Background: Mutations in SCN1A , the gene encoding the α1 subunit of the sodium channel, have been found in severe myoclonic epilepsy of infancy (SMEI) and generalized epilepsy with febrile seizures plus (GEFS+). Mutations in SMEI include missense, nonsense, and frameshift mutations more commonly arising de novo in affected patients. This finding is difficult to reconcile with the family

It is characterized by multiple febrile seizures, often prolonged, subsequent development of uncontrollable mixed‐myoclonic seizures, and, eventually, psychomotor retardation. Drugs for myoclonic epilepsy–valproate (VPA), the suximides, and the benzodiazepines–have been shown to be useful in Epileptic syndromes that cause myoclonic seizures usually begin in early childhood, and last throughout life, though milder forms may improve with adulthood. Doose syndrome (myoclonic-atonic epilepsy), Dravet syndrome (severe myoclonic epilepsy of infancy [SMEI]) and Lennox-Gastaut syndrome are all childhood epilepsy syndromes that may cause seizures in babies and toddlers. AHC starts in infancy and presents with episodes of hemiplegia and often hemidystonia. It usually evolves with epilepsy and loss of developmental milestones, and often persistent movement disorder. The RDP phenotype does not usually cause paroxysmal dystonia, but persistent dystonia and/or parkinsonism of subacute onset.
