Scn8a epileptic encephalopathy
WebSCN8A epileptic encephalopathy is caused by de novo, gain-of-function mutations in the gene that encodes the α subunit of the voltage-gated sodium channel Na V 1.6, which is widely expressed in the brain. Na V 1.6 is located at the axon initial segment and nodes of Ranvier of myelinated axons, ... WebIt is necessary to perform sequence analysis to detect a heterozygous pathogenic mutation in the SCN8A gene. Identification of an SCN8A pathogenic variant may have important implications for medical management of the seizure disorder.
