PG - 215-225 LID - S0198-8859(20)30341-4 [pii] LID - 10.1016/j.humimm.2020.06.006 [doi] AB - Studying the allele and haplotype distributions of human leukocyte antigen (HLA) loci at 2nd-field level in different populations was important. Allele and haplotype frequencies of HLA-A, -B, -C, -DRB1 and -DQB1 loci in 110 unrelated healthy Kazak individuals living in Xinjiang (China) were analyzed using polymerase chain reaction sequence based typing. Thirty HLA-A, 48 HLA-B, 24 HLA-C, 34 HLA-DRB1 and 18 HLA-DQB1 alleles were detected at the 2nd-field level in the Kazak population. Frequencies of HLA alleles, genotypes, and haplotypes were calculated, and some exhibited significantly different distributions among different populations. A neighbor-joining (NJ) tree, heatmap, multidimensional scaling (MDS) and principal component analysis (PCA) were used to explore the genetic relationships between the Kazak population and 32 reference populations distributed in Asia, Africa, America and Europe using frequency data of HLA-A, -B, -C and -DRB1 loci. The NJ tree, heatmap, and MDS of the 33 populations were constructed based on pairwise D(A) values of populations obtained by the HLA-A, -B, -C and -DRB1 allele frequencies. Different PCA plots were constructed based on the allele frequencies of HLA-A, -B, -C and -DRB1 or estimated haplotypic frequencies of HLA-A, -B, -C loci. The data obtained in the present research can be used for research on HLA-related diseases or paternity relationships, and aid to finding the best matched donors in stem cell transplantation for Kazak individuals.
