Summaries for Epilepsy, Idiopathic Generalized 9

UniProtKB/Swiss-Prot : 75 Epilepsy, idiopathic generalized 9: 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 myoclonic epilepsy 6: 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 9, is also known as epilepsy, idiopathic generalized, susceptibility to, 9. An important gene associated with Epilepsy, Idiopathic Generalized 9 is CACNB4 (Calcium Voltage-Gated Channel Auxiliary Subunit Beta 4). Affiliated tissues include brain, and related phenotypes are eeg with polyspike wave complexes and morning myoclonic jerks

OMIM : 57 For a general phenotypic description and a discussion of genetic heterogeneity of idiopathic generalized epilepsy, see 600669. Juvenile myoclonic epilepsy is a subtype of idiopathic generalized epilepsy; see 254770 for a general phenotypic description and a discussion of genetic heterogeneity of JME. (607682)
