Publication of population data of linearly inherited DNA markers in the International Journal of Legal Medicine.
ABSTRACT This manuscript extends on earlier recommendations of the editor of the International Journal of Legal Medicine on short tandem repeat population data and provides details on specific criteria relevant for the analysis and publication of population studies on haploid DNA markers, i.e. Y-chromosomal polymorphisms and mitochondrial DNA. The proposed concept is based on review experience with the two forensic haploid markers databases YHRD and EMPOP, which are both endorsed by the International Society for Forensic Genetics. The intention is to provide guidance with the preparation of population studies and their results to improve the reviewing process and the quality of published data. We also suggest a minimal set of required information to be presented in the publication to increase understanding and use of the data. The outlined procedure has in part been elaborated with the editors of the journal Forensic Science International Genetics.

ABSTRACT: The aim of this study was to contribute new data on autosomal STR and Y-STR markers of the Mayas from Guatemala in order to improve available databases of forensic interest. We analyzed 16 autosomal STR markers in a population sample of 155 indigenous Maya and 17 Y-chromosomal STR markers in the 100 males of the sample. Deviations from Hardy-Weinberg equilibrium and linkage disequilibrium between autosomal STR markers were not observed at any loci. The combined power of exclusion was estimated as 99.9991 % and the combined power of discrimination was >99.999999999999 %. Haplotype diversity of Y-STRs was calculated as 0.9984 ± 0.0018 and analysis of pairwise genetic distances (Rst) supported the Native American background of the population.Deutsche Zeitschrift für die Gesamte Gerichtliche Medizin 05/2015; DOI:10.1007/s00414-015-1195-1 · 2.60 Impact Factor

ABSTRACT: Ten MiniSTR loci were analyzed on 250 unrelated individuals of Punjabi population from Punjab province of Pakistan. The product amplification range is from 65 to 280 bp. Allele frequency for a total of 98 observed alleles is from 0.002 to 0.41. Forensic and paternity statistical parameters were investigated including combined power of discrimination (PD), combined power of exclusion (PE), and cumulative probability of matching (PM) equaled to 0.99999999999824, 0.999824, and 1.75931×10−12, respectively. These MiniSTRs on the basis of high degree polymorphism and fragment size reduction will be highly informative in most of the forensic cases where DNA of the samples is degraded, mass disasters, and dead body identification. Significant differences were observed in all loci when comparing with same STR loci in previously published different world populations. Keywords MiniSTRs . Genetic polymorphism . Forensic .
