Mixture analysis using SWaP™ SNPs and non-biallelic SNPs

subject

description

Abstract Improved analysis of degraded samples, increased throughput, and a wider choice of typing platforms are some of the significant advantages offered by single nucleotide polymorphism (SNP) genotyping over established short tandem repeat (STR)-based systems. However, DNA mixtures present a considerable problem to SNP analysis as there is currently no generally accepted technique that allows recognition of the presence of a mixed profile or identification of the individual contributors. We present the first demonstration of SNP mixture analysis with an approach based upon the use of two rare subsets of SNPs: SWaP™ SNPs and non-biallelic SNPs and discuss their value for forensic mixture analysis.
