Article Synopsis
- Mon-Khmer people have been present in northern Thailand since prehistoric times, but were fragmented after the Tai colonization in the 13th century, leading to varying degrees of integration with Tai society.
- Genetic studies show two clusters of modern Mon-Khmer populations: one with limited contact with Tai peoples (Khamu, Lua, Paluang, Htin) and another (Mon, Lawa) that shows significant historical interaction and genetic admixture with Tai groups.
- This genetic blending reflects current inter-ethnic marriages as cultural and geographic barriers have diminished, especially seen in the assimilation of the Karen hill tribe into both Mon-Khmer and Tai genetic pools.
Background: Turner syndrome, a congenital condition that affects 1/2,500 births, results from absence or structural alteration of the second sex chromosome. Turner syndrome is usually associated with short stature, gonadal dysgenesis and variable dysmorphic features. The classical 45,X karyotype accounts approximately for half of all patients, the remainder exhibit mosaicism or structural abnormalities of the X chromosome.

For this reason, it is required to establish and expand the databases that reflect the actual allele frequencies in the population applied. 21,473 complete DNA profiles from Databank samples were used to establish the allele frequency database to represent the population of Hungarian suspects.

- Y-chromosomal short tandem repeats (Y-STRs) are used to test paternal relationships and identify male lineage, but the standard Yfiler set has limitations.
- A study involving 52 centers analyzed 13 rapidly mutating Y-STRs in 14,644 males from 111 populations, leading to over 99% successful individual identification.
- The results showed extremely high haplotype diversity, minimal sharing among populations, and significant improvements in relationship differentiation when using RM Y-STRs compared to traditional methods.
A global analysis of Y-chromosomal haplotype diversity for 23 STR loci.

In a worldwide collaborative effort, 19,630 Y-chromosomes were sampled from 129 different populations in 51 countries. These chromosomes were typed for 23 short-tandem repeat (STR) loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, GATAH4, DYS481, DYS533, DYS549, DYS570, DYS576, and DYS643) and using the PowerPlex Y23 System (PPY23, Promega Corporation, Madison, WI). Locus-specific allelic spectra of these markers were determined and a consistently high level of allelic diversity was observed.
