    • Agenda Why a global multiplex? Multiplex Configuration Strategy Application-Specific Development and Testing Results − Direct amplification for single source samples − Casework samples Summary11/13/2012 2
    • Why a Global Multiplex? New CODIS Expanded Missing Persons Recommendations ESSL Investigations Increase international data compatibility Why? Increase discrimination power Reduce the likelihood of adventitious matches Increase the number of loci How? Incorporate loci contained in global databases11/13/2012 3

    • What is GlobalFiler™? The GlobalFiler™ Kits are our response to the CODIS Core Loci Working Group’s recommendation to expand the CODIS Core Loci from 13 to 20 required loci and 3 optional loci Originally communicated as a letter to the editor (FSI Genetics) and accepted for publication on April 2011 (revised on Jan 2012) Authored by Doug Hares from the FBI Expectation of a single amplification kit11/13/2012 5

    • Minimizing False Homozygosity Literature reports indicate instances of false homozyosity in the Identifiler®/NGM SElect™ Kits as a result of primer site SNP mutations Eight new SNP-specific primers have been included in the GlobalFiler™ Kits to minimize the occurrence of null alleles in future data sets − A series of SNP-specific primers already exist in the Identifiler®/NGM SElect™ Kits to account for other primer site mutations Locus References D3S1358 Kline et al.
