observed. Neither allele A (Set), or G (Gly) were preferentially transmitted from parents to affected offspring. Conclusion: The hypothesis that the DRD3 Ser9Gly polymorphism plays a predisposing role in schizophrenia is not supported by this study. (C) 2007 Elsevier B.V. All rights reserved.
