title: Association study between glutathione S-transferase P1 polymorphism and schizophrenia in the Korean population.
abstract: This study is aimed to test the association between the coding sequence functional polymorphism (Ile105Val) of glutathione S-transferase P gene (GSTP1) and schizophrenia in the Korean population. Two hundred fourteen patients with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria and 110 healthy controls were enrolled in this study. Patients and controls were biologically unrelated age and sex-matched native Koreans. Genotyping for GSTP1 polymorphism was performed by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). Genotype and allele distributions of GSTP1 polymorphism in patients with schizophrenia were not significantly different from those of the controls. Comparisons of clinical variables including Positive and Negative Syndrome Scale (PANSS), change of Brief Psychiatric Rating Scale (BPRS), number of admission, and onset age also were not different according to genotype distribution. The present study suggests that GSTP1 polymorphism may not confer susceptibility to development of schizophrenia in the Korean population.
