Summaries for Progressive External Ophthalmoplegia with Mitochondrial Dna...

UniProtKB/Swiss-Prot : 75 Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant, 4: A disorder characterized by progressive weakness of ocular muscles and levator muscle of the upper eyelid. In a minority of cases, it is associated with skeletal myopathy, which predominantly involves axial or proximal muscles and which causes abnormal fatigability and even permanent muscle weakness. Ragged-red fibers and atrophy are found on muscle biopsy. A large proportion of chronic ophthalmoplegias are associated with other symptoms, leading to a multisystemic pattern of this disease. Additional symptoms are variable, and may include cataracts, hearing loss, sensory axonal neuropathy, ataxia, depression, hypogonadism, and parkinsonism.

MalaCards based summary : Progressive External Ophthalmoplegia with Mitochondrial Dna Deletions, Autosomal Dominant 4, also known as progressive external ophthalmoplegia with mitochondrial dna deletions, autosomal dominant, 4, is related to chronic progressive external ophthalmoplegia and kearns-sayre syndrome, and has symptoms including seizures, muscle weakness and myalgia. An important gene associated with Progressive External Ophthalmoplegia with Mitochondrial Dna Deletions, Autosomal Dominant 4 is POLG2 (DNA Polymerase Gamma 2, Accessory Subunit). Affiliated tissues include liver, eye and skeletal muscle, and related phenotypes are ptosis and seizures

OMIM : 57 Progressive external ophthalmoplegia-4 is an autosomal dominant form of mitochondrial disease that variably affects skeletal muscle, the nervous system, the liver, and the gastrointestinal tract. Age at onset ranges from infancy to adulthood. The phenotype ranges from relatively mild, with adult-onset skeletal muscle weakness and weakness of the external eye muscles, to severe, with a multisystem disorder characterized by delayed psychomotor development, lactic acidosis, constipation, and liver involvement (summary by Young et al., 2011). For a general phenotypic description and a discussion of genetic heterogeneity of autosomal dominant progressive external ophthalmoplegia, see PEOA1 (157640). (610131)
