Fig. 3: Different mutational spectra between shared and private mutations.

a Number of shared mutations (blue), primary private mutations (PP, purple), and metastatic private mutations (MP, pink) in each patient. b Heteroplasmy levels among the three groups. Bar represents median values. c Base substitution spectrum among the three groups. Mutations are denoted based on pyrimidine base. H, H-strand; L, L-strand. d Mutation proportions in mtDNA D-loop and coding regions among the three groups. e Mutation density in mtDNA D-loop and coding regions among the three groups.
