QIAGEN's HDplex STRs: Their Application to Forensic Analyses, Discrimination Power, and Patterns of Global Variation
The core short tandem repeats (STRs) in worldwide use have served the forensic analyst very well for many years. Further, recent expansions of European Standard STR sets plus ongoing discussions to extend CODIS have brought powerful upgrades to the battery of core markers available. However, there are still scenarios when supplementary STRs could enhance the data necessary for interpreting complex forensic patterns: making safer inferences about relatedness across distant relationships in deficient pedigrees, and in the not too distant future, improving the specificity of familial searching or expanding the points of reference to better interpret mixed profiles.
The QIAGEN HDplex Kit contains 9 completely novel STRs in addition to ESS or CODIS D12S39, D18S51 and SE33 markers. On an average, these 9 novel STRs provide higher powers of discrimination than kits using the core loci alone.
This webinar will outline the completed studies on worldwide patterns of variability in the 12 novel HDplex STRs and their ability to enhance the power of paternity analyses when combined with existing markers.
It will also describe the upgraded pop.STR allele frequency browser which provides data for 23 core STRs plus a total of 28 supplementary STRs in 56 global populations.
