title: [The analysis of HLA-A, B and DRB1 allelic polymorphism in Han race population in Lanzhou region of China].
abstract: OBJECTIVE
  To investigate the HLA-A, B and DRB1 allele polymorphism of the Han race population in Lanzhou area.
  
  
  METHODS
  Polymerase chain reaction-sequence specific primer was used to detect HLA-A, B and DRB1 alleles in 200 unrelated healthy Han individuals from Lanzhou region, Northwest China, and the results were compared with those of Han populations in North, South and Northwest China, and Hui, Uigur and Tibetan population in China.
  
  
  RESULTS
  Fourteen of alleles were detected and identified for HLA-A; 32 for HLA-B; and 13 for HLA-DRB1. HLA- A*01, A*02,A*11,A*24, A*30, A*31, A*33; HLA- B*13, B*15, B*40, B*44, B*46, B*51, B*58, B*60; HLA- DRB1*04,. DRB1*07, DRB1*08, DRB1*09, DRB1*11, DRB1*12, DRB1*14 and DRB1*15 were the most common alleles. The frequencies of HLA-A, B and DRB1 genes of Lanzhou Han race were close to that of North China Hans and Hui population in Northwest China, and a little different to that of South China Hans. The HLA-DRB1 alleles were significantly different to those of Uigur and Tibetan race population of China.
  
  
  CONCLUSIONS
  The allelic polymorphism of HLA-A,B and DRB1 loci of Han race population in Lanzhou area was between North and South Han race of China, close to Northwest China Hui, and markedly different to Northwest China Uigur and Tibetan race populations.
