* Footnotes:

Full Length (FL) sequences are now classified into three subsets: aDNA for ancient DNA, CancerCL for cancer, tumor, other abnormal tissues, or cell line studies (include cybrids), and Main for the rest.

The current sequence counts are from two sets of human mitochondrial sequences collected from GenBank on Feb 03, 2026. These sets consist of:
