Distribution of HLA-C alleles in Shandong Han population of China / 中华微生物学和免疫学杂志

ABSTRACT

Objective To analyze the distribution of HLA-C alleles in Shandong Han population of China.Methods One hundred and fifty unrelated potential donors,self-claimed as Han population from Shandong province,were selected from China Marrow Donor Program.Genotypes of HLA-C with the donors were identified by PCR-SBT.The frequencies of allele were calculated with direct counting method and the differences with other populations were analyzed with SPSS16.0 x2 software.Results A total of 25 alleles of HLA-C were observed and the most common alleles were C * 0602 and C * 0702 with the frequency of more than 10.00％.Moreover,there were 16 kinds of alleles with the frequency of more than 1.00％ accounting for 95.33％ of the total alleles.The distribution of HLA-C alleles in Shandong Han population was similar to that in northern Han population,but had some differences with that in southern Han population.In addition,the distribution of HLA-C alleles in Shandong Han population significantly differed from that of German/African American.Conclusion This study on the distribution of HLA-C alleles in Shandong Han population provides valuable references for further studies on the genetics of HLA,cross-match for organ transplantation and other genetic-associated diseases in this population.
