Forensic Sci. Int. Genet. 11, 214–9. A substantially lower frequency of uninformative matches between 23 versus 17 Y-STR haplotypes in north Western Europe. 2014

Larmuseau, M.H.D. et al.

Notes: The authors examined the usefulness of additional Y-STRs in distinguishing between unknown DNA donor and a database sample and for familial searching or estimating the geographical origin of the donor. They generated Y-STR haplotypes for 535 patrilineal-unrelated males from Flanders (Belgium). This geographic region was chosen because the Y-chromosomal variation and distribution are well characterized. By typing an additional 5 Y-STR loci (23 loci compared to 17), the authors were able to better discriminate between men with nearly identical Y-STR haplotypes, with a much lower number of uninformative Y-STR haplotype matches. A 23-locus haplotype was also more valuable for familial DNA searching and estimating the geographical origin of a DNA donor. (4505)

Forensic Sci. Int. Genet. 12, 12–23. A global analysis of Y-chromosomal haplotype diversity for 23 STR loci. 2014

Purps, J. et al.

Notes: The authors typed 19,630 Y-chromosomes from 129 different populations in 51 countries using the PowerPlex® Y23 System, which amplifies 23 Y-STR loci. They observed a consistently high level of allelic diversity and concluded that the loci amplified by the PowerPlex® Y23 System provide substantially stronger discriminatory power than other available kits.
