This is the Final Summary Overview of the findings and methodology of a research project with the goal of characterizing the performance of a pre-configured panel of ancestry and phenotypically informative SNPs on DNA extracted from a controlled sample of well-documented skeletal cases; and the SNP results were compared with the individual’s self-reported data and the project’s anthropological analysis of ancestry.

| Abstract: |
The study used human remains obtained through the Forensic Anthropology Center (FAC) Body Donation Program at the University of Tennessee, Knoxville. The research produced the following four findings: 1) the SNP chip testing results had a significant decline in accuracy when the call rates were below 70 percent; 2) DNA from blood samples yielded accurate phenotype and ancestry predictions at 10 Ng of input DNA, but bones required at least 250 Ng of DNA to have a call rate over 70 percent; 3) phenotypic information was determined for DNA from about 50 percent of the bone samples and 67 percent of the blood samples at a 6-year postmortem interval; and 4) anthropological assessments were mostly consistent with self-reported ancestry, but the non-metric assessments did not capture the phenotypic variation in human groups. This report advises that the greatest potential gain from this research is the demonstration of a new probative tool to assist in identifying human skeletal remains for the forensic and criminal justice community. Information is provided on the dissemination of project results. 2 tables |
