In a previous study, a new set of Y-chromosome short tandem repeats, the OSU 10-locus set (MPM1 and MPM2), was shown to have a higher discrimination power when evaluated against the 10 SWGDAM loci on a common population panel. Here, we describe the optimization of the multiplex reactions using dye-labeled primers followed by performance evaluations. The loci exhibited high precision, human male specificity, reliability in different body fluids, high sensitivity, stability, and the ability to amplify nonprobative casework and mixture samples.

One set of loci, designated the OSU 10-locus set, comprises variable, single copy, male-specific loci that are dispersed across the Y-chromosome. Parallel evaluations were performed using the 10 Y-chromosome loci most frequently used for forensic analysis, the loci chosen as the SWGDAM Y-STR loci.
