Summaries for Mitochondrial Dna Depletion Syndrome 11

OMIM® : 57 Mitochondrial DNA depletion syndrome-11 is an autosomal recessive mitochondrial disorder characterized by onset in childhood or adulthood of progressive external ophthalmoplegia (PEO), muscle weakness and atrophy, exercise intolerance, and respiratory insufficiency due to muscle weakness. More variable features include spinal deformity, emaciation, and cardiac abnormalities. Skeletal muscle biopsies show deletion and depletion of mitochondrial DNA (mtDNA) with variable defects in respiratory chain enzyme activities (summary by Kornblum et al., 2013). For a discussion of genetic heterogeneity of autosomal recessive mtDNA depletion syndromes, see MTDPS1 (603041). (615084) (Updated 05-Mar-2021)

MalaCards based summary : Mitochondrial Dna Depletion Syndrome 11, also known as progressive external ophthalmoplegia-myopathy-emaciation syndrome, is related to mitochondrial dna depletion syndrome and mitochondrial dna depletion syndrome 2, and has symptoms including dyspnea and facial paresis. An important gene associated with Mitochondrial Dna Depletion Syndrome 11 is MGME1 (Mitochondrial Genome Maintenance Exonuclease 1), and among its related pathways/superpathways is Mitochondrial Gene Expression. Affiliated tissues include eye and skeletal muscle, and related phenotypes are progressive external ophthalmoplegia and ptosis

Disease Ontology : 12 A mitochondrial DNA depletion syndrome that is characterized by onset in childhood or adulthood of progressive external ophthalmoplegia (PEO), muscle weakness and atrophy, exercise intolerance, and respiratory insufficiency due to muscle weakness, and has material basis in autosomal recessive inheritance of homozygous mutation in the mitochondrial genome maintenance exonuclease 1 gene on chromosome 20p11.

UniProtKB/Swiss-Prot : 73 Mitochondrial DNA depletion syndrome 11: An autosomal recessive mitochondrial disorder characterized by onset in childhood or adulthood of progressive external ophthalmoplegia, muscle weakness and atrophy, exercise intolerance, and respiratory insufficiency due to muscle weakness. More variable features include spinal deformity, emaciation, and cardiac abnormalities. Skeletal muscle biopsies show deletion and depletion of mitochondrial DNA (mtDNA) with variable defects in respiratory chain enzyme activities.
