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].
