Summaries for Epilepsy, Idiopathic Generalized 11

UniProtKB/Swiss-Prot : 71 Epilepsy, idiopathic generalized 11: A disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. Juvenile absence epilepsy 2: A subtype of idiopathic generalized epilepsy characterized by onset occurring around puberty, absence seizures, generalized tonic-clonic seizures (GTCS), GTCS on awakening, and myoclonic seizures. Juvenile myoclonic epilepsy 8: A subtype of idiopathic generalized epilepsy. Patients have afebrile seizures only, with onset in adolescence (rather than in childhood) and myoclonic jerks which usually occur after awakening and are triggered by sleep deprivation and fatigue.

MalaCards based summary : Epilepsy, Idiopathic Generalized 11, is also known as epilepsy, juvenile absence 2, and has symptoms including absence seizures, generalized myoclonic seizures and generalized tonic-clonic seizures on awakening. An important gene associated with Epilepsy, Idiopathic Generalized 11 is CLCN2 (Chloride Voltage-Gated Channel 2). The drugs Neuroserpin and Astragalus have been mentioned in the context of this disorder. Affiliated tissues include brain.

OMIM : 54
Both juvenile myoclonic epilepsy and juvenile absence epilepsy are subtypes of idiopathic generalized epilepsy (EIG). For a general phenotypic description and a discussion of genetic heterogeneity of these disorders, see EIG (600669), EJM (254770), and EJA (607631). (607628)
