GHEP-ISFG collaborative simulated exercise for DVI/MPI: Lessons learned about large-scale profile database comparisons.

The GHEP-ISFG Working Group has recognized the importance of assisting DNA laboratories to gain expertise in handling DVI or missing persons identification (MPI) projects which involve the need for large-scale genetic profile comparisons. Eleven laboratories participated in a DNA matching exercise to identify victims from a hypothetical conflict with 193 missing persons. The post mortem database was comprised of 87 skeletal remain profiles from a secondary mass grave displaying a minimal number of 58 individuals with evidence of commingling.

Spatial assessment of Argentinean genetic admixture with geographical information systems.

In recent years there has been much attention to Argentinean population stratification. We were interested in assessing population stratification from a geographical perspective and summarizing it in form of maps. We mapped the genetic admixture of the extant male population in central and northern Argentina on the basis of forensic Y-chromosomal haplotypes.

Two fathers for the same child: a deficient paternity case of false inclusion with autosomic STRs.

We present a case of deficient paternity with two presumptive fathers analyzed with 19 autosomic short tandem repeats (STRs) and resolved by means of the study of 12 Y-chromosome STRs. Fifteen autosomic STRs consensued from the commercial kit PowerPlex-16 (Promega) were analyzed, and a combined paternity index (PI(com)) of 13,811.215 and a probability of paternity (W) of 99.
