A closer look at Verogen's Forenseq™ DNA Signature Prep kit autosomal and Y-STR data for streamlined analysis of routine reference samples.

Massively parallel sequencing (MPS) provides forensic DNA laboratories an option to overcome the limitations associated with CE and current STR assays. Verogen's MPS ForenseqTM DNA Signature kit concomitantly amplifies 27 autosomal, 7 X-, and 24 Y-STRs. In addition, 94 identity, 56 ancestry, and 22 phenotypic-informative SNPs are included for a total of over 200 markers in one multiplex. An internal validation of this platform was conducted using reference samples to investigate whether the Forenseq™ DNA Signature Prep kit, specifically primer panel B, has the capability to provide consistent and accurate typing/sequencing data. The data presented in this report is limited to that corresponding to autosomal and Y-STRs. Results suggest that the system can consistently generate accurate genotyping data when up to 40 high-quality, high-quantity (i.e. 1 ng) single source samples are pooled into a sequencing reaction. The results generated were used to determine appropriate analysis parameters and thresholds for streamlined data interpretation of reference samples. © Published 2018 This article is a U.S. Government work and is in the public domain in the USA.
