Allelic frequency distribution of 17 STRs from Identifiler and PowerPlex-16 in Central Portugal area and the Azores archipelago

This study analyzes the allelic frequency distribution of 17 STRs contained in the AmpFlSTR Identifiler (Applied Biosystems) and PowerPlex16 System (Promega) commercial kits for two large population samples from the Azores archipelago (Portugal) (N=475) and from Central Portugal (N=2125). Likewise, it includes a comparative study among the population groups analyzed in this paper and those which history points out as originating from the first settlers of the Azores. All loci were highly polymorphic. The Central Portuguese area and the Azores archipelago population samples are in Hardy-Weinberg equilibrium for the 17 markers analyzed.

A study on ten short tandem repeat systems: African immigrant and Spanish population data.

This work presents the results obtained from a genetic-population study for the D1S1656 system in the population of Southwest Spain (Huelva, Cádiz and Sevilla), Spaniards of Caucasian origin from North Africa (Ceuta), as well as in the black Central West African and Moroccan immigrant populations in Spain. The results of a study of the autochtonous population of the Canary Islands (n=138), and immigrant Central West African populations in Spain (n=132), obtained for nine short tandem repeat (STR) loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820), as well as the amelogenin locus, all contained in Profiler Plus (Perkin-Elmer) PCR amplification kits, are also presented. Except for the FGA and VWA data on immigrant Central West African populations in Spain, no deviations from the Hardy-Weinberg equilibrium were detected.

Distribution of Y-chromosomal haplotypes in the Central Portuguese population using 17-STRs

17 Y-chromosome STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS456, DYS391, DYS392, DYS393, DYS385 a/b, DYS458, DYS439, DYS635, GATA H4.1, DYS437, DYS438 and DYS448) were determined for 303 unrelated males, living in Central Portugal, using the AmpFlSTR YFiler PCR Amplification kit (Applied Biosystems). A total of 287 different haplotypes were found, 272 being unique. The overall haplotype diversity (HD) was determined as 0.9996, a value similar to other YFiler data sets. Y-STR polymorphisms in Central Portugal population, using YFiler, provide a powerful discrimination tool for routine forensic applications.

Analysis of Y-chromosomal haplotypes and haplogroups distribution in a population sample from Portugal (central area)

Abstract The aim of this study was to analyse the distribution of Y-chromosomal haplotypes and haplogroups found in central Portugal. In this work, we analysed 102 unrelated individuals of central Portugal. Combining the allelic state of 10 biallelic markers (YAP, SRY-8299, 92R7, 12f2, SRY-1532, SRY-2627, Tat, SY81, M9, LLY22g), we defined the haplogroup to which each sample belonged. Y-chromosomal haplotypes were defined by 16 Y-Short Tandem Repeats (STR) (DYS19, DYS3855 a/b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, GATA A10, GATA C4 and GATA H4). This population study defined 8 different haplogroups and 101 different haplotypes, where 100 haplotypes were unique and 1 was found in two apparently unrelated individuals, both belonging to the same haplogroup.
