Population genetics of 17 Y-chromosomal STR loci in Japanese

Haplotypes and allele frequencies of 17 Y-chromosomal short tandem repeat (Y-STR) markers were examined using the AmpFlSTR Yfiler PCR Amplification Kit (Applied Biosystems) in a population sample of 1166 Japanese male volunteers in 6 prefectures: Miyagi, Yamagata, Osaka, Tottori, Fukuoka, and Okinawa. A total of 1058 haplotypes were observed from 1166 males, and the most common haplotype detected in 12 males had a frequency of 1.03% and the discrimination capacity was 0.907. The R_ST analysis showed statistically significant differences between Okinawa and the other subpopulations.

Population data of Y-chromosomal STRs in Russian males of the Primorye region population

Data of eight Y-chromosomal STRs, the so called "minimal core set", were obtained from 152 unrelated males of the Primorye region of Russia. The allelic frequencies correspond to other European populations. The background is a settlement of males from the European part of Russia, Ukraine and other states which were included in the former western part of the Soviet Union. On the other hand the distribution of the most frequent haplotypes differs to the Ukraine and Russian population. The most frequent haplotype was obtained five times in the population corresponding to 3.3%. The haplotype data reported here have been included into the Y-STR database maintained at the Institute of Legal Medicine, Humboldt-University, Berlin.

Population genetics of 30 insertion-deletion polymorphism in polish Populations

The Investigator DIPplex® kit (Qiagen) contains components for the simultaneous amplification and analysis of 30 biallelic autosomal InDels and amelogenin. The objective of this study was to estimate the diversity of the 30 markers in a Polish population sample (N = 389) and to evaluate their usefulness in forensic genetics. The DIPplex genotype distributions showed no significant deviation from Hardy-Weinberg rule expectations (Bonferroni corrected). The mean observed heterozygosity value is 0.4611, and the combined Matching Probability value is 1.08x10⁻¹³. The investigated marker set has been confirmed as a potential extension to standard STR - based kits or a separate informative system for individual identification and kinship analysis.

Population genetic study in two Transylvanian populations using forensically informative autosomal and Y-chromosomal STR markers

Our study provides population genetic data on two population samples collected in a Hungarian speaking region of Transylvania, Romania. Allele frequency and profile databases were generated on 17 autosomal STR loci (D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, VWA, FGA, TH01, TPOX, CSF1PO, Penta E and Penta D) as well as at the 12 European Y-STR extended haplotype loci (DYS19, DYS389-I/II, DYS390, DYS391, DYS392, DYS393, DYS385 loci, DYS437, DYS438 and DYS439). Data were compared to a Central Hungarian (Budapest region) population sample [B. Egyed, S. Füredi, M. Angyal, L. Boutrand, A. Vandenberghe, J. Woller, Z. Padar, Analysis of eight STR loci in two Hungarian populations, Forensic Sci. Int. 113 (2000) 25-27] that was used as a reference group of the Hungarian population. Calculating the F(ST) indices and with the pairwise comparisons of interpopulation molecular variance (AMOVA) the two populations from Transylvania could be fit into the Hungarian population data showing less substructuring effects as compared to the previous findings in Hungary [B. Egyed, S. Füredi, M. Angyal, L. Boutrand, A. Vandenberghe, J. Woller, Z. Padar, Analysis of eight STR loci in two Hungarian populations, Forensic Sci. Int. 113 (2000) 25-27; B. Egyed, S. Füredi, M.
