ANALYZING HLA HAPLOTYPE OF THE LOCI HLA-A, -B, AND -DRB1 IN MONGOLIA ETHNIC GROUP / 药物分析学报

ABSTRACT

Objective To investigate HLA-A,-B and -DRB1 allele and HLA-A-B-DRB1 haplotype frequencies in Mongolia ethnic group. Methods HLA-A, -B, -DRB1 allele and haplotype in the Mongolia ethnic group were investigated based on 93 individuals by PCR- sequence-based typing (SBT) method. Results Twenty-one alleles were detected for HLA-A, 44 for HLA-B, and 26 for HLA-DRB1. The most frequent alleles were HLA-A*2402(0.2097), HLA-B*1302(0.0699), and HLA-DRB1*0701(0.1237). The most common HLA-A-B-DRB1 haplotype were A*3001-B*1302-DRB1*0701, A*0101-B*3701-DRB1*1001, followed by the A*0201-B*4601-DRB1*0901, A*2402-B*4801-DRB1*1101, A*2402-B*5201-DRB1*1501, A*3201-B*3503-DRB1*1301, and A*3303-B*5801-DRB1*0301, which were also presented in Chinese populations. Conclusion The data can be used in forensic and paternity tests to estimate the frequency of a DNA profile or anthropologic research. The characteristics of the distribution of HLA alleles revealed that Mongolia ethnic group is characterized by northern Mongolian Chinese.
