Additional Information:

Description: (OMIM) Progressive external ophthalmoplegia is characterized by multiple mitochondrial DNA deletions in skeletal muscle. The most common clinical features include adult onset of weakness of the external eye muscles and exercise intolerance. Additional symptoms are variable, and may include ...
Clinical Description OMIM Lundberg (1962, 1966, 1974) described a large Swedish kindred in which progressive external ophthalmoplegia was associated with hypogonadism. Melberg et al. (1996) provided follow-up. Hypogonadism included delayed sexual maturation, primary amenorrhea, early menopause, and testicular atrophy. Cataracts, cerebellar ...
Genotype-Phenotype Correlations OMIM Lamantea et al. (2002) identified POLG mutations in 10 adPEO families and noted that the clinical features of these patients were often more severe and complex than those associated with ANT1 or C10ORF2 mutations. In particular, patients with ...
Molecular genetics OMIM Hirano and DiMauro (2001) reviewed the molecular genetics of progressive external ophthalmoplegia and classified the specific disease type according to mutation in the autosomal ANT1, C10ORF2, and POLG genes as well as in multiple mitochondrial genes.
