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-DRBI. The most frequent alleles were HLA-A * 2402(0. 2097), HLA-B * 1302(0.0699), and HLA-DRBI * 0701 (0. 1237). The most common HLA-A-B-DRBI 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. 相似文献

Objective To study genetic polymorphism of 6 Y chromosomal STR in Hui ethnic group living in Ningxia Hui ethnic autonomous region, in order to evaluate their usefulness in forensic science and enrich the Chinese genetic information resources. Methods We investigated 101 unrelated, healthy, male individuals of Hui ethnic group and studied their allelic frequency distribution and haplotype diversity of 6 Y chromosomal STR. Primer for each loci was labeled with the fluorescent by FAM (blue) or TAMRA(yellow). The data of Hui ethnic group were generated coamplification, GeneScan, genotype, and genetic distribution analysis. Results 31 alleles and 43 phenotype(DYS385) were detected, with the frequencies ranging from 0. 0099- 0. 7129. Out of a total of 101 individuals, 96 showed different haplotypes; 91 were unique; 5 were found 2 times. The haplotype diversity for 6 Y-STR loci was 0. 9990. Conclusion The date obtained can be valuable for individual identification, paternity testing in forensic fields and for population genetics because of 6 Y-STR loci high polymorphism. 相似文献
