La·fo·ra bod·y dis·ease

(lah-fō'rah), [MIM*254780]
a form of progressive myoclonus epilepsy beginning from age 6-19; characterized by generalized tonic-clonic seizures, resting and action myoclonus, ataxia, dementia, and classic EEG findings, including polyspike and wave discharges; basophilic cytoplasmic inclusion bodies present in portions of the brain, the liver, and skin, as well as the duct cells of the sweat glands. Death usually occurs within 10 years of onset; autosomal recessive inheritance, caused by mutation in the progressive myoclonic epilepsy 2 gene (EPM2A) on chromosome 6q.
Synonym(s): Lafora disease
