History1999 Idea and concept for a centrally curated mtDNA database
Inspection of published data - high error rates
2004 Collaborative EDNAP study on quality of mtDNA sequencingParson et al 2004 FSI - 10% error rate - corrective actions
2006 EMPOP V1 (GMI funded) Development of software tools for QC (e.g. QMN, Parson and Dür 2007 FSIG)
2010 EMPOP V2 (GMI funded)Introduction of alignment-free sequence searches (SAM, Röck et al 2011 FSIG)
2015 EMPOP V3 (GMI funded)Haplogrouping, programming update, new features
2018 EMPOP V4 (EU-funded)Updated search engine, alignment tool (SAM2, Huber et al in prep)
-
New developments
SAM 2Development of software for
automated phylogenetic alignment and consistent nomenclature of mitochondrial DNA sequences
-
Different mtDNA nomenclature between forensic laboratories (and betweenscientific disciplines)
False exclusions in forensic practice
Mitotypes not directly comparable
Need software to harmonize alignment and nomenclature
SAM2 - Motivation
-
Alignment can be ambiguous

VISAGE – Main Goals
1) Known markers + explore new markers on appearance, age and ancestry
2) Design, develop and validate prototype tools
3) Design interpretation software considering combined stats of all information
4) Identify ethical issues and make recommendations
5) Implement in routine casework
6) Training and dissemination
