Aim:
To determine allele frequencies' distribution for 15 short tandem repeat (STR) loci in a population sample of 1910 unrelated individuals from the region of Wallachia, South Romania.
Methods:
DNA was isolated using Chelex 100 method and an adapted version of AGOWA mag DNA Isolation Kit Sputum. Polymerase chain reaction amplification was done using AmpFlSTR Identifiler kit (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA). For DNA typing, ABI PRISM 3100 Genetic Analyzer was used. Genetic parameters of forensic interest were calculated and comparisons with geographically close populations were performed.
Results:
With the exception of vWA locus (P=0.001), no other significant deviations from Hardy-Weinberg expectations were found. Single locus comparisons with data on geographically close populations showed significant differences between the population of Wallachia and the population of Bucharest area, Greece, Turkey, Italy, Hungary, Belarus, and Poland, but no differences were found from the population from Croatia and Serbia.
Conclusion:
According to 15 analyzed STR loci, the population of Wallachia region was found to be genetically more similar to Slavic populations of Croatia and Serbia than to other surrounding populations.
