A new mtDNA mutation associated with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS).
In 3 of 40 MELAS patients, a new common mutation, a T-to-C transition at nucleotide position 3271 in the mitochondrial tRNA(Leu(UUR] gene was recognized and was very near to the most common mutation site at 3243. With a simple detection method using polymerase chain reaction with a mismatch primer, none of 46 patients with other mitochondrial diseases and 50 controls had this mutation.

متن کاملHuman mitochondrial leucyl-tRNA synthetase corrects mitochondrial dysfunctions due to the tRNALeu(UUR) A3243G mutation, associated with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like symptoms and diabetes.
Mutations in mitochondrial tRNA genes are associated with a wide spectrum of human diseases. In particular, the tRNA(Leu(UUR)) A3243G mutation causes mitochondrial encephalomyopathy, lactic acidosis, and stroke-like symptoms (MELAS) and 2% of cases of type 2 diabetes. The primary defect in this mutation was an inefficient aminoacylation of the tRNA(Leu(UUR)). In the present study, we have inves...

A case of 25-year-old woman with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) was reported. She had short stature, episodic vomiting with headache, several episodes with homonymous hemianopsia, progressive intellectual decline, generalized convulsion, muscular atrophy, sensory disturbance on the left side of the body, and primary amenorrhea. Lactate, pyruvat...
متن کاملSerial diffusion imaging in a case of mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes.
BACKGROUND AND PURPOSE Most diffusion MRI studies of mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episode stroke-like lesions report high- or normal-apparent diffusion coefficient, and this has been used to differentiate stroke-like lesion from ischemic stroke. There are, however, 3 recent reports of restricted diffusion in the acute phase of the stroke-like lesions. The pu...
