A Novel Mutation of Mitochondrial T14709C Causes Myoclonic Epilepsy with Ragged Red Fibers Syndrome in a Chinese Patient Myoclonic epilepsy with ragged-red fibers (MERRF) is a disorder that affects many parts of the body, particularly the muscles and nervous system. In most cases, the signs and symptoms of this disorder appear during childhood or adolescence. The features of MERRF vary widely among affected individuals, even among members of the same family. [Source] Myoclonic epilepsy with ragged red fibres or MERRF syndrome is a genetic disease which affects the patient's mitochondria. It's name comes from the appearance of damaged mitochondria which align themselves to muscle fibres and appear as red fibres when stained and put under a microscope.

Myoclonus epilepsy with ragged-red fibers (MERRFs), an inherited mitochondrial disorder, has characteristic morphological changes of ragged-red fibers (RRFs) in muscle biopsy, in the absence of which mitochondrial etiology is usually not considered in patients with phenotypes suggestive of MERRF. In these circumstances, MERRF can only be diagnosed using genetic analyses. The symptoms B. Myoclonic Epilepsy and Ragged Red Fibers.

Abstract We report myoclonic epilepsy with ragged-red fibers (MERRF) syndrome in a Chinese family with confirmed mitochondrial DNA point mutation. Six members of the family including the grandmother, two siblings, and three grandchildren were affected. The acronym, MERRF, or myoclonus epilepsy and ragged red fiber disease, represents one of the early mitochondrial syndromes, whose molecular genetic basis was first established in 1990 by Shoffner and coworkers.
