MITOMAP: mtDNA Coding Region & RNA Sequence Variants

Last Edited: Nov 03, 2025

The GB frequency data is derived from 62516 GenBank sequences with size greater than 15.4kbp and 81074 Control Region sequences with size 0.4-1.6kbp. These sequences have been pre-loaded into Mitomaster and represent almost all haplogroups known to date. We will be updating and refining this set of sequences on a regular basis. As a caveat, please note that GenBank sequences may not be of equal quality (Yao, et al, 2009), that some of these sequences are from individuals with past, current or future disease, and that this portion of our data set has not been hand-curated by Mitomap.
