Genetic profile of a multi-ethnic population from Guiné-Bissau (west African coast) using the new PowerPlex 16 System kit

Allele and haplotype frequencies of 15 chromosome STR loci included in the kit PowerPlex16 System from Promega, were determined in a sample of unrelated males from Guiné-Bissau, a country from the west African coast. All individuals were subjected to an interview in order to make sure that their ancestors belonged to the same ethnic group. This way we intended to look for possible inter-ethnic differences. PowerPlex 16 includes STRs not studied before in any multi-ethnic population. The kit includes two new allele markers (Penta D and Penta E), which are very useful either in forensics or population genetic studies. The Guinean population presents significant differences when compared with other African populations.     

Genetic polymorphism of 14 non-CODIS STR loci for forensic use in southeast China population

We investigated 14 polymorphic STR loci (D1S2142, D2S1360, D3S1545, D7S1517, D10S2325, D12S391, D13S1492, D14S306, D15S659, D16S3253, D18S1270, D19S253, D20S470, D21S1437) which are not included in the standard sets of forensic loci (CODIS) in a sample of 216 unrelated healthy southeast Chinese individuals. The studied loci were highly informative and did not show departures from Hardy-Weinberg equilibrium. The accumulated powers of discrimination and power of exclusion for the 14 loci were 99.9999999999 and 99.999998%, respectively. No linkage was observed between the 14 loci and the traditional set of STR markers included in commercially available kits (the AmpFLSTR IdentifilerTM 15 System loci). We thus considered the studied 14 STRs are informative and when necessary, can be used as the candidate genetic markers in the study and application in genetics and forensic practice.     

Genetic profile of the Madeira Archipelago population using the new PowerPlex16 System kit

Allele and haplotype frequencies of 17 chromosome STR loci, 15 of them included in the kit PowerPlex 16 System from Promega, were determined in a sample of unrelated males from Madeira and Porto Santo Islands. PowerPlex 16 includes STRs not studied before in the Madeira population. The-kit includes two new allele markers (Penta D and Penta E), which proved to be extremely useful for paternity testing (PD = 0.952 and 0.977, respectively). The study revealed that the Madeira population does not differ from that of the north Portugal. Nevertheless, some loci presented alleles found in sub-Saharan and North European populations which were not reported so far in Portugal.     

Genetic profile of the Açores Archipelago population using the new PowerPlex 16 system kit

Allele and haplotype frequencies of 16 chromosome STR loci, 15 of them included in the Kit PowerPlex16 System from Promega were determined in a sample of unrelated males from the A?ores Archipelago. All subjects were subjected to an interview in order to make sure that their ancestors belonged to the same island at least back to three generations. This way we intended to look for possible inter-islands differences. PowerPlex16 includes STRs not studied before in the A?ores population. The Kit includes two new allele markers (Penta D and Penta E), which proved to be extremely useful for paternity testing (PD=0.921 and 0.971, respectively). The study revealed that the A?ores population is considerable different from the previous studied Madeira population, but does not differ from that of the north Portugal. Nevertheless, some loci presented alleles not previously reported for Portugal.

Genetic diversity at two pentanucleotide STR and thirteen tetranucleotide STR loci by multiplex PCR in four predominant population groups of central India

Genetic diversity study at STR loci in 208 individuals belonging to two backward groups, one caste and one tribal community of Central India called "Chhattisgarh" has been carried out to evaluate significance of Powerplex System loci in human identification and population diversity. Populations are Agharia (72), Satmani (50), Dheria Gond (36) and Teli (50). Fifteen loci (Powerplex 16 Kit) studied are Penta E, D18S51, D21S11, THO1, D3S1358, FGA, TPOX, D8S1179, vWA, Amelogenin, Penta D, CSF1PO, D16S539, D7S820, D13S317 and D5S818. The studied penta nucleotide STR (two) and 13 tetranucleotide (CODIS ) STR are found to be highly polymorphic genetic markers in all studied populations. Most common allele for the four studied population has been found to be same at THO1 (allele 9), D8S1179 (allele 14), CSF1PO (allele 12), Penta E (allele 11) and D16S539 (allele 11). Penta E is found to be most polymorphic (PD=0.89373) among studied 15 STR loci in four populations of Central India.     

Allele frequencies of 15 STRs in the Calchaqui Valleys population (North-Western Argentina)

Allele frequencies for 15 short tandem repeat (STR) loci were obtained from a sample of 110 individuals from the Calchaqui Valleys population (North-Western Argentina). The combined power of exclusion and combined power of discriminating for the 15 tested STR loci were 0.999964 and 0.9999999999999998, respectively. Matching probability was 1 in 4.58 × 10(15). Therefore, it may be concluded that the set of 15 STRs included in the AmpF STR Identifiler kit, represents a powerful tool for forensic applications, paternity testing and population genetics studies in the Calchaqui Valleys population.
