متن کاملSLC25A4 and C10ORF2 Mutations in Autosomal Dominant Progressive External Ophthalmoplegia
BACKGROUND AND PURPOSE Progressive external ophthalmoplegia (PEO) with Mendelian inheritance is a heterogeneous group of diseases associated with multiple deletions of mitochondrial DNA (mtDNA), which results from the disturbed replication and maintenance of mtDNA secondary to the mutations of nuclear genes including POLG, SLC25A4, C10ORF2, POLG2, OPA1, and RRM2B. The aim of this study was to i...
متن کاملChronic progressive external ophthalmoplegia with inflammatory myopathy.
Chronic progressive external ophthalmoplegia is one of mitochondrial disorders, characterized by ptosis, limitation of eye movement, variably severe bulbar muscle weakness and proximal limb weakness. Chronic progressive external ophthalmoplegia complicated with acquired disease is extremely rare. We report a 44 years old male patient with more than 20 years of chronic progressive bilateral ptos...
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 کاملConcerted action of two novel tRNA mtDNA point mutations in chronic progressive external ophthalmoplegia.
CPEO (chronic progressive external ophthalmoplegia) is a common mitochondrial disease phenotype in adults which is due to mtDNA (mitochondrial DNA) point mutations in a subset of patients. Attributing pathogenicity to novel tRNA mtDNA mutations still poses a challenge, particularly when several mtDNA sequence variants are present. In the present study we report a CPEO patient for whom sequencin...
