title: [Susceptibility to endometriosis in women of Han Nationality in Guangdong Province associated with Msp I polymorphisms of cytochrome P450 1A1 gene].
abstract: OBJECTIVE
  To assess the possible association of the Msp I polymorphisms of cytochrome P4501A1(CYP1A1) gene with the susceptibility to endometriosis in women of Han Nationality in Guangdong Province.
  
  
  METHODS
  Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was employed to analyze the 3 genotypes m1m1, m1m2 and m2m2 in 3'-flanking region of CYP1A1 in 76 patients with endometriosis and 80 healthy controls.
  
  
  RESULTS
  The frequencies of genotypes m1m1, m1m2 and m2m2 were 30.3 %, 50.0 % and 19.7 % in patients with endometriosis while 42.5 %, 45.0 % and 12.5 % in the controls, respectively, showing no statistically significant difference in the frequencies of the three genotypes between the 2 groups. The frequencies of two alleles were of no significant difference between the patients and controls, either.
  
  
  CONCLUSIONS
  Msp I polymorphisms of cytochrome P4501A1 in itself might not be associated with the susceptibility to endometriosis in women of Han Nationality in Guangdong Province.
