ABSTRACT
<p><b>OBJECTIVE</b>To analyze the distribution of the human leukocyte antigen (HLA)-A, B and DRB1 allele and haplotype in cord blood samples preserved in Guangzhou Cord Blood Bank collected in the last 10 years.</p><p><b>METHODS</b>The HLA-A, B and DRB1 genotyping of 4194 cord blood samples were detected by Special Monoclonal Tray, PCR-sequence specific promer (PCR-SSP), PCR-sequence specific oligonucleotide probe (PCR-SSO) and sequence based typing (SBT). Frequencies of HLA-A, B and DRB1 allele and haplotype were calculated by Arlequin software.</p><p><b>RESULTS</b>The 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.</p><p><b>CONCLUSION</b>The 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.</p>
