Forensic testing has become more precise with the introduction of next generation sequencing technology, by providing more insight from standard PCR forensic DNA methods, with much greater resolution than previously possible, in a single targeted assay.
Next Generation Sequencing in Human Identification
NGS is Invaluable for human identification, as it is able to resolve Short Tandem Repeats alleles that are identical by size but different by sequence; to provide increased resolution of mixed DNA samples; and the potential to recover additional information from low level and degraded samples.
DNA Crime Stain Analysis
When DNA is too degraded for STRs to yield conclusive results, identity-specific SNPs can provide additional means of identification. Biogeographical informative SNPs and phenotype informative SNPs, which estimate traits such as hair and eye color, help sketch a physical description and generate leads.
When DNA is too degraded for STRs to yield conclusive results, identity-specific SNPs can provide additional means of identification. This results in a more superior analysis of these challenging samples and turn cold cases into hot leads using the phenotypic and biographic markers.
Disaster Victim Identification
Forensic Genetic Genealogy
FGG combines genetic and genealogy methods to identify people through relatives. The results provide investigative intelligence that exonerates the innocent, matches adoptees, and creates leads for cold cases. FGG is particularly useful when traditional methods are inconclusive, or all other options are exhausted.
