title: [Study on the genetic polymorphisms of human glutathione-S-transferase A1 in Hakka population in South China].
abstract: OBJECTIVE
  Glutathione-S-transferase A1 (GSTA1) is one of the major phase II detoxification enzymes in the cytosol, which genetic polymorphisms distribution is different in different ethnic, national and regional population. Up to now, GSTA1 genetic polymorphisms has been rarely reported in China. The purpose of the study was to investigate the distribution of genetic polymorphisms of human GSTA1 in Hakka population in South China.
  
  
  METHODS
  Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to identify the genotypes of GSTA1 gene and the data were analyzed with SPSS10.0 software.
  
  
  RESULTS
  The GSTA1 genetic polymorphisms were detected in 480 samples. The frequency of GSTA1 * A/ * A,GSTA1 * A/ * B and GSTA1 * B/ * B were 77.1%, 21.7% and 1.2% respectively. And the GSTA1 genetic polymorphism distribution was in accordance with the Hardy-Weinberg equilibrium rule. There were no difference in the GSTA1 genetic polymorphisms among the different groups of age or gender. Logistic regression analysis showed that there were no association between the GSTA1 genetic polymorphism and family history of hypertension, coronary heart disease, stroke, lung cancer and nasopharyngeal cancer, et al.
  
  
  CONCLUSIONS
  The GSTA1 gene existed polymorphism among Hakka in South China.
