  Lafora disease - Wikipedia, the free encyclopedia
Lafora disease is a hereditary disease characterised by the presence of inclusion bodies, known as Lafora bodies, within the cells of neurons, heart, liver, muscle, and skin.
Diagnosis is based on the demonstration of Lafora bodies within the sweat cells of the skin by an axillary skin biopsy examination.
Genetic studies have recently disclosed that a gene (named as EPM2A) encoding the protein laforin is strongly associated with the disease.

Lafora disease (LD) is a rare genetic disorder that occurs in children or adolescents, resulting in progressive decline of mental function.
Lafora disease is a genetic disorder with autosomal recessive inheritance, meaning that a child can only get the disease if both of his/her parents are carriers for the mutant gene.
Lafora disease is diagnosed based on the results of a biopsy of an individual’s skin, liver, muscle, or brain.

 [No title]
Summary: Lafora body disease is an autosomal recessive stimulus-sensitive progressive myoclonic epilepsy with onset in the late childhood or adolescence.
Pathologically it is associated with neuronal inclusions (Lafora bodies) in the cerebral and cerebellar cortex and in brain stem nuclei.
Although the storage material in Lafora disease is histochemically, ultrastructurally, and biochemically similar to polysaccharide that accumulates in branching enzyme activity (type IV glycogenosis), branching enzyme activity was normal in brain and muscle from one patient.

We are interested in determining the molecular mechanisms of inherited neurological disorders by identifying and characterizing disease genes using molecular genetics approaches.
In fact, every gene, when mutated, is a potential disease gene, and we end up with the new concept of 'reverse medicine'; i.e., deriving new diseases or pathogenic pathways from the knowledge of the structure and function of every gene.
Multi-generation families affected with neurological disease are to be used for whole genome screens to identify new susceptibility loci or candidate gene loci.

 UCSD research reveals mechanism involved with type of fatal epilepsy
Researchers at University of California, San Diego (UCSD) have found that Lafora disease, an inherited form of epilepsy that results in death by the age of 30, can be caused by mutations in a gene that regulates the concentration of the protein laforin.
Lafora disease is characterized by normal development for the first decade of life, followed by an initial seizure in the second decade, progressively worsening seizures, early dementia, and death within 10 years of onset.
A puzzling aspect of the disease is the accumulation of starch-/glycogen-like granules in most tissues of Lafora disease patients.

 Encyclopedia: Lafora disease
A genetic disorder, or genetic disease is a disease caused, at least in part, by the genes of the person with the disease.
Although seizure and myoclonus can be controlled for a long period by using antiepileptic drugs, patients are usually lost within one or two decades due to the devastating effects of dementia and ataxia.
Diagnosis (from the Greek words dia = by and gnosis = knowledge) is the process of identifying a disease by its signs, symptoms and results of various diagnostic procedures.

 Lafora disease   (Site not responding. Last check: 2007-11-06)
The patients develop the first symptoms mainly during adolescence and major problems are seizure, drop attacks, myoclonus[?], ataxia and most importantly a very quickly developing, progressive and severe dementia.
Neither the origin of these inclusions nor the exact mechanisms how they cause the disease are known.
