Mitochondrial ND5 gene variation associated with encephalomyopathy and mitochondrial ATP consumption.
Mitochondrial encephalomyopathy and lactic acidosis with strokelike episodes (MELAS) is a severe young onset stroke disorder without effective treatment. We have identified a MELAS patient harboring a 13528A-->G mitochondrial DNA (mtDNA) mutation in the Complex I ND5 gene. This mutation was homoplasmic in mtDNA from patient muscle and nearly homoplasmic (99.9%) in blood. Fibroblasts from the pa...
متن کاملND5 is a hot-spot for multiple atypical mitochondrial DNA deletions in mitochondrial neurogastrointestinal encephalomyopathy.
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive multisystem disorder associated with depletion, multiple deletions and site-specific point mutations of mitochondrial DNA (mtDNA). MNGIE is caused by loss-of-function mutations in the gene encoding thymidine phosphorylase (TP; endothelial cell growth factor 1). Deficiency of TP leads to dramatically elevated...

mitochondrial neurogastrointestinal encephalo-myopathy (mngie) is a rare autosomal recessive disease caused by thymidine phosphorylase (tp) gene mutation. here we report a patient with mngie in whom sensorimotor polyneuropathy was the first presenting symptom and had a fluctuating course. this 26-year-old female patient developed acute-onset demyelinating polyneuropathy from the age of 6 with t...
متن کاملMR demonstration of leukoencephalopathy associated with mitochondrial encephalomyopathy: case report.
The mitochondrial encephalomyopathies are a heterogeneous group of disorders characterized by mitochondrial dysfunction that produce multisystem symptoms. This disorder affects both the central and peripheral nervous systems, skeletal muscles, heart, endocrine glands, gastrointestinal tract, hematopoietic system, and kidneys (Table 1) [1]. Patients with mitochondrial encephalomyopathy can be di...
متن کاملBiochemical studies in mitochondrial encephalomyopathy.
The alpha-keto acid dehydrogenase complex and its component enzymes, lactate dehydrogenase, pyruvate carboxylase, cytochrome c oxidase, succinate-cytochrome c reductase, NADH-cytochrome c reductase, and the concentration of cytochromes and enzymes of beta-oxidation in muscle from a patient with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes were studied and no ...
