Frequencies of HLA-A, B and DRB1 allele and haplotype were calculated by Arlequin software.ResultsThe total numbers of HLA-A, B and DRB1 alleles are 18, 43, 13 respectively. The obviously high frequency alleles are A*11, A*02, A*24, A*33, B*40, B*15, B*46, B*13, DRB1*12, DRB1*15, DRB1*09 and DRB1*04, with accumulative frequency of each locus being more than 50%. The most common haplotypes are A2-B46, B46-DR9, A11-DR12 and A2-B46-DR9.ConclusionThe distribution of HLA-A, B and DRB1 allele and haplotype of cord blood in Guangzhou Cord Blood Bank has typical characteristics of southern Chinese Han population. Authors' data may help in searching for appropriate donors."xsd:string |
