    Abstract:
    OBJECTIVE: To investigate the polymorphisms of HLA-DPA1 and HLA-DPB1 loci of Han population in Zhejiang province of China. METHODS: The alleles of HLA-DPA1 and HLA-DPB1 loci in 100 unrelated healthy individuals were analyzed using polymerase chain reaction-sequence based typing. RESULTS: Eight HLA-DPA1 alleles and 19 HLA-DPB1 alleles were found in the population. The HLA-DPA1 alleles with higher frequencies were DPA1*020202 (47.0%), DPA1*010301 (38.5%) and DPA1*020101(10.5%). The HLA-DPB1 alleles with higher frequencies were DPB1*0501, DPB1*020102 and DPB1*040101. The frequencies were 39.5%, 13.5% and 13.0%, respectively. A total of 44 estimated DPA1-DPB1 haplotypes were detected. The HLA-DPA1*020202-DPB1*0501(29.5%) was the most frequent haplotype. CONCLUSION: The polymorphism data of the HLA-DPA1 and -DPB1 were obtained in Han population in Zhejiang province of China. There was linkage disequilibrium between the two loci.
