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 genetics of nine STR loci from Baoan population in NW China

Allele frequencies for the nine short tandem repeat (STR) loci (D3S1358, FGA, TH01, D7S820, VWA, CSF1PO, D5S818, D13S317, TPOX) were determined in a sample of 120 unrelated individuals of the Baoan ethnic group living in northwest China. The values of observed heterozygosity (H), discrimination power (DP), a priori chance of exclusion (CE) and polymorphism information content (PIC) were calculated. All loci were in accordance with Hardy-Weinberg equilibrium (P=0.05). The obtained frequency distributions were compared with other previously reported population data.

Population genetics data of 23 autosomal STR loci for three Populations in United Arab Emirates

In the present study, forensic parameters were estimated for three populations residing in the United Arab Emirates (UAE) including UAE Arabs, Pakistanis and Indians based on the population data of 23 autosomal short tandem repeats (STRs). The UAE Arabs is a vital population to study due to high rates of consanguineous marriages. Therefore, it is essential to estimate the allele distribution and frequencies within this population. In addition, it is crucial to study the largest communities living in the UAE such as Indians and Pakistanis. A total of 1272 blood samples were collected on FTA® cards, comprising of 571 UAE Arabs, 352 Indians and 349 Pakistanis. All of these samples were amplified directly using Verifiler® Express PCR Amplification Kit that focuses on 23 autosomal STR loci, namely D3S1358, vWA, D16S539, CSF1PO, TPOX, D8S1179, D21S11, D18S51, D2S441, D19S433, TH01, FGA, D22S1045, D5S818, D13S317, D7S820, D10S1248, D1S1656, D12S391, D2S1338, D6S1043, Penta D and Penta E loci. The PCR products were electrophoresed on ABI 3500 Genetic Analyzer and analyzed using GeneMapper ID-X v1.4 software. Arlequin v3.5 and PowerStats software were utilized to determine the forensic parameters and population structure using AMOVA. Gene diversity, ranged from 0.67406 (TPOX) to 0.9226 (Penta E) in the UAE Arabs, 0.69955 (TPOX) to 0.9214 (Penta E) in Indian and 0.69853 (TPOX) to 0.921 (Penta E) in Pakistani population. The most discriminating autosomal STR loci observed was Penta E (PD = 0.985), (PD = 0.986), (PD = 0.986) in the UAE Arabs, Indian and Pakistani population, respectively. The obtained results showed the 23 STR loci had a relatively high genetic variation, confirming the suitability for forensic identification and kinship analysis, in the relevant populations. The significance of this study is to build an allelic frequency database for one of the most powerful commercially available STR amplification kits by using the current forensic workflow.

The combined MP and PE for all 15 loci are 3.9 × 10⁻¹⁸ and 0.9999988, respectively. Pairwise comparisons between Northwestern Poland and other Polish populations were performed.

15 STR loci frequencies in the population from Santa Catarina, Southern Brazil

Allele frequencies for 15 short tandem repeats (STR) loci were determined with a sample of 3000 unrelated individuals from the population of Santa Catarina, Southern Brazil. The loci are most commonly used in forensic and paternity testing, being analyzed by the Powerplex 16 (Promega) commercial kit. The data shows that most polymorphic loci were Penta E and FGA. The distributions of the genotypes in the evaluated loci are in Hardy–Weinberg equilibrium. Comparative analyses between our population data and other Brazilian populations are presented. The calculated forensic parameters showed that the loci are useful for the solution of forensic problems in Brazilian Southern region.
