Cerebellar ataxia was the first symptom in all patients. Conventional brain MR imaging showed atrophy of the superior cerebellar peduncles and the cerebellum in all patients and brain stem atrophy in 2 patients. In diffusion tensor analysis, fractional anisotropy of MERRF (Myoclonic Epilepsy with Ragged Red Fibers) syndrome is a mitochondrial encephalomyopathy characterized by myoclonic seizures. ORPHA:551 Classification level: Disorder About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Myoclonic Epilepsy with Ragged Red Fibers Involuntary muscle twitches, generalized epilepsy, and cerebellar ataxia — these symptoms are typically indicative of a mitochondrial myopathy. Yet with the different types of mitochondrial myopathies, it may be difficult 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.

Rubio†‡, Juan D. Alfonzo*†‡, Kurt Fredrick*†‡, Selective vulnerability of subpopulations of neurons is a striking feature of neurodegeneration. Mitochondrially transmitted diseases are no exception. In this study CNS tissues from a patient with myoclonus epilepsy and ragged red fibers (MERRF) syndrome, which results from an A to G transition of nucleotide (nt) 8344 in the mitochondrial tRNALys gene, were examined for the proportion of Myoclonic epilepsy with ragged red fibers (MERRF) is characterized by myoclonus, seizures, and ataxia; myopathy, hearing loss, and vision loss can also occur. Genetic tests are available for these Epilepsy affects the central nervous systems and allows abnormal activity within the brain. This disease affects men and women and does not seem to be more prevalent in any particular race. While some people require treatment throughout the Myoclonic epilepsy with ragged-red fibers (MERRF) is a disorder that affects many parts of the body, particularly the muscles and nervous system.
Historical note and terminology In 1921 Ramsay Hunt described six patients with a disorder resembling Friedreich ataxia characterized by ataxia, myoclonus, and epilepsy, which he called "dyssynergia cerebellaris myoclonica" ( Hunt 1921 ). SUMMARY: We report 3 patients with myoclonic epilepsy with ragged-red fibers (MERRF) diagnosed by mitochondrial A8344G mutation. Cerebellar ataxia was the first symptom in all patients.

The disease is maternally inherited as is the mtDNA. Myoclonic epilepsy with ragged-red fibers (MERRF) is a disorder that affects many parts of the body, particularly muscles and the 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.
