“The Linosa Study”: Epidemiological and heritability data of the metabolic syndrome in a Caucasian genetic isolate
Abstract Background and aims Growing evidence suggests that the metabolic syndrome (MetS) has both a genetic and environmental basis. To evaluate the possibility of a further genetic analysis, we estimated prevalence rates and heritabilities for the MetS and its individual traits in the adult population of Linosa, a small and isolated Italian Island in the southern-central part of the Mediterranean Sea. Methods and results The Linosa Study (LiS) group consisted of 293 Caucasian native subjects from 51 families (123 parents; 170 offsprings). The MetS was defined according to NCEP/ATP III criteria and the following prevalence rates were calculated: hyperglycaemia 20.3%; central obesity 34.9%;…
The molecular characterization of a depurinated trial DNA sample can be a model to understand the reliability of the results in forensic genetics
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. …
WITHDRAWN: Corrigendum to ‘Development of an Italian RM Y-STR haplotype database: results of the 2013 GEFI collaborative exercise’ [Forensic. Sci. Int. Genet. 15 (2015) 56-63]
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.
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…
In silico and in vitro comparative analysis to select, validate and test SNPs for human identification.
Abstract Background The recent advances in human genetics have recently provided new insights into phenotypic variation and genome variability. Current forensic DNA techniques involve the search for genetic similarities and differences between biological samples. Consequently the selection of ideal genomic biomarkers for human identification is crucial in order to ensure the highest stability and reproducibility of results. Results In the present study, we selected and validated 24 SNPs which are useful in human identification in 1,040 unrelated samples originating from three different populations (Italian, Benin Gulf and Mongolian). A Rigorous in silico selection of these markers provided …
