DNA isolated from muscle biopsy showed A8344G mutation of mitochondrial DNA (tRNA [Lys] gene), associated with 80% of patients with myoclonic epilepsy with ragged-red fibers (MERRF). MERRF is a rare mitochondrial disorder with variable onset and clinical presentation.

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

Myoclonic epilepsy with ragged-red fibers is a maternally inherited disease that is characterized by myoclonic epilepsy, cerebellar ataxia and progressive muscular weakness. The present study reports the case of a 25-year-old male who presented with paroxysmal left upper limb tics and weakness for two years. 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.

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. 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

Myoclonic Epilepsy with Ragged Red Fibers (MERRF) is a multisystem mitochondrial disease.1 MERRF typically presents with myoclonus (brief, involuntary twitching of a muscle or a group of muscles), followed by generalized epilepsy, ataxia (lack of coordination of muscle movements), weakness, and dementia.1 Ragged red fibers Myoclonic epilepsy with ragged-red fibers Also known as: Fukuhara Disease, MERRF, MERRF syndrome, myoclonic epilepsy associated with ragged-red fibers, myoencephalopathy ragged-red fiber disease Myoclonic epilepsy with red-ragged fibers (MERRF) is a rare multisystem mitochondrial disease with predominant progressive myoclonus. It is common in children and young adolescents. This activity reviews the evaluation and management of MERRF and highlights the role of interprofessional team members in collaborating to provide well-coordinated care and enhance patient outcomes. Myoclonic epilepsy with ragged‐red fibers (MERRF) is a maternally inherited disorder of oxidative phos‐phorylation due to specific point mutations within the mitochondrial tRNA Lvs gene. Mitochondrial dysfunction in the central nervous system (CNS) of patients with MERRF accounts for the neurological manifestations of the disease.

The present study reports the case of a 25‑year‑old male who presented with paroxysmal left upper limb tics and weakness for two years. 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.
