Online reference database of European Y-chromosomal short tandem repeat (STR) haplotypes
2001
The reference database of highly informative Y-chromosomal short tandem repeat (STR) haplotypes (YHRD), available online at http://ystr.charite.de, represents the largest collection of male-specific genetic profiles currently available for European populations. By September 2000, YHRD contained 4688 9-locus (so-called "minimal") haplotypes, 40% of which have been extended further to include two additional loci. Establishment of YHRD has been facilitated by the joint efforts of 31 forensic and anthropological institutions. All contributing laboratories have agreed to standardize their Y-STR haplotyping protocols and to participate in a quality assurance exercise prior to the inclusion of any…

An inconsistency in the nomenclature used for the rapidly mutating (RM) Y-chromosomal short tandem repeat (Y-STR) marker DYS449 was noted in the above paper. In this paper, the DYS449 allele nomenclature introduced by Ballantyne et al. was used, instead of that described by Redd et al. and subsequently adopted by the International RM Y-STR User Group and in the AMPFlSTR® YFiler Plus kit.
DNA Commission of the International Society of Forensic Genetics: recommendations on forensic analysis using Y-chromosome short tandem repeats
2001
Abstract During the past few years the DNA commission of the International Society of Forensic Genetics has published a series of documents providing guidelines and recommendations concerning the application of DNA polymorphisms to the problems of human identification. This latest report addresses a relatively new area, namely Y-chromosome polymorphisms, with particular emphasis on short tandem repeats (STRs). This report addresses nomenclature, use of allelic ladders, population genetics and reporting methods.

Direct evidence for positive selection of skin, hair, and eye pigmentation in Europeans during the last 5,000 y
2014
Significance Eye, hair, and skin pigmentation are highly variable in humans, particularly in western Eurasian populations. This diversity may be explained by population history, the relaxation of selection pressures, or positive selection. To investigate whether positive natural selection is responsible for depigmentation within Europe, we estimated the strength of selection acting on three genes known to have significant effects on human pigmentation. In a direct approach, these estimates were made using ancient DNA from prehistoric Europeans and computer simulations. This allowed us to determine selection coefficients for a precisely bounded period in the deep past. Our results indicate t…
Development of an Italian RM Y-STR haplotype database: Results of the 2013 GEFI collaborative exercise.
2015
Recently introduced rapidly mutating Y-chromosomal short tandem repeat (RM Y-STR) loci, displaying a multiple-fold higher mutation rate relative to any other Y-STRs, including those conventionally used in forensic casework, have been demonstrated to improve the resolution of male lineage differentiation and to allow male relative separation usually impossible with standard Y-STRs. However, large and geographically-detailed frequency haplotype databases are required to estimate the statistical weight of RM Y-STR haplotype matches if observed in forensic casework. With this in mind, the Italian Working Group (GEFI) of the International Society for Forensic Genetics launched a collaborative ex…
