Summaries for Progressive External Ophthalmoplegia with Mitochondrial Dna...

OMIM : 57 Autosomal recessive progressive external ophthalmoplegia with mitochondrial DNA deletions-4 (PEOB4) is an autosomal recessive disorder characterized by adult onset of eye muscle weakness and proximal limb muscle weakness associated with deletions of mtDNA on skeletal muscle biopsy, which results from defective mtDNA replication in post-mitotic muscle tissue. Additional features are more variable (summary by Ronchi et al., 2012). For a discussion of genetic heterogeneity of autosomal recessive PEO, see PEOB1 (258450). (617070)

MalaCards based summary : Progressive External Ophthalmoplegia with Mitochondrial Dna Deletions, Autosomal Recessive 4, is also known as progressive external ophthalmoplegia, autosomal recessive 4. An important gene associated with Progressive External Ophthalmoplegia with Mitochondrial Dna Deletions, Autosomal Recessive 4 is DGUOK (Deoxyguanosine Kinase). Affiliated tissues include eye, skeletal muscle and bone, and related phenotypes are ptosis and dysphonia

UniProtKB/Swiss-Prot : 75 Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal recessive 4: A form of progressive external ophthalmoplegia, a mitochondrial myopathy characterized by progressive paralysis of the levator palpebrae, orbicularis oculi, and extraocular muscles. PEOB4 patients manifest clinically variable features including mitochondrial myopathy with or without progressive external ophthalmoplegia, recurrent rhabdomyolysis, and adult-onset lower motor neuron syndrome with mild cognitive impairment.
