Population Genetic data for 15 Autosomal STR markers in Eastern Turkey

Area of Science:

• Forensic Genetics
• Population Genetics
• Human Identification

Background:

• Forensic investigations rely on accurate genetic markers for individual identification.
• Understanding population-specific allelic frequencies is essential for robust forensic analysis.
• Short tandem repeat (STR) loci are widely used in human identification and paternity testing.

Purpose of the Study:

• To determine the allelic frequency distribution of 15 forensic STR loci in an Eastern Turkish population.
• To estimate the statistical genetic parameters relevant for forensic applications.
• To compare population data from Eastern Turkey with 12 other countries.

Main Methods:

• Analysis of 15 STR loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, FGA) in 802 unrelated individuals.
• Calculation of allele frequencies and forensic statistical parameters.
• Comparative analysis of allele frequencies with international population datasets.

Main Results:

• Comprehensive allelic frequency data for 15 STR loci in the Eastern Turkish population were established.
• The study estimated the expected performance of these loci for personal identification and paternity testing.
• Significant variations in allele frequencies were observed when comparing Eastern Turkey with other populations.

Conclusions:

• The 15 STR loci analyzed are highly informative for forensic applications in Eastern Turkey.
• The generated data will enhance the accuracy of genetic profiling for identification and paternity testing in this region.
• Population comparisons highlight the importance of region-specific genetic databases for forensic science.
