Forensic utilization of NGS-STRs and evaluation of system efficacy for different kinship identifications

The availability of sequence polymorphism data and the increased number of STR loci could enhance the efficacy of the detection systems for kinship identifications to a certain extent. These results highlight the potential of combining length and sequence polymorphisms of STRs in forensic practice, offering a valuable tool for addressing the challenge of complex kinship identification. Future research should validate these thresholds in casework samples and expand the number of STR loci to enhance the detection efficacy for distant relationships.
