    ABSTRACT: This study is to investigate HLA haplotypes in Jiangsu-Zhejiang-Shanghai Han population based on 166 families by serological and molecular biological HLA typing methods and to analyze the distribution characteristic of HLA haplotypes. The results showed that allele frequencies of more than 10% for HLA antigens were A2, A11, A24, B13, B46, B60, DRB1 *04, DRB1 *08, DRB1* 09, DRB1 * 12 and DRB1 * 15. In the analysis of HLA haplotypes, 128 kinds of A-B haplotypes and 182 kinds of B-DRB1 haplotypes were found, comprising 19.28% (128/664) and 27.41%(182/664) of total theoretical haplotypes, respectively. 18 kinds of A-B haplotypes and 23 kinds of B-DRB1 haplotypes occurred at frequencies of more than 0.5% (linkage disequilibrium value, delta > 0) .351 kinds of A-B-DRB1 haplotypes were found, comprising 52.86% (351/664) of total theoretical haplotypes, and 8 kinds of A-B-DRB1 haplotypes occurred at frequencies of more than 0.5% (delta > 0). The common A-B-DRB1 haplotypes were A30-B13-DRB1 * 07(4.22%), A2-B46-DRB1 * 09(3.77%), A33-B58-DRB1 * 17(3.01%), A33-B58-DRB1 * 13.1 (1.81%) and A11-B75-DRB1 * 12(1.51%). The HLA haplotype distribution of Jiangsu-Zhejiang-Shanghai Han population has its own genetic characteristics, so it suggests this population is between southern and northern Han population. The HLA polymorphism of Chinese Han population is more abundant in East Asian populations.

    ABSTRACT: A rapid and accurate method of DNA typing for HLA was established to compensate the unsatisfactory serological typing for HLA before transplantation. DNA typing for HLA using by reverse polymerase chain reaction with sequence-spcific oligo probe (reverse PCR-SSOP) could detect HLA-A(*0101 - 8001) and B(*07021 - 8201). The results showed that HLA-AB alleles were successfully analysed in 60 matching subjects and 16 control DNAs from UCLA by reverse PCR-SSOP without false negtive and false positive results. The results were concordance with those of UCLA. The error rate of serological typing was 6.4% for HLA-A and 7.4% for HLA-B. The serological typing missed HLA-A24 and HLA-B46 for two patients with leukemia respectively. Our results suggest that DNA typing for HLA by reverse PCR-SSOP has proved to be a high-resolution, high-specificity, rapid and accurate technique, suitable for clinical application with a greater precision than serological typing.
