Background: The establishment of a national haplotype database is important for forensic and genetic
applications and requires studying genetic polymorphisms at Y-STR sites. However, the genetic structure of the Eastern Kazakhstan population is poorly characterised.
Aim: To investigate the genetic polymorphisms of 27 Y-STR loci in the Kazakh population from
Eastern Kazakhstan and analyse the population genetic relationships of the Eastern Kazakhs with other
populations.
Subjects and methods: The Yfiler Plus kit was utilised to genotype 246 healthy, unrelated males from
Eastern Kazakhstan. Based on the raw data, haplotype and allele frequencies along with forensic
parameters were calculated, and an MDS plot was constructed.
Results: A total of 207 haplotypes were detected, of which 186 were unique. The haplotype diversity and
discrimination capacity were 0.997 and 0.841, respectively. Population comparisons showed that Eastern
Kazakhs have close genetic relationships with Kazakhs from Xinjiang, China. At the same time, a difference
was found between the studied population and the previous one in the same part of Kazakhstan.
Conclusions: The obtained haplotypes will help to expand the Kazakhstan Y-chromosome reference
database and will be useful for future genetic research and forensic applications.
