title: [Comparison of genetic polymorphism of cytochrome CYP2C19 between men and women in Chinese population].
abstract: OBJECTIVE
  To assess the effect of gender on genetic polymorphism of cytochrome CYP2C19 in Chinese population.
  
  
  METHODS
  The genetic polymorphism of 140 healthy Chinese were analysed by PCR-RFLP (restriction fragment length polymorphism).
  
  
  RESULTS
  Of 52 genotyped male subjects, 23 (44.23%) were homozygous for wildtype (wt/wt), 6 (11.54%) were homozygous for CYP2C19 m1 (m1/m1), and 23 (44.23%) were heterozygous for CYP2C19 m1 or CYP2C19 m2 (wt/m1 or wt/m2); and among the 88 genotyped female subjects, 31 (35.23%) were homozygous for wildtype (wt/wt), 13 (14.82%) were homozygous for CYP2C19 m1 (m1/m1), and 44 (50.0%) were heterozygous for CYP2C19 m1 or CYP2C19 m2 (wt/m1 or wt/m2); no homozygous genotype for CYP2C19 m2 (m2/m2) was found in the study.
  
  
  CONCLUSIONS
  There is no statistical difference in ocurance of wt/wt and m1/m1 between in male and in female, so gender have no significant effect on genetic polymorphism of cytochrome CYP2C19.
