title: TGF-beta1-800G>A polymorphism and cerebral infarction in Chinese Han population.
abstract: OBJECTIVE
  To investigate the association between transforming growth factor beta1(TGF-beta1)-800G>A polymorphism and cerebral infarction (CI).
  
  
  METHODS
  The genotypes of 247 patients with atherosclerotic cerebral infarction and 167 sex- and age-matched healthy controls were detected by PCR-RFLP, and the frequency distribution of alleles calculated.
  
  
  RESULTS
  TGF-beta1-800G>A polymorphism was found in Han population in Hunan Province, China. The distribution of -800G>A genotypes was consistent with Hardy-Weinberg balance in the CI and healthy control group. There was no significant difference between genotypes and allele frequency of TGF-beta1-800G>A in the CI and control group (P>0.05). Logistic regression analysis suggested that no genotypes could increase or reduce the risk of CI onset (P>0.05).
  
  
  CONCLUSIONS
  TGF-beta1-800G>A polymorphism is not associated with CI in Han population in Hunan Province.
