“…In contrast to ISEA, countries in MSEA are geographically closer but populated by ethnic groups that speak different language families, suggesting different genetic roots. Most Vietnamese people belong to the Kinh ethnic group and speak the Vietic branch of Austroasiatic language 40 , while Cambodians speak the Khmer branch. The Thai language belongs to the Tai-Kadai family while Burmese belongs to the Tibeto-Burman family.…”

Tuberculosis presents a global health challenge. Mycobacterium tuberculosis is divided into several lineages, each with a different geographical distribution. M. tuberculosis lineage 1 (L1) is common in the high-burden areas in East Africa and Southeast Asia. Although the founder effect contributes significantly to the phylogeographic profile, co-evolution between the host and M. tuberculosis may also play a role. Here, we reported the genomic analysis of 480 L1 isolates from patients in northern Thailand. The studied bacterial population was genetically diverse, allowing the identification of a total of 18 sublineages distributed into three major clades. The majority of isolates belonged to L1.1 followed by L1.2.1 and L1.2.2. Comparison of the single nucleotide variant (SNV) phylogenetic tree and the clades defined by spoligotyping revealed some monophyletic clades representing EAI2_MNL, EAI2_NTM and EAI6_BGD1 spoligotypes. Our work demonstrates that ambiguity in spoligotype assignment could be partially resolved if the entire DR region is investigated. Using the information to map L1 diversity across Southeast Asia highlighted differences in the dominant strain-types in each individual country, despite extensive interactions between populations over time. This finding supported the hypothesis that there is co-evolution between the bacteria and the host, and have implications for tuberculosis disease control.

“…To determine the genetic flow among populations, pairwise genetic distance (R st ) for each locus were estimated between previously reported populations using YHRD calculation online. The observed haplotype frequency in this study was compared with databases in YHRD consisting of population from central Thailand 12 , Hongkong 13 , Japan [14][15][16] , Laos and Nepal 17,18 , South Korea [19][20][21] , Taiwan 22 , and Vietnam 7,23 . Haplotypes of the northern Thai population were significantly different from those of the other 8 populations (P < 0.05).…”

“…Previous studies demonstrated the diversity of Y-STRs on different populations between Africa, Asia, Europe, Latin America, and North America including the different ethnic groups 7,8 . Since Thailand is located on Mainland Southeast Asia which was a route for people migration from southern China and other nationalities during historical migration and settlement, it promoted ethnic diversity.…”

Background:The investigation of Y-short tandem repeats (Y-STRs) has been widely performed in forensic caseworks. Due to variation between populations, understanding of genetic information within individual a population could provide the database and scientifically reliable results. This study was to investigate allele and haplotype frequencies of Y-STRs among localized people who lived in northern Thailand.Methods: A retrospective descriptive study was conducted by gathering medical reports of Y-STRs typing. The allele frequency and gene diversity as well as haplotype frequency and diversity were calculated. Pairwise genetic distance (R st ) was also calculated based on haplotype pattern by using AMOVA and Multidimensional Scaling (MDS) tools. Results:The result showed that DYS389II, DYS439, and DYS392 represented the highest number of allele patterns. The highest and lowest allele frequency was found to be allele 14 of DYS437 and allele 13 of DYS437, respectively. The highest and lowest gene diversity was observed in DYS389II and DYS437, respectively. One-hundred and sixty different haplotypes were defined where 144 carried a unique haplotype and 16 carried a replicate haplotype. A significant R st value was obtained between the studied population and central Thai population. Conclusion:This study provided genetic database of Y-STRs among localized population in northern region of Thailand. The genetic structure of our subjects also represented the significant close relationship with some other populations in Southeast Asia.

“…Intriguingly, there is no Vietnamese historical record of how and when they diverged into different groups geographically and linguistically. Despite substantial efforts to study the many ethnolinguistic groups in Vietnam from the perspective of genetics (Duong et al, 2018;Liu et al, 2020;Macholdt et al, 2020;Miranda-Barros et al, 2016), the limited data on minority people has been an obstacle to constructing the history of the Vietnamese Bouyei peoples. Meanwhile, the Bo Y along with the Tu Di communities is threatened with poverty and loss of many cultural heritages.…”

Objectives: Genetic characteristics were investigated based on short tandem repeat (STR) data to assess the relationship between two Vietnamese Bouyei populations in Vietnam. Methods: We collected hair and buccal swab samples from two separate Bouyei populations in the mountainous region of Northern Vietnam, which are the Bo Y in Ha Giang Province and the Tu Di in Lao Cai Province. The study included data of 23 autosomal and 27 Y-chromosome STRs loci of 96 unrelated participants from a total Vietnamese Bouyei population of under 3300 individuals. Results:The results showed that these STR markers are valuable for differentiation of individuals and human genetic studies in Vietnamese Bouyei populations. Genetic analysis indicated that Tu Di and Bo Y people were from the same Bouyei population in China. Conclusions:The results supported the official historical records of the region and the classification of the Vietnamese government. Furthermore, the genetic data provided in this study will be helpful in investigating the genetic genealogy evolution and settlement or migration patterns of the Bouyei populations in Vietnam.
