title: [Association of HLA-DQB1 alleles and the susceptibility to beta-thalassemia in Guangxi Chinese Zhuang nationality].
abstract: OBJECTIVE
  To investigate the relationship between HLA-DQB1 allele and susceptibility to beta-thalassemia in Guangxi Chinese Zhuang nationality.
  
  
  METHODS
  The polymorphism of the HLA-DQB1 loci in 64 randomly selected, unrelated Guangxi Zhuang individuals with beta-thalassemia was investigated by PCR-SSP.
  
  
  RESULTS
  Compared with normal controls, the frequency of HLA-DQB1*0604 allele was significantly increased in the patient group, with a relative risk(RR) of 9.9(chi 2 = 20.78, P < 0.005), while the frequencies of other HLA-DQB1 alleles did not in the patient group.
  
  
  CONCLUSIONS
  The susceptibility to beta-thalassemia in the Guangxi Zhuang individuals is associated with HLA-DQB1*0604 allele.
