Fig. 1From: Mutation m.15923A>G in the MT-TT gene causes mild myopathy – case report of an adult-onset phenotypeMutation m.15923A > G is situated in a conservative position and causes typical mitochondria myopathy. a Sequence chromatograms showing variable heteroplasmy. P, patient; COX+, biochemically normal fibers; COX−, cytochrome c-oxidase negative fibers. b Histology stainings. Left panel: Hematoxylin & eosin staining showing ragged red fibers. Right panel: Cytochrome c-oxidase staining showing COX-negative (blue) fibers. Arrows denote biochemically abnormal fibers. c Clustal Omega [15] alingnment for multiple sequences showing complete conservation between speciesBack to article page
