Forensic validation of Y-chromosome STR polymorphisms in Italy: the GE.F.I. collaborative database

2003

Abstract Haplotype data of 1176 Italian males from 10 regions were obtained as a part of a collaborative validation exercise. Individual data are available at http://www.gefi-forensicDNA.it .

The molecular characterization of a depurinated trial DNA sample can be a model to understand the reliability of the results in forensic genetics

2014

The role of DNA damage in PCR processivity/fidelity is a relevant topic in molecular investigation of aged/forensic samples. In order to reproduce one of the most common lesions occurring in postmortem tissues, a new protocol based on aqueous hydrolysis of the DNA was developed in vitro. Twenty-five forensic laboratories were then provided with 3.0 μg of a trial sample (TS) exhibiting, in mean, the loss of 1 base of 20, and a molecular weight below 300 bp. Each participating laboratory could freely choose any combination of methods, leading to the quantification and to the definition of the STR profile of the TS, through the documentation of each step of the analytical approaches selected. …

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.

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…
