Sexual assault kits make up the majority of operational casework for many laboratories in the United States. Next-generation sequencing offers enhanced technical and analytical capabilities that can aid in processing these kits effectively. This workshop explores how NGS can obtain more information, provide more investigative leads and thus reduce the backlog. A panel of experts will discuss (1) the strengths and limitations of CE and NGS, (2) the value of Y-STRs and SNPs for short and long range familial searches, (3) options for STR and SNP mixture deconvolution, and (4) data interpretation and validation studies to enable seamless implement NGS for sexual assault resolution.
Handouts include development validation studies and implementation strategies.
