ABSTRACT
<p><b>OBJECTIVE</b>To investigate the genetic polymorphism of HLA-DRB1 locus in Jiangsu-Zhejiang-Shanghai Han population and analyze the characteristic of the allele frequency distribution in comparison with that of other populations.</p><p><b>METHODS</b>The technique of polymerase chain reaction-sequence specific primers (PCR-SSP) and reverse polymerase chain reaction-sequence specific oligonucleotide probe (PCR-SSOP) was adopted in genotyping a sample of 626 unrelated healthy individuals collected from a Chinese Han population in Jiangsu-Zhejiang-Shanghai area. HLA-DRB1*0101-1001, DRB3, DRB4 and DRB5 were detected. The allele frequency of HLA-DRB1 was calculated, and the allele frequency distribution of HLA-DRB1 in this population was compared with the results from other populations.</p><p><b>RESULTS</b>HLA-DRB1*0101, 0301, 0701, 09012, 1001, 1201, 1202, 1301/02, 1303/04, 1401/04/05, 1402/03/1305, 1501/02, 16021 and 04xx, 08xx were detected in Jiangsu-Zhejiang-Shanghai Han population. The common HLA-DRB1*allele included 09012(17.97%), 04xx(12.53%), 1202(11.42%) and 1501/02(11.02%). The polymorphism information content is 0.9024, and expected heterozygosity is 0.9634 in Jiangsu-Zhejiang-Shanghai Han population.</p><p><b>CONCLUSION</b>The HLA-DRB1 distribution of Jiangsu-Zhejiang-Shanghai Han population shares some genetic characteristic with other Han populations, but it exhibits its own characteristic, suggesting the intermediate state of this population between the southern and northern Han populations. The polymorphism of HLA-DRB1 of Jiangsu-Zhejiang-Shanghai Han population is the most abundant one in this study.</p>
