An important gene associated with Progressive External Ophthalmoplegia with Mitochondrial Dna Deletions, Autosomal Dominant 3 is TWNK (Twinkle MtDNA Helicase), and among its related pathways/superpathways is Primary ovarian insufficiency. 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 seizure and dysarthria
