Figure 1. Number of somatic single nucleotide variants (SNVs) distributed over the gene, control and non-protein coding regions of the mitochondrial genome, defined as (A) absolute number of SNVs and (B) number of SNVs scaled by region length (SNVs per 1000 bases). Genes/regions are represented in order of appearance on the mitochondrial genome, with genes colored by functional prediction of SNV.
