A human mitochondrial genome database

A compendium of polymorphisms and mutations in human mitochondrial DNA
MITOMAP reports published data on human mitochondrial DNA variation. If you would like to add a paper and its data into MITOMAP, please email a pdf to We appreciate your help.
Science Cover

2021 Update #2: On July 15, 2021 we added 797 new full-length (FL) and 107 new control region (CR) GenBank sequences to our database. This brings our total number of FL sequences to 52,633 and the number of CR sequences to 74,970. Our SNVs now total 19,644. We update our GenBank sequences every 4-6 months. Hand curation of variants and references continues weekly. See the GenBank Frequency Info page for details about our current sequence sets.

2021 Special Update [March 23, 2021]: We are pleased to announce that we have updated Allele Search to give you direct access to more variant data. New features include allele frequencies from gnomAD v3.1 and the Helix database, pathogenicity consensus scores for coding variants from MitImpact’s APOGEE tool, and conservation percentages.

PICK We have starred our user Favorites for seeking information on specific variants and for understanding the contents of our database.
