[Frequencies of high-resolution HLA-Cw* alleles in China Northern Han population].
This study was purposed to investigate the frequencies of HLA-Cw* loci in China Northern Han population at gene level and to analyze the population genetic characteristics of HLA-Cw* alleles and distribution difference of gene frequency in regions. The high resolution genotyping for HLA-Cw* loci of 420 cases in China Northern Han population was performed by using PCR-SSP typing technique and their distribution regularity was analyzed statistically. The results showed that 30 HLA-Cw* alleles were detected, among which the frequency of Cw* 0102 (0.1776), 0702 (0.1217), 0602 (0.1150) were highest; other alleles with higher frequency were as follow in proper order: Cw* 0304, 0801, 0303, 0302, 0401, 1402. The rare observed HLA-Cw* 0506, 0810, 1510, 1601 and 1701 were detected firstly in this population. The statistical analysis indicated that the genotype distribution of HLA-Cw* loci coincides with the Hardy-Weinberg test. In conclusion, application of high resolution allele typing can accurately understand the distribution regularity and characteristics of HLA-Cw* alleles in China Northern Han population which provides the basis for research related with HLA-Cw* loci.
