Introduction of an single nucleodite polymorphism-based “Major Y-chromosome haplogroup typing kit” suitable for predicting the geographical origin of male lineages
The European Consortium "High-throughput analysis of single nucleotide polymorphisms for the forensic identification of persons--SNPforID", has performed a selection of candidate Y-chromosome single nucleotide polymorphisms (SNPs) for making inferences on the geographic origin of an unknown sample. From more than 200 SNPs compiled in the phylogenetic tree published by the Y-Chromosome Consortium, and looking at the population studies previously published, a package of 29 SNPs has been selected for the identification of major population haplogroups. A "Major Y-chromosome haplogroup typing kit" has been developed, which allows the multiplex amplification of all 29 SNPs in a single reaction. A…
Forensic validation of the SNPforID 52-plex assay.
The advantages of single nucleotide polymorphism (SNP) typing in forensic genetics are well known and include a wider choice of high-throughput typing platforms, lower mutation rates, and improved analysis of degraded samples. However, if SNPs are to become a realistic supplement to current short tandem repeat (STR) typing methods, they must be shown to successfully and reliably analyse the challenging samples commonly encountered in casework situations. The European SNPforID consortium, supported by the EU GROWTH programme, has developed a multiplex of 52 SNPs for forensic analysis, with the amplification of all 52 loci in a single reaction followed by two single base extension (SBE) react…
Moors and Saracens in Europe: estimating the medieval North African male legacy in southern Europe.
To investigate the male genetic legacy of the Arab rule in southern Europe during medieval times, we focused on specific Northwest African haplogroups and identified evolutionary close STR-defined haplotypes in Iberia, Sicily and the Italian peninsula. Our results point to a higher recent Northwest African contribution in Iberia and Sicily in agreement with historical data, southern Italian regions known to have experienced long-term Arab presence also show an enrichment of Northwest African types. The forensic and genomic implications of these findings are discussed.

Analysis of 29 Y-chromosome SNPs in a single multiplex useful to predict the geographic origin of male lineages
Abstract The European Consortium “High throughput analysis of single nucleotide polymorphisms for the forensic identification of persons—SNPforID” has performed a selection of candidate Y-chromosome SNPs (single nucleotide polymorphisms) for making inferences on the geographic origin of an unknown sample. A “Major Y chromosome haplogroup typing kit” has been developed, which allows the multiplex amplification of 29 SNPs in a single reaction followed by a single base extension (SBE) reaction (minisequencing) and separation of the resulting extension products by capillary electrophoresis.
Study of eight novel Y-chromosome STRs in a sample from Valencia (East of Spain): analysis of gene and haplotypes frequencies
Because of the great interest in Y-chromosome polymorphisms not only in the forensic field but also in evolutionary studies, the number of described Y-chromosome markers has been increased considerably in the recent literature. During the last few years, new Y-chromosome polymorphisms have been described, including binary polymorphisms, microsatellites and minisatellites. In this study, eight recently described tetranucleotide microsatellites have been analysed: DYS434, DYS437, DYS439, Y-GATA A7.1, Y-GATA A7.2, Y-GATA A.10, Y-GATA C4 and Y-GATA H4. Gene and haplotype frequencies have been estimated in the Valencian population, to determine highly informative haplotypes, using these new Y-ST…
