title: [The heat shock protein 70-2 gene +1267(A/G) polymorphism and susceptibility to ankylosing spondylitis in Chinese Han population].
abstract: OBJECTIVE
  To investigate the association between the heat shock protein 70-2 gene polymorphism and ankylosing spondylitis (AS).
  
  
  METHODS
  The polymorphisms of HSP70-2 gene Pst I 1267 site were analysed in 176 Chinese Han AS patients and 127 healthy controls by PCR and restriction fragment length polymorphisms(RFLP) methods.
  
  
  RESULTS
  In AS patients HSP70-2 genotypes AA, AG and GG were 46.6%, 46.0% and 7.4% respectively, frequencies of A and G were 69.6%(A) and 30.4%(G). In healthy controls HSP70-2 genotypes AA, AG and GG were 44.1%, 48.8% and 6.9% respectively, frequencies of A and G were 68.5%(A)and 31.5%(G). No significant differences were found in the distribution of HSP70-2 genotypes and allele frequencies between AS patients and controls.
  
  
  CONCLUSIONS
  Our results indicate that the there may be no association of the HSP70-2 gene polymorphism with AS in Chinese Han population.
