Use PolyPhen and SIFT to predict mtDNA mutations and variants. The dark shaded areas are proportions of mutations or variants predicted to be deleterious; the light shaded areas are variants predicted to be benign. LHON, Leber hereditary optic neuropathy; mtDNA, mitochondrial DNA; PolyPhen, polymorphism phenotyping; SIFT, sorting intolerant from tolerant.
