Massive parallel sequencing of short tandem repeats in the Korean population.

Abstract

STR analysis using capillary electrophoresis has been the most widely used method for forensic DNA typing. Recently, massive parallel sequencing (MPS) technique has been emerging as an innovative tool to supplement or replace the conventional CE process. In this study, we evaluated the application of commercial MiSeqFGx™ forensic signature kit (Illumina Inc., San Diego, CA, USA) in the Korean population, including performance comparison with CE-based STR profiling kits. The genotyping results of 209 unrelated random Korean individuals were summarized according to the International Society for Forensic Genetics guideline. The study revealed that 26 novel sequence variations in autosomal STR were newly found that had not been previously reported in other forensic literature. This indicates that MPS may be an effective supplementary tool for forensic DNA typing and the database to increase the discriminatory power of individual identification.
