High-Resolution HLA Typing of HLA-A, -B, -C, -DRB1, and -DQB1 in Kinh Vietnamese by Using Next-Generation Sequencing.


ABSTRACT: Human leukocyte antigen (HLA) genotyping displays the particular characteristics of HLA alleles and haplotype frequencies in each population. Although it is considered the current gold standard for HLA typing, high-resolution sequence-based HLA typing is currently unavailable in Kinh Vietnamese populations. In this study, high-resolution sequence-based HLA typing (3-field) was performed using an amplicon-based next-generation sequencing platform to identify the HLA-A, -B, -C, -DRB1, and -DQB1 alleles of 101 unrelated healthy Kinh Vietnamese individuals from southern Vietnam. A total of 28 HLA-A, 41 HLA-B, 21 HLA-C, 26 HLA-DRB1, and 25 HLA-DQB1 alleles were identified. The most frequently occurring HLA alleles were A?11:01:01, B?15:02:01, C?07:02:01, DRB1?12:02:01, and DQB1?03:01:01. Haplotype calculation showed that A?29:01:01?B?07:05:01, DRB1?12:02:01?DQB1?3:01:01, A?29:01:01?C?15:05:02?B?07:05:01, A?33:03:01?B?58:01:01?DRB1?03:01:01, and A?29:01:01?C?15:05:02?B?07:05:01?DRB1?10:01:01?DQB1?05:01:01 were the most common haplotypes in the southern Kinh Vietnamese population. Allele distribution and haplotype analyses demonstrated that the Vietnamese population shares HLA features with South-East Asians but retains unique characteristics. Data from this study will be potentially applicable in medicine and anthropology.
