Classification tree of the proband's complete mtDNA sequence. Nucleotide position numbers are relative to the RSRS and rCRS. The mutations 309.1C(C), 315.1C, AC indels at 515–522, 16182C, 16183C, 16193.1C(C), and 16519 were not considered for phylogenetic reconstruction and are, therefore, excluded from the tree. The GeneBank Accession number for C19 and CN19 is GU392103.1 and GU392102.1, respectively.
