Myoclonic epilepsy with ragged-red fibers (MERRF) Mutations in the MT-TF gene have been associated with myoclonic epilepsy with ragged-red fibers (MERRF). Myoclonic epilepsy with ragged-red fibers (MERRF) is a disorder that affects many parts of the body, particularly the muscles and nervous system.

For detailed clinical features, see MOLECULAR GENETICS. Inheritance. Rosing et al. (1985) described an extensive family in which many members showed this combination of abnormalities which goes by the acronymic designation MERRF syndrome.

B. Myoclonic Epilepsy and Ragged Red Fibers. Myoclonic epilepsy and ragged red fibers (MERRF) is caused in 80% of cases by an A-to-G mutation in the tRNA Lys gene (MTTK) at position nt-8344 of the mtDNA. Two other mutations, 8356T-to-C and 8363G-to-A, have been found in the same gene but occur infrequently.
