متن کاملMitochondrial myopathy with chronic progressive external ophthalmoplegia.
Introduction Mitochondrial diseases are a diverse group with multisystem involvement caused by structural, biochemical or genetic derangement of mitochondria. Cerebral neurones and myocytes which require a high yield of energy are particularly vulnerable to mitochondrial dysfunction and neuromuscular manifestations are common in mitochodrial disorders. We report two cases of mitochondrial myopa...
متن کاملmitochondrial 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 کاملHuman mitochondrial DNA replication machinery and disease.
The human mitochondrial genome is replicated by DNA polymerase γ in concert with key components of the mitochondrial DNA (mtDNA) replication machinery. Defects in mtDNA replication or nucleotide metabolism cause deletions, point mutations, or depletion of mtDNA. The resulting loss of cellular respiration ultimately induces mitochondrial genetic diseases, including mtDNA depletion syndromes (MDS...
