Genetic Studies in 5 Greek Population Samples Using 12 Highly Polymorphic DNA Loci

Two minisatellite (D1S80, D17S5) and 10 microsatellite (.D2S1328, TPO, D3S1358, D9S926, DUS2010, THOl, VWF, FES, D16S310, and D18S848) polymorphic loci were analyzed in 5 Greek population groups (eastern Macedonia, central Macedonia, Thessaly, Epirus, and Greeks from Asia Minor) using the polymerase chain reaction. The genotypes at these loci conformed to Hardy-Weinberg equilibrium, and pairwise comparisons between them were in agreement with the expectation of independence between loci. This along with the low values of the coefficient of gene differentiation (GST) and the high heterozygosity levels of all loci allows the use of allele frequency data from the 12 hypervariable DNA markers for medicolegal casework in the Greek population groups studied. The small genetic distances indicate a genetic affinity among the 5 population samples. However, a few markers seem to allow some discrimination among the groups. No significant differences with other European populations were found for the loci studied
