Genetic analysis can help identify victims of mass fatalities when traditional methods cannot be used, or fail to yield conclusive results. Because next-generation sequencing (NGS) has no relevant limit on the number of loci that can be simultaneously analyzed, you can extract the maximum amount of information from evidence or a known reference sample.
Conventional disaster victim identification methods include fingerprints and odontology. Labs also use molecular methods such as DNA analysis and mitochondrial DNA (mtDNA) sequencing with capillary electrophoresis. Sample types processed after a mass fatality event can include bone fragments, tissue, various personal effects containing DNA, and buccal swabs from relatives.
The goal of DNA testing for disaster victim identification is to extract as much genetic information as possible from highly compromised samples. With traditional DNA testing using capillary electrophoresis (CE), choosing one assay often precludes the ability to perform another. Analysts must evaluate the evidentiary material and decide which assay method to perform.
With Illumina NGS technology, these tradeoffs are eliminated. NGS systems such as the MiSeq FGx Forensic Genomics System have no relevant limit on the number of loci that can be analyzed on the same sample in the same run. Every locus can be assayed, including core sets of autosomal, Y and X STRs, and several categories of SNPs. The mtDNA genome can be analyzed in its entirety in a separate run.
For disaster victim identification, Illumina offers a complete, fully validated DNA-to-data solution designed for forensic genomics. Our recommended NGS workflow includes a dedicated library prep kit, customized benchtop sequencing instrument, and an analytical software package to simplify your lab operations.
Illumina sequencing by synthesis (SBS) technology on the MiSeq FGx Forensic Genomics System combines multiple tests in a single analysis. Achieve high resolution and exceptional accuracy from as little as 1 ng of DNA—even with complex mixtures or degraded DNA.
