Y-STR genetic diversity in autochthonous Andalusians from Huelva and Granada provinces (Spain)

Journal: Forensic Science International: Genetics | Year: 2012

Abstract:

Seventeen Y-chromosomal short tandem repeats (STRs) were analyzed in 347 healthy, unrelated, autochthonous males from the Andalusian provinces of Huelva (N = 167) and Granada (N = 180). AmpFlSTR Y-filer PCR Amplification kit (Applied Biosystems) was used to type the Y-STR markers. A total of 156 and 166 different haplotypes for the 17 Y-STR set were detected in Huelva, and Granada, respectively. The same haplotype diversity was found for both samples (0.998 ┬▒ 0.001), and the overall discrimination capacity was 0.904. The most common minimal haplotype (DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393) in both subpopulations was 14-13-16-24-11-13-13, which is also the most frequent haplotype among Atlantic European populations. Comparison analysis using pairwise RST values and Analysis of Molecular Variance (AMOVA) revealed a significant genetic distance between our Andalusian samples and other ones from the northern Iberian fringe (including Basque and Pyrenean populations). However, results from the multi-dimensional scaling analysis (MDS) yielded a well-defined group of Iberian populations separated from the other Mediterranean clusters observed.

Y-STR genetic diversity of Croatian (Bayash) Roma

Journal: Forensic Science International: Genetics | Year: 2008

Abstract:

Seventeen Y-chromosomal short tandem repeats (STRs) (DYS19, DYS385, DYS389I, DYS398II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, GATA H4.1) were typed in DNA samples from 146 unrelated adult Romani Bayash men from eastern and northwestern Croatia. Analysed Croatian Bayash Romani population represents an example of genetically homogenous population characterised by low levels of haplotype diversity and unique haplotype ratio as well as sharing of the same most frequent (founding) haplotype and its close derivatives by more than one third of the analyzed men. Despite almost exclusive sharing of the same minimal haplotype and its closely related derivates on the background of the Indian Y SNP haplogroup H1, we observed considerable level of genetic differentiation of Romani populations across Europe that should not be neglected in forensic statistics.

Y-STR haplotypes in Central Anatolia region of Turkey

Journal: Forensic Science International | Year: 2004

Abstract:

Allele frequencies and haplotypes of the 11 Y-chromosome STRs loci, namely DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS438, and DYS439 were determined in a sample of 113 unrelated males from the Central Anatolia region of Turkey. In the 113 samples 106 different haplotypes were encountered, of which 100 were observed only once. The overall haplotype diversity was 0.9987. In the study, a duplication at locus DYS19 and locus DYS393 was observed. The results demonstrate that these loci will be very useful for human identification in forensic cases and paternity tests in the Central Anatolia region.

Y-STR variation in Albanian populations: implications on the match probabilities and the genetic legacy of the minority claiming an Egyptian descent

Journal: International journal of legal medicine | Year: 2010

Abstract:

Y chromosome variation at 12 STR (the Powerplex® Y system core set) and 18 binary markers was investigated in two major (the Ghegs and the Tosks) and two minor (the Gabels and the Jevgs) populations from Albania (Southern Balkans). The large proportion of haplotypes shared within and between groups makes the Powerplex 12-locus set inadequate to ensure a suitable power of discrimination for the forensic practice. At least 85% of Y lineages in the Jevgs, the cultural minority claiming an Egyptian descent, turned out to be of either Roma or Balkan ancestry. They also showed unequivocal signs of a common genetic history with the Gabels, the other Albanian minority practising social and cultural Roma traditions.
