Abstract:
Objective To investigate the allelic polymorphism of Human Leukocyte Antigen(HLA)-DRB1*04 in Southern and Northern Chinese Han populations.Method A total of 104 and 168 samples of HLA-DRB1*04 alleles from Southern and Northern Chinese Han populations respectively were genotyped at high-resolution by PCR-SBT,and then the DRB1*0406/0449 ambiguous allele pairs were identified via high-resolution PCR-SSP.The allelic distribution of DRB1*04 in Southern and Northern Chinese Han populations were compared with other different populations by chi-square test.Results All 56 ambiguous allelic pairs of DRB1*0406/0449 were identified as DRB1*0406.A total of 5 alleles were observed in Southern Chinese Han population and the most frequent alleles were DRB1*0405(47.32%),DRB1*0406(24.24%)and DRB1*0403(16.35%).There were 10 alleles tested in Northern Chinese Han population,and the major alleles were DRB1*0405(40.48%),DRB1*0406(18.45%) and DRB1*0403(17.26%).The overall distribution of DRB1*04 alleles in Southern and Northern Chinese Han differed significantly from that of the Caucasian,African American,Hispanics,and Asian and Pacific Islanders,but not from the Korean.Conclusions The overall distribution of HLA-DRB1*04 alleles differed significantly between Southern and Northern Chinese Han populations,but the major alleles DRB1*0405,DRB1*0406 and DRB1*0403 showed the same distribute characteristic.The distribution of DRB1*04 alleles in different populations has their own characteristics.
