Myoclonic Epilepsy Associated with Ragged-Red Fibers, also known as merrf syndrome, is related to mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes and mitochondrial myopathy. An important gene associated with Myoclonic Epilepsy Associated with Ragged-Red Fibers is MT-TL1 (Mitochondrially Encoded TRNA-Leu (UUA/G) 1), and among its related pathways/superpathways are Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins. and Complex I biogenesis. Affiliated tissues include eye and heart, and related phenotypes are ataxia and sensorineural hearing impairment
