Abstract

Population representative short tandem repeat (STR) allele frequencies are crucial for proper probabilistic interpretation of DNA forensic evidence. STR allele frequencies also provide information about the genetic diversity of a given population. The Lebanese population is characterized by the presence of more than 18 religious communities that have high recorded rates of endogamous and consanguineous marriages, where the choice of marriages is mainly influenced by their respective geographical distributions and religious affiliation. These factors could have led to an increase in complex DNA cases, whereby high numbers of STR markers are needed to help clear the case. Allele frequencies for 23 STR loci in the Lebanese population were recently estimated and published. The present study aims at estimating the STR allele frequencies for five supplementary STRs, namely, the LPL, F13B, FESFPS, F13A01, and Penta C STR markers, which are mainly used to resolve complex kinship investigations. A DNA database representative of the Lebanese population that comprises 505 Lebanese unrelated individuals was used to amplify the five STR systems, using the CS7 kit released by Promega. The allele frequencies for these STR systems were estimated, and a significant departure from the Hardy–Weinberg equilibrium was detected after Bonferroni correction for multiple tests at locus LPL, F13A01, and Penta C. The newly added systems appeared to have variation in their discriminative power among Lebanese individuals. Penta C showed the highest power of discrimination, whereas FESFPS showed the lowest power of discrimination. The estimated frequencies and population data could provide local DNA relationship testing laboratories with additional tools that help resolve complex DNA cases. [ABSTRACT FROM AUTHOR]

Abstract

In a worldwide collaborative effort, 19,630 Y-chromosomes were sampled from 129 different populations in 51 countries. These chromosomes were typed for 23 short-tandem repeat (STR) loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, GATAH4, DYS481, DYS533, DYS549, DYS570, DYS576, and DYS643) and using the PowerPlex Y23 System (PPY23, Promega Corporation, Madison, WI). Locus-specific allelic spectra of these markers were determined and a consistently high level of allelic diversity was observed. A considerable number of null, duplicate and off-ladder alleles were revealed. Standard single-locus and haplotype-based parameters were calculated and compared between subsets of Y-STR markers established for forensic casework. The PPY23 marker set provides substantially stronger discriminatory power than other available kits but at the same time reveals the same general patterns of population structure as other marker sets. A strong correlation was observed between the number of Y-STRs included in a marker set and some of the forensic parameters under study. Interestingly a weak but consistent trend toward smaller genetic distances resulting from larger numbers of markers became apparent. (C) 2014 The Authors. Published by Elsevier Ireland Ltd.
