The concordance of length- and sequence-based STRs used in forensic markers with guidance for practice

Abstract

AbstractNext-generation sequencing (NGS) technology has shed light on every aspect of genetic discoveries, including forensic genetics. The Miseq® FGx Forensic Genetic System (Verogen) is one of the pioneering forensic NGS that provided a complete system from library preparation to data analysis. The system has been validated by several studies and led to a more practical aspect. Short tandem repeat (STR) is a well-established marker that was designed specifically for human individualization. Since NGS provides different data from fragment analysis, a new STR nomenclature is established to make NGS backward compatible with the previous data. In this study, Thai population were used to evaluate the Miseq® FGx Forensic genetic system (Verogen) in practical aspect, including concordance study and forensic population parameters. In summary, we purposed a practical guideline for sequence-based STRs.
