title: Cytochrome P450 1A1 and manganese superoxide dismutase genes polymorphisms in ankylosing spondylitis.
abstract: OBJECTIVE
  To investigate the associations of cytochrome p450 1A1 (CYP1A1) and manganese superoxide dismutase (MnSOD) genes polymorphisms with the susceptibility to AS in Taiwan.
  
  
  METHODS
  The polymorphisms of CYP1A1 and MnSOD genes were determined in 70 patients with ankylosing spondylitis (AS) and 93 healthy controls by polymerase chain reaction (PCR)/restriction fragment length polymorphisms (RFLP) methods.
  
  
  RESULTS
  The genotype frequency of CYP1A1 4887C/A was significantly lower in patients with AS than in controls. The phenotype frequency of CYP1A1 4887A also tended to be decreased in patients with AS. There were no significant differences in the genotype, allele, and phenotype frequencies of MnSOD gene polymorphisms between patients with AS and controls.
  
  
  CONCLUSIONS
  CYP1A1 4887A may be a protective factor for the development of AS in Taiwan. However, MnSOD gene polymorphisms are not associated with the susceptibility to AS.
