title: [The analysis of HLA-B15 and B40 antigen polymorphism in Xi'an].
abstract: OBJECTIVE
  To study the distribution character of HLA-B15 and B40 in Xi'an population.
  
  
  METHODS
  PCR-SSP and reverse PCR-SSOP reaction pattern were used to type the HLA-B15 and B40 alleles of 3 601 blood samples in Xi an.
  
  
  RESULTS
  HLA-B15 and B40 gene frequencies were 0.1483 and 0.1414, respectively, among 3 601 blood samples from Xi'an population which take up 57.91% in HLA-B alleles.
  
  
  CONCLUSIONS
  The distribution character of HLA-B15 and B40 alleles in Xi'an population were different compared with other populations.
