Summaries for Epilepsy, Childhood Absence 1

OMIM : 57 Childhood absence epilepsy (CAE, ECA), a subtype of idiopathic generalized epilepsy (EIG; 600669), is characterized by a sudden and brief impairment of consciousness that is accompanied by a generalized, synchronous, bilateral, 2.5- to 4-Hz spike and slow-wave discharge (SWD) on EEG. Seizure onset occurs between 3 and 8 years of age and seizures generally occur multiple times per day. About 70% of patients experience spontaneous remission of seizures, often around adolescence. There are no structural neuropathologic findings in patients with ECA (Crunelli and Leresche, 2002). (600131)

MalaCards based summary : Epilepsy, Childhood Absence 1, also known as epilepsy, childhood absence, 1, is related to childhood absence epilepsy and epilepsy, idiopathic generalized, and has symptoms including absence seizures An important gene associated with Epilepsy, Childhood Absence 1 is ECA1 (Epilepsy, Childhood Absence 1). Related phenotypes are generalized tonic-clonic seizures and absence seizures
