Implication

Validation study demonstrates high sensitivity and accuracy of a 154-plex STR panel across forensic DNA samples, indicating enhanced resolution for complex kinship and degraded casework.

Key Points

Develop and validate a comprehensive 154-plex MPS STR panel encompassing autosomal, X-, and Y-chromosomal markers for forensic genetic investigations on Illumina and Nanopore platforms.
Constructed a 154-plex STR assay targeting 66 autosomal, 57 Y-chromosomal, and 31 X-chromosomal loci on the Illumina platform, with preliminary testing on Nanopore.
Validated performance per SWGDAM guidelines using standard reference DNAs (9947A, 9948, 2800M), samples from 110 unrelated individuals (N=110), and non-human control species across sensitivity, mixture, inhibitor, and degradation assays.
Generated complete STR profiles at ≥0.5 ng DNA input and maintained >94% accuracy down to 12.5 pg, while successfully recovering 10% minor contributors in mixed samples.
Achieved >90% marker detection in degraded DNA (DI ≤ 6.34), demonstrated resistance to key inhibitors (200 ng/µL humic acid, 100 ng/µL tannic acid, 100 µM hemoglobin), and confirmed human specificity without cross-species amplification.
Concorded with traditional capillary electrophoresis typing while resolving length-identical alleles through sequence-level polymorphisms and flanking single nucleotide polymorphisms.
