ABSTRACT
MitBASE is a comprehensive and integrated mitochondrial genome database funded within the EU BIOTECH PROGRAM. It is a project for the development and implementation of an integrated and comprehensive database of mitochondrial data which will collect all available information from different organisms and from intraspecies variants and mutants. The present paper describes the structure of the Human dataset in mitBASE where human molecular data are distinguished from clinical and pathological data.

The present paper describes the improvements in MmtDB, a specialised database designed to collect Metazoa mitochondrial DNA variants. Priority in the data collection has been given to Metazoa for which a large amount of variants is available, e.g., for humans. Starting from the sequences available in the Nucleotide Sequence Databases, the redundant sequences have been removed and new sequences from other sources have been added. Value-added information is associated to each variant sequence, e.g., analysed region, experimental method, tissue and cell lines, population data, sex, age, family code and information about the variation events (nucleotide position, involved gene, restriction site gain or loss). Cross-references are introduced to the EMBL Data Library, as well as an internal cross-referencing among MmtDB entries according to tissual, heteroplasmic, familiar and aplotypical correlation. Furthermore MmtDB has a new section, AMmtDB: Aligned Metazoan mitochondrial biosequences. MmtDB can be accessed through the World Wide Web at URL http://WWW.ba.cnr.it/[symbol: see text]areamt08/MmtDBWWW.htm

The present paper describes the structure of MmtDB-a specialized database designed to collect Metazoa mitochondrial DNA variants. Priority in the data collection is given to the Metazoa species for which a large amount of variants is available, as it is the case for human variants. Starting from the sequences available in the Nucleotide Sequence Databases, the redundant sequences are removed and new sequences from other sources are added. Value-added information are associated to each variant sequence, e.g. analysed region, experimental method, tissue and cell lines, population data, sex, age, family code and information about the variation events (nucleotide position, involved gene, restriction site's gain or loss). Cross-references are introduced to the EMBL Data Library, as well as an internal cross-referencing among MmtDB entries according to their tissual, heteroplasmic, familiar and aplotypical correlation. MmtDB can be accessed through the World Wide Web at URL [see text].
