The Kra–Dai linguistic family includes Thai and Lao as well as a great number of languages spoken by ethnic minorities in Southeast Asia. In Thailand, a dozen of other Kra–Dai languages are spoken in addition to Thai, the national language. The genetic structure of the Kra–Dai-speaking populations in Thailand has been studied extensively using uniparentally inherited markers. To extend this line of genetic investigation, this study used 15 autosomal microsatellites of 500 individuals from 11… 

Complete mitochondrial genomes of Thai and Lao populations indicate an ancient origin of Austroasiatic groups and demic diffusion in the spread of Tai–Kadai languages

High genetic heterogeneity across the region, with 212 different haplogroups, and significant genetic differentiation among different samples from the same ethnolinguistic group is found, consistently supports the spread of TK languages by demic diffusion.

Complete mitochondrial genomes of Thai and Lao populations indicate an ancient origin of Austroasiatic groups and demic diffusion in the spread of Tai-Kadai languages

Surprisingly, there is significant genetic differentiation within ethnolinguistic groups, calling into question the common assumption that there is genetic homogeneity within ethnic groups.

Reconstructing the Human Genetic History of Mainland Southeast Asia: Insights from Genome-Wide Data from Thailand and Laos

The first detailed insights into the genetic profiles of Thai/Lao ethnolinguistic groups are provided, which should be helpful for reconstructing human genetic history in MSEA and selecting populations for participation in ongoing whole genome sequence and biomedical studies.

Close genetic relationship between central Thai and Mon people in Thailand revealed by autosomal microsatellites

This work found genetic similarity between the central Thai and Mon and weak sub-structuring among Thais from central, northern, and northeastern Thailand and regional allelic frequency on forensic microsatellites may serve as a useful reference for further forensic investigations in both Thailand and Myanmar.

Genetic Structure and Forensic Utility of 23 Autosomal STRs of the Ethnic Lao Groups From Laos and Thailand

The anthropological results revealed the genetic homogeneity of Tai-Kadai speaking Lao groups from Thailand and Laos, consistent with previous studies, while the Austroasiatic speaking groups from southern Laos showed genetic relatedness to both Lao Isan and Khmer.

Forensic and genetic characterizations of diverse southern Thai populations based on 15 autosomal STRs

It is found genetic distinction of the Maniq and sea nomads from the major groups, which were closer to the Malay and central Thais than the other Thai groups.

Genetic structure of the ethnic Lao groups from mainland Southeast Asia revealed by forensic microsatellites

The genetic structure between Laotians and Lao Isan and other ethnic groups from Thailand is explored to clarify historical patterns of admixture between Tai‐Kadai and Austroasiatic speakers, and to expand the forensic reference database for the region.

HLA alleles and haplotypes in Burmese (Myanmarese) and Karen in Thailand.

Overall, the HLA allele and haplotype frequencies detected by polymerase chain reaction sequence-specific primer (PCR-SSP) at five loci at low resolution showed distinct differences between the Burmese and Karen.

Genetic structure of the Mon-Khmer speaking groups and their affinity to the neighbouring Tai populations in Northern Thailand

The Mon-Khmer speaking populations in northern Thailand exhibited the genetic divergence among each other and also when compared to Tai speaking peoples, and the different drift effects and the post-marital residence patterns are the explanation for a small but significant fraction of the genetic variation pattern within and between them.

Mitochondrial DNA Variation of Tai Speaking Peoples in Northern Thailand

The Yuan or Khon Muang in northern Thailand exhibited a close relationship to the Tai groups in South and Southeast China, which supported the immigrant hypothesis and their ancestor's origin, but an admixture between the KhonMuang and the Lawa and Mon, the long existing populations of northern Thailand, needs to be investigated.

Genetic affinity and admixture of northern Thai people along their migration route in northern Thailand: evidence from autosomal STR loci

Different admixture patterns of the KM along the migration route might indicate high heterogeneity among the KM, suggesting other factors, like variation in the timing of admixture with the existing populations may have had an important role.

Mitochondrial DNA-HVR1 Variation Reveals Genetic Heterogeneity in Thai-Isan Peoples from the Lower Region of Northeastern Thailand

The present study investigates genetic variation and genetic structure in three Thai-Isan populations by analyzing mitochondrial DNA variation in hypervariable region 1 and evaluates genetic relationship and admixture between Thai- isan and surrounding populations from Northeastern Thailand, and neighboring countries.

Mitochondrial DNA polymorphisms in Thailand

The D-loop sequences variation, and phylogenetic analysis, suggested that the 9-bp deletion had occurred in a very ancient ancestry of Southeast Asians, although multiple origins of the deletion cannot be ruled out.

Genetic structure of khon mueang populations along a historical yuan migration route in northern thailand

The genetic structure and diversity of the Khon Mueang, who constitute the majority of the current northern Thai populations, is poorly understood. In present study, 433 unrelated individuals from 10

Genetic and Linguistic Affinities between Human Populations in Eurasia and West Africa

This study examines the relationship between genetic distance and linguistic affiliation for five regional sets of populations from Eurasia and West Africa and suggests that linguistic and genetic affiliations will only be correlated under specific conditions, such as where there have been large-scale demic diffusions in the last few thousand years, and relative sedentism in the subsequent period.

Genetic history of Southeast Asian populations as revealed by ancient and modern human mitochondrial DNA analysis.

The 360 base-pair fragment in HVS-1 of the mitochondrial genome were determined from ancient human remains excavated at Noen U-loke and Ban Lum-Khao, two Bronze and Iron Age archaeological sites in

It is demonstrated that speakers of different language families in Europe differ genetically and that this difference remains even after geographic differentiation is allowed for, due to the several factors that bring about spatial differentiation in human populations.

A Microsatellite Guided Insight into the Genetic Status of Adi, an Isolated Hunting-Gathering Tribe of Northeast India

The results support the recent formation of the Adi sub-tribes from a putative ancestral group and reveal that geographic contiguity is a major influencing factor of the genetic affinity among the Tibeto-Burman populations of India.
