Summaries for Myoclonic Epilepsy of Infancy

MalaCards based summary : Myoclonic Epilepsy of Infancy, also known as benign myoclonic epilepsy of infancy, is related to epileptic encephalopathy, early infantile, 6 and gabrg2-related dravet syndrome, and has symptoms including intellectual disability, mild, eeg with irregular generalized spike and wave complexes and generalized myoclonic seizures. An important gene associated with Myoclonic Epilepsy of Infancy is SCN1A (Sodium Voltage-Gated Channel Alpha Subunit 1), and among its related pathways/superpathways are L1CAM interactions and Phase 0 - rapid depolarisation. Affiliated tissues include eye and testes.
