Swiss Caucasian population data for 13 STR loci using AmpFISTR profiler plus and cofiler PCR amplification kits.

Allele and genotype frequencies for the 13 core STR loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, THO1, TPOX, CSF1PO, and D16S539) were determined in a Swiss Caucasian population sample (n = 206) using two commercially available multiplex PCR kits (AmpFISTR Profiler Plus and AmpFISTR Cofiler) and subsequent electrophoresis on an ABI PRISM CE 310 Genetic Analyzer instrument. All loci meet Hardy-Weinberg expectations. In addition, there is little evidence for association of alleles among the 13 loci. The allelic frequency data can be used in forensic analyses and paternity tests to estimate the frequency of a multiple STR locus DNA profile in the Swiss population.     

Swiss Caucasian population data for the STR loci D2S1338 and D19S433 using the AmpFISTR SGM plus PCR amplification kit

Allele and genotype frequencies for the ten STR loci D3S1358, VWA, D16S539, D2S1338, D8S1179, D21S11, D18S51, D19S433, TH01, FGA were determined in a Swiss Caucasian population sample (n=206) using the AmpFISTR SGM Plus Amplification kit. Electrophoresis was carried out on an ABI PRISM CE 310 Genetic Analyzer instrument. Previously, allele frequencies were published for the 13 STR loci D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, THO1, TPOX, CSF1PO and D16S539 for the same samples (n=206) amplified with the AmpFISTR Profiler Plus and Cofiler PCR Amplification kits. Since the results for the eight loci D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, THO1, D16S539 shared between the AmpFISTR SGM Plus, Profiler Plus and Cofiler PCR Amplification kits already are published, only the allele frequencies for the two STR loci D2S1338 and D19S433 are reported in this paper. The two loci meet Hardy-Weinberg expectations. In addition, there is little evidence for association of alleles among the 15 loci (amplified with the Profiler, Cofiler, and SGM Plus amplification kits). The allelic frequency data can be used in forensic analyses to estimate the frequency of a multiple STR locus DNA profile in the Swiss population.

The analysis of three short tandem repeat (STR) loci in the Slovene population by multiplex PCR

Allele frequencies for three tetrameric short tandem repeat (STR) loci D3S1358, HUMVWA, and HUMFGA were determined in a Slovene Caucasian population sample. DNA samples from a total of 221 Slovenes were amplified by multiplex PCR using the commercial kit AmpFISTR Blue (Perkin-Elmer). Separation and detection of the amplified STR fragments were carried out using a 377 automated genetic analyzer (Applied Biosystem Division/Perkin Elmer). Seven alleles at the D3S1358 locus, 8 alleles at the HUMVWA31A locus, and 13 alleles at the HUMFGA locus were observed. A deviation from Hardy-Weinberg equilibrium was observed, only at the HUMVWA31A locus (p = 0.045, exact test). The departure at this locus was not significant after Bonferroni correction. There were no detectable departures between pairwise comparisons of the loci. The combined power of discrimination for all three loci is 0.9998, and the power of exclusion is 0.9526. The observed allele frequencies for the loci D3S1358, HUMVWA31A, and HUMFGA are similar to those in European and U.S. Caucasian populations.

Genetic variation of 13 STR loci in the four endogamous tribal populations of Eastern India

We have analysed 13 autosomal STR loci in four endogamous tribal populations from two eastern states (Orissa and Nagaland) of India. The Gadaba, Kuvi Khond and Lotha Naga populations have not been analysed for microsatellite genetic variation previously. The allele frequencies for all loci are within the range observed in the geographical region and racial background, though some alleles showed greater variation. Departures from the Hardy-Weinberg equilibrium were tested by three methods and two loci (THO1 and TPOX) showed significant departures for all measures in Gadaba and Lotha Naga populations. The exclusion probability and discrimination probability were high for all analysed loci in all populations. There is no evidence for association of alleles among the STR loci studied. This allele frequency information will be useful for forensic, paternity and population genetic studies.

Maine Caucasian population DNA database using twelve short tandem repeat loci

A population study of Caucasians residing in Maine was conducted using the AmpF1STR Profiler PCR Amplification Kit and the AmpF1STR Profiler Plus PCR Amplification Kit (Applied Biosystems Division (ABD) of Perkin Elmer, Foster City, CA). The kits contain the reagents necessary to amplify 12 different STR loci and the gender marker Amelogenin using two multiplex PCR, each containing nine STR loci. Thus, there is an overlap of six STR loci. The 12 STR loci are TH01, TPOX, CSF1PO, D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, and D7S820. These loci represent 12 of the 13 core loci selected by the CODIS STR standardization project. Dye-labeled amplification products were separated and detected using the capillary electrophoresis instrument ABI Prism 310 Genetic Analyzer. Allele frequencies were determined for the 12 STR loci. Statistical analysis of the data included Hardy-Weinburg equilibrium (HWE) analysis, pairwise independence testing, power of discrimination (PD), and probability of exclusion (PE).
