Muscle pathological changes of the patients. ac are ATPase staining at pH 10.6, 10.7 and 10.6 of patient II-6 (family A), II-2 (family B) and III-1 (family C) respectively, showing type 2 fibers predominance. c also shows fiber type grouping. d is H&E staining of patient III-1 (family C) showing increased fiber size variation, necrotic and degenerated fibers. e is SDH staining of patient III-1 (family C) showing subsarcolemmal mitochondria accumulation. F is NADH-TR staining of patient II-2 (family D) showing multiple cores. All bar = 200 μm. NADH-TR, nicotinamide adenine dinucleotide tetrazolium reductase; SDH, succinate dehydrogenase
