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...

Mitochondrial (mt) neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive disease associated with depletion, deletions, and point mutations of mtDNA. Patients lack a functional thymidine phosphorylase and their plasma contains high concentrations of thymidine and deoxyuridine; elevation of the corresponding triphosphates probably impairs normal mtDNA replication and repair. T...

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare, autosomal-recessive mitochondrial disorder caused by TYMP mutations presenting with a multisystemic, often lethal syndrome of progressive leukoencephalopathy, ophthalmoparesis, demyelinating neuropathy, cachexia and gastrointestinal dysmotility. Hemodialysis (HMD) has been suggested as a treatment to reduce accumulation of...

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a devastating autosomal recessive disorder due to mutations in TYMP, which cause loss of function of thymidine phosphorylase (TP), nucleoside accumulation in plasma and tissues and mitochondrial dysfunction. The clinical picture includes progressive gastrointestinal dysmotility, cachexia, ptosis and ophthalmoparesis, peripheral ne...

m.3291T > C mutation in the MT-TL1 gene has been infrequently encountered in association with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS), however remains poorly characterized from a clinical perspective. In the following report we describe in detail the phenotypic features, long term follow up (> 7 years) and management in a Caucasian family with ME...
