Bio: Lutz Roewer received his PhD in molecular biology in 1990 and holds a full professorship for forensic genetics since 2008 at the Institute of Legal Medicine and Forensic Sciences, Charité-Universitätsmedizin Berlin, Germany. Currently he is head of the Department of Forensic Genetics at the Charité. Lutz was awarded the scientific price of the DGRM (Deutsche Gesellschaft für Rechtsmedizin) in 1990 and 1998 and the scientific prize of the ISFG (International Society of Forensic Genetics) in 1999 for the development of the Y-STR haplotyping method. LR is founder and curator of the YHRD. His major research interest is the molecular and population genetics of the Y chromosome with regard to its forensic application. Another research line is the evolution and demography of indigenous populations in South and North America. He was a member of field expeditions in Argentina, Taiwan and Ecuador.
In this webinar, Dr. Lutz Roewer will discuss the results from a large collaborative project initiated in September 2012 to collect, analyze, database and publish population data of 23 Y-STR locus haplotypes (PowerPlex® Y23 System which was released in August 2012).
As many as 18,863 haplotypes from 127 populations were gathered within the 8 months of the collection phase of the project. Allele and haplotype frequencies as well as diversities were calculated per country, ethnic group and continent. Data regarding the discrimination indices for AmpFLSTR® Yfiler® PCR Amplification Kit and PowerPlex® Y23 System profiles will be shared. The creation of a large global reference database for the PowerPlex® Y23 haplotype format assists forensic labs with the implementation of high-resolution Y chromosome diagnostics in their workflow.
