Population data of nine STRs of Mexican-Mestizos from Mexico City

One hundred and thirteen individuals were PCR-typed for nine STR loci with the AmpFlSTR Profiler Plus PCR amplification kit, including the following autosomal STRs: D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317 and D7S820. Allele frequencies for each STR were estimated, and they were compared to other populations. Genotype distribution by locus and by two-loci combination was in agreement with Hardy-Weinberg expectations for all nine STRs. For this region of Mexico, the combined probability of exclusion (PE) and power of discrimination (PD) were estimated: PE=99.964% and PD>99.999%.     

Population data for 12 Y-chromosome STRs in a sample from Brescia (northern Italy)

Twelve Y-chromosome STRs--DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439--were typed in a population sample (n=104) of unrelated males from Brescia (northern Italy). A total of 91 haplotypes were identified by the 12 Y-STR loci. The haplotype diversity (98.68%), discrimination capacity (87.50%) and gene diversity were calculated.     

Population data for 16 Y-chromosome STRs in four populations from Pyrenees (Spain)

Population frequencies for the eight Y-STR loci included in the "minimal haplotype" from Y-STR Haplotype Reference Database (YHRD) plus other eight Y-STRs (DYS434, DYS435, DYS436, DYS437, DYS438, DYS439, GATA H4 and GATA A10) were obtained for a sample of 133 males from four main geographical areas in the Pyrenees (Spain): Vall D'Aran (Lérida), Cerdanya (Gerona), Alt Urgell (Lérida) and Jacetania (Huesca). Haplotype diversities were estimated in the four populations.     

Population data on 15 autosomal STRs in a sample from East Timor

Allele frequencies for the fifteen STRs included in the AmpF/STR Identifiler (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, TH01, TPO and VWA) were estimated from a sample of 186 unrelated individuals from East Timor. No deviations from Hardy-Weinberg equilibrium were observed (only after applying the Bonferroni correction in the cases of D2S1338, TPO and D5S818). Genetic parameters of forensic interest were calculated and comparison with geographically nearby populations was performed.     

Population data of nine Y-chromosomal STR loci in northern Poland

Allele and haplotype frequencies of nine Y-chromosome STR loci were determined from a sample of 508 unrelated males from north Poland. Three samples containing insertion polymorphism DYS19 (duplication) and DYS385I/II (triplications) were observed.     

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 data of five STRs in three regions from Portugal

Allele and haplotype frequencies of five chromosome STR loci (CD4, TPO, FES, TH01 and VWA) were determined for unrelated males throughout Portugal. This report presents STR data for three separate regions of Portugal, being the first time that data on the south of the country is presented. This study reveals that the three regions from Portugal are not genetically homogeneous. The north of Portugal presents significant differences in the CD4 locus, when compared with the other two populations. When compared with Madeira and A?ores, the three regions show a different behavior at TPO and VWA loci.     

Population data for 15 Y-chromosome STRs in a population sample from Quito (Ecuador)

Population frequencies for the 9 Y-STR loci included in the "minimal haplotype" from Y-STR Haplotype Reference Database (YHRD), plus other 6 Y-STRs (DYS437, DYS438, DYS439, GATA A7.2, GATA H4 and GATA A10) were obtained for a sample of 120 males from Quito (Ecuador). One hundred and sixteen unique haplotypes were identified within the sample. Haplotype diversity (0.9994) was among the highest in comparison to other populations from Iberia and South-America. Genetic distances were calculated and our sample presented significative differences with all other samples, the lowest values being with a Guinean sample.     

Population data of Y-chromosomal STRs in Lithuanian, Latvian and Estonian males

Data of nine Y-chromosomal STRs, the so called "extended core set", were obtained from 152 unrelated males from Lithuania, 145 from Latvia and 133 from Estonia. The haplotype data reported here have been included into the Y-STR database maintained at the Institute of Legal Medicine, Humboldt-University, Berlin.     

Population data of Y-chromosomal STRs in lithuanian, latvian and estonian males

Data of nine Y-chromosomal STRs, the so called “extended core set”, were obtained from 152 unrelated males from Lithuania, 145 from Latvia and 133 from Estonia. The haplotype data reported here have been included into the Y-STR database maintained at the Institute of Legal Medicine, Humboldt-University, Berlin.     

Population data of nine miniSTR loci in Koreans

For highly degraded DNA samples of forensic casework, new miniSTR systems have been developed to supplement the current STR systems. In the present study, nine miniSTR loci were analyzed in 300 unrelated Koreans using three multiplex PCR systems (multiplex I: D10S1248, D14S1434 and D22S1045; multiplex II: D1S1677, D2S441 and D4S2364; and multiplex III: D3S3053, D6S474 and D20S482), and allele frequencies and forensic parameters were calculated. These data demonstrated that D10S1248, D2S441, D22S1045, D14S1434, and D6S474 are as highly informative as the CODIS STRs suggesting that the miniSTRs could be useful for forensic analysis of degraded DNA.     

Population genetic data of 15 tetrameric short tandem repeats (STRs) in Berbers from Morocco

The allele frequency distribution of 15 short tandem repeats (STR) loci contained in the AmpFlSTR Identifiler PCR Amplification Kit (Applied Biosystems), was determined in two Berber populations from Asni and Bouhria, in Central and Eastern Morocco, respectively. A total of 209 individuals were typed. No deviations from the Hardy-Weinberg equilibrium were observed for Asni at the 15 STRs loci whereas for the Bouhria samples, two loci (D5S818 and TH01) showed significant departures from Hardy-Weinberg expectations (after Bonferroni's correction). All loci are highly polymorphic and population differentiation tests showed that the Moroccan samples from Asni and Bouhria have significant differences in 4 out of 15 loci (D21S11, D7S820, D16S539 and TPOX). The aim of the study was to obtain accurate allele frequencies relevant for forensic applications. Comparative analyses between our population data and other population samples gathered from the literature are also presented.
