Species identification was carried out by nucleotide sequence analysis of the cytochrome b (cytb) gene. The aim of the study was to identify biological specimens from diverse vertebrate animals by extracting and amplifying DNA from 44 different animal species covering the 5 major vertebrate groups (i.e. mammals, birds, reptiles, amphibians and fishes). The(More)
Determination of sex using the amelogenin sex test is well established in the forensic field especially for casework and DNA databasing purposes. The sex test is part of commercially available PCR kits. Among 29, 432 phenotypic male individuals stored in the Austrian National DNA database, 6 individuals were found to lack the amelogenin Y-specific PCR(More)
Y-chromosomal STR haplotypes were determined from a sample of 135 unrelated men and 70 sons from Tirol (Austria) using the AmpFlSTR Yfiler PCR amplification kit (Applied Biosystems) that coamplifies 17 Y-STRs. The panel of markers includes the 9-loci European minimal haplotype (minHt) and, in addition, the markers DYS437, DYS438, DYS439, DYS448, DYS456,(More)
DYS464 is a multi-copy STR system with four positions on the Y-chromosome (DYS464a, b, c, and d) which was recently identified and characterized [Forensic Sci. Int. 130 (2002) 97]. The aims of our study were to perform a population study, to estimate the mutation rate and an extensive sequence analysis in order to confirm the nomenclature. Fourteen(More)
Short tandem repeat (STR) typing is the most powerful method for determining the origin of a sample for a number of molecular disciplines such as medical genetics, population genetics, tumor analysis, transplantation medicine, or forensic crime scene analysis. STR alleles are routinely differentiated based upon their fragment size by electrophoresis under(More)
In a worldwide collaborative effort, 19,630 Y-chromosomes were sampled from 129 different populations in 51 countries. These chromosomes were typed for 23 short-tandem repeat (STR) loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, GATAH4, DYS481, DYS533, DYS549, DYS570, DYS576,(More)
The entire mitochondrial DNA control region (~1122 bp) of 270 blood samples (135 mother-child pairs) was determined by direct sequencing. Overall, 135 ‘generational events’ were screened and within these, 20 mother-offspring pairs demonstrated more than 1 mtDNA haplotype. In 13 families, differences in the haplotypes between mother and offspring were(More)
We investigated 15 polymorphic short tandem repeat (STR) loci (D1S1656, D7S1517, D8S306, D8S639, D9S304, D10S2325, D11S488, D12S391, D14S608, D16S3253, D17S976, D18S1270, D19S253, D20S161, and D21S1437) which are not included in the standard sets of forensic loci. The markers were selected according to the complexity of the polymorphic region: Of the 15(More)
The European DNA profiling group (EDNAP) mtDNA population database (EMPOP) is an international collaborative project between DNA laboratories performing mtDNA analysis and the DNA laboratory of the Institute of Legal Medicine (GMI) in Innsbruck, Austria. The goal is to set up a directly accessible mtDNA population database, which can be used in routine(More)
Y-chromosomal short tandem repeats (Y-STRs) are useful forensic DNA markers in investigation of sexual assault cases when a mixture of male and female DNA (e.g., in vaginal swabs) is present in a sample, especially when DNA of the male contributor is present only in very small amount compared to the DNA of the female victim. With autosomal STR analysis of(More)
