Progressive External Ophthalmoplegia with Mitochondrial Dna Deletions, Autosomal Dominant 1, also known as peoa1, is related to progressive external ophthalmoplegia with mitochondrial dna deletions, autosomal recessive 1 and chronic progressive external ophthalmoplegia, and has symptoms including cerebellar ataxia, seizures and muscle weakness. An important gene associated with Progressive External Ophthalmoplegia with Mitochondrial Dna Deletions, Autosomal Dominant 1 is POLG (DNA Polymerase Gamma, Catalytic Subunit). The drugs 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid and Protective Agents have been mentioned in the context of this disorder. Affiliated tissues include skeletal muscle and eye, and related phenotypes are parkinsonism and bradykinesia
