Myoclonic epilepsy myopathy sensory ataxia, commonly called MEMSA, is part of a group of conditions called the POLG-related disorders. The conditions in this group feature a range of similar signs and symptoms involving muscle-, nerve-, and brain-related functions. The signs and symptoms of MEMSA typically appear during young adulthood.
Deleterious variants in the POLG gene, which encodes an enzyme required for replication and repair of the mtDNA, result in several clinically defined syndromes, including Alpers-Huttenlocher syndrome (AHS; also known as Alpers syndrome), childhood myocerebrohepatopathy spectrum (MCHS), myoclonic epilepsy myopathy sensory ataxia (MEMSA), ataxia neuropathy spectrum (ANS), autosomal recessive Myoclonic Epilepsy, Myopathy, Sensory Ataxia (MEMSA) Mitochondrial encephalomyopathy lactic acidosis, and stroke-like episodes (MELAS) Myoclonic Epilepsy with Ragged-Red Fibers (MERRF) Mitochondrial Recessive Ataxia Syndrome (MIRAS) Cerebellar ataxia infantile with progressive external ophthalmoplegia Sensory ataxic neuropathy, dysarthria, and ophthalmoparesis Myoclonic epilepsy myopathy sensory ataxia Progressive sclerosing poliodystrophy Autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions 1 not provided POLG-Related Spectrum Disorders Myoclonic Epilepsy Myopathy Sensory Ataxia (MEMSA) MEMSA has the dominant features of epilepsy, myopathy, and ataxia, but without ophthalmo-plegia. A subclinical sensory polyneuropathy leading to ataxia is usually the first sign of the disease. Usually seen later in the disease course, myoclonicseizuresareoftenfocal,frequentlyin- Myoclonic epilepsy with red ragged fibres (MERRF) is a rare mitochondrial disorder presenting with progressive myoclonus, epilepsy, and cognitive decline. Here, the authors present a case of a 29-year-old lady presenting with myoclonus and describe the subsequent investigations that led to a diagnosis of MERRF. In addition, we examine her cognitive decline over a 9-year period, demonstrating a Brain (1996), 119, 997-1010 Mitochondrial cytopathy presenting as hereditary sensory neuropathy with progressive external ophthalmoplegia, ataxia and fatal myoclonic Eight patients were examined: 7 with SANDO (Sensory Ataxic Neuropathy, Dysarthria, Ophthalmoparesis) syndrome, and 1 with MEMSA (Myoclonic Epilepsy Myopathy Sensory Ataxia) syndrome; median age was 32.5 years.
The six leading disorders caused by POLG mutations are Alpers-Huttenlocher syndrome, which is one of the most severe phenotypes; childhood myocerebrohepatopathy spectrum, which presents within the first 3 years of life; myoclonic epilepsy myopathy sensory ataxia; ataxia neuropathy spectrum; autosomal recessive progressive external ophthalmoplegia; and autosomal dominant progressive external ophthalmoplegia.

Myoclonic Epilepsy with Ragged-Red Fibers (MERRF) syndrome was first described in 1980 as a multisystemic encephalomyopathy [].MERRF syndrome is due to a point mutation in mitochondrial DNA (most often m.A8344G) leading to a defect on the MT-TK gene encoding a lysine transfer RNA [].MERRF is characterized by myoclonus, epilepsy, ataxia and patients may present myopathy… The authors describe a family (mother, son and two daughters) with mitochondrial myopathy.
chondrial myopathy. The mother was asymptomatic. Two daughters had lactic acidosis and myoclonic epilepsy, mild dementia, ataxia, weakness and sensory neuropathy. The son suffered one acute hemiplegic episode due to an ischemic infarct in the right temporal region. All the patients studied had hypertension.
