Human identification with STRs and SNPs

Simultaneously sequence multiple forensic STRs and SNPs in one test

Simplified STR & SNP Analysis

Many forensic labs currently utilize PCR and capillary electrophoresis (CE)-based methods to analyze short tandem repeat (STR) markers and other polymorphisms. However, sequencing STRs grants an additional level of resolution for determining differences between individuals, including the ability to see intra-STR single nucleotide polymorphisms, or SNPs. SNPs can be used for identification when DNA is too degraded for STR analysis, or to provide physical and biogeographical estimation for investigative intelligence.

Benefits of SNP & STR Analysis with NGS


  • STR sequencing can resolve alleles of identical size, but different sequence
  • High-throughput sequencing lets you simultaneously analyze multiple polymorphisms
  • Multiple STR types can be analyzed at once, without the need for re-testing
    SNPs provide investigative intelligence

From DNA to Identification

When human identification matters, you need a technology that generates powerful investigative intelligence from a DNA sample. Verogen offers a portfolio of capabilities exclusive to the MiSeq FGx Forensic Genomics Solution, including:
  • Forensic genetic genealogy—Expand your network of information to identify an individual
  • Mitochondrial DNA sequencing—Extract more answers from challenging samples
  • STRs and SNPs sequencing—Translate samples into physical traits

This overview showcases how these unique capabilities advance DNA analysis from generating a profile to providing a human identification.

STR and SNP Sequencing Workflow

Verogen offers a complete, fully validated DNA-to-data solution designed for forensic genomics. First, forensically relevant STRs and SNPs are simultaneously PCR amplified, with indexed adapters incorporated into each amplicon in a separate round of PCR.
Subsequent DNA cluster generation and sequencing by synthesis is performed on the MiSeq FGx Instrument. Finally, analyze and interpret your sequencing data off-line using ForenSeq Universal Analysis Software.
