title: [The mutation of deletion for glutathione S-transferase M1 gene in the tissue of hepatocellular carcinoma].
abstract: OBJECTIVE
  To Study whether the mutation of deletion for glutathione S-transferase M1 (GSTM1) gene occurred during the development of hepatocellular carcinoma (HCC).
  
  
  METHODS
  The genotypes of GSTM1 of 46 pairs of HCC tissue and the noncancerous liver tissue were detected by polymerase chain reaction (PCR).
  
  
  RESULTS
  The frequency of GSTM1 null genotype for HCC tissue was 78.26%, but 65.22% for the noncancerous liver tissue (P<0.05). The GSTM1 null genotypes of 6 HCC tissue were transformed from the non- null genotypes of the noncancerous liver tissue. According to Hardy-Weinberg law., the rate of deletion mutation for GSTM1 gene was inferred to be 38.89%.
  
  
  CONCLUSIONS
  The results suggested that the mutation of deletion for GSTM1 gene had occurred during the development of HCC.
