چکیده انگلیسی
We describe a 7-year-old girl who presented with loss of appetite, weakness and excercise intolerance. Enzyme investigation of the respiratory chain in muscle tissue revealed a combined complex I, III and IV deficiency. A novel heteroplasmic G → A exchange at nucleotide position 14739 was found in the MTTE gene of the tRNA glutamic acid. The mutation load in muscle was 72%, urine sediment 38%, blood 31% and fibroblasts 29% and it correlated with COX-negative fibres. Our patient presented with a predominantly myopathic phenotype. The G14739A mutation is the third reported in the mitochondrial tRNA glutamic acid gene, and it occurred in a sporadic case.
