Abstract
BackgroundMitochondrial DNA (mtDNA) is widely being used for population genetics, forensic DNA fingerprinting and clinical disease association studies. The recent past has uncovered severe problems with mtDNA genotyping, not only due to the genotyping method itself, but mainly to the post-lab transcription, storage and report of mtDNA genotypes.DescriptioneCOMPAGT, a system to store, administer and connect phenotype data to all kinds of genotype data is now enhanced by the possibility of storing mtDNA profiles and allowing their validation, linking to phenotypes and export as numerous formats. mtDNA profiles can be imported from different sequence evaluation programs, compared between evaluations and their haplogroup affiliations stored. Furthermore, eCOMPAGT has been improved in its sophisticated transparency (support of MySQL and Oracle), security aspects (by using database technology) and the option to import, manage and store genotypes derived from various genotyping methods (SNPlex, TaqMan, and STRs). It is a software solution designed for project management, laboratory work and the evaluation process all-in-one.ConclusionsThe extended mtDNA version of eCOMPAGT was designed to enable error-free post-laboratory data handling of human mtDNA profiles. This software is suited for small to medium-sized human genetic, forensic and clinical genetic laboratories. The direct support of MySQL and the improved database security options render eCOMPAGT a powerful tool to build an automated workflow architecture for several genotyping methods. eCOMPAGT is freely available at http://dbis-informatik.uibk.ac.at/ecompagt.

We present a new and extended version of eCOMPAGT [16], a database system which allows the successful data handling and quality assurance of mitochondrial DNA (mtDNA) genotypes for medical genetics, population genetics and forensics. eCOMPAGT imports mtDNA profiles generated with Sequencher or SeqScape, compares double evaluations of profiles for validation, stores profiles in a relational database system and allows different export formats for disease-association studies, population genetics, forensic databases and for the construction of phylogenetic networks
Export to various software programs and population databases In forensic genetics it is necessary to determine the rarity of a given mtDNA profile
