mitochondrial neurogastrointestinal encephalomyopathy (mngie)
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 کاملMitochondrial neurogastrointestinal encephalomyopathy (MNGIE): biochemical features and therapeutic approaches.
Over the last 15 years, important research has expanded our knowledge of the clinical, molecular genetic, and biochemical features of mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). The characterization of mitochondrial involvement in this disorder and the seminal determination of its genetic cause, have opened new possibilities for more detailed and deeper studies on the pathome...
متن کاملMitochondrial deoxynucleotide pools in quiescent fibroblasts: a possible model for mitochondrial neurogastrointestinal encephalomyopathy (MNGIE).
Mitochondrial (mt) DNA depletion syndromes can arise from genetic deficiencies for enzymes of dNTP metabolism, operating either inside or outside mitochondria. MNGIE is caused by the deficiency of cytosolic thymidine phosphorylase that degrades thymidine and deoxyuridine. The extracellular fluid of the patients contains 10-20 microM deoxynucleosides leading to changes in dTTP that may disturb m...
متن کاملLimited dCTP Availability Accounts for Mitochondrial DNA Depletion in Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE)
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a severe human disease caused by mutations in TYMP, the gene encoding thymidine phosphorylase (TP). It belongs to a broader group of disorders characterized by a pronounced reduction in mitochondrial DNA (mtDNA) copy number in one or more tissues. In most cases, these disorders are caused by mutations in genes involved in deoxyrib...
