title: A comparison of glutathione S-transferase mutant frequencies in healthy Han and Uygur Chinese.
abstract: OBJECTIVE
  This study was to compare the frequencies of genetic polymorphisms of GSTM1, GSTT1, and GSTP1 in Uygur Chinese with those in Han Chinese.
  
  
  METHODS
  GSTM1 and GSTT1 polymorphisms were analyzed by a PCR-Multiplex procedure, whereas GSTP1 polymorphism was analyzed by PCR-RFLP.
  
  
  RESULTS
  The frequency of GSTM1 null genotype in Han Chinese (56.1%) was similar to that in Uygur Chinese (53.2%) (P = 0.592), whilst the frequency of GSTT1 null genotype in Han Chinese (50.0%) was significantly (P < 0.05) higher than that of Uygur Chinese (26.6%). GSTP1 had a genotype distribution of 60.7% I/I, 35.2% I/V and 4.1% V/V in Han Chinese, and 51.3% I/I, 40.2% I/V and 8.4% V/V in Uygur Chinese.
  
  
  CONCLUSIONS
  There is marked ethnic difference in the mutant frequencies of GSTT1 and GSTP1, but not GSTM1, between Uygur and Han Chinese.
