Diversity of nuclear short tandem repeat loci in representative sample of North-eastern Bosnian and Herzegovina population

Abstract

Diversity of nuclear microsatellite markers were analyzed in a reference sample of the population of northeast Bosnia and Herzegovina. 437 samples taken from unrelated individuals were processed and three samples of paternity proof were shown. Detection effectiveness profile of the research, points to a valid choice of method of extraction, amplification and genotyping short tandem repeat (STR) loci with PowerPlextm16 kit. Genetic analysis of allelic variants of the 15 STR loci PowerPlextm16 kit detected 17 samples determined as rare allelic variants or microvariants. Samples were divided into 15 different allelic variants at 7 different loci, and are: in locus D7S820, D16S539, D3S1358, D18S51, PENTA D, PENTA E and in locus vWA. Genetic analysis of mutations in cases of paternity determined three examples of single-step mutations in the loci FGA, Penta D and D3S1358. Genetic analysis of observed STR loci detected three allelic variant of genotype combination 7/10/11.3 in locus D7S820 Type II. Population genetic analysis of STR loci in a representative sample of the population of northeast Bosnia and Herzegovina included the application of the assessment tests of within-population genetic diversity and interpopulation diversity, as well as genetic differentiation between populations: North-eastern Bosnia and Herzegovina (BH) and BH general reference, then the Croatian population, Macedonian, Serbian and Slovenian. Based on the result analysis of specific forensic parameters, it can be assumed that the most informative marker is PENTA E for population genetic analysis and forensic testing in the population of northeast Bosnia and Herzegovina. Research results fit regional STR database of this part of Europe.
