Function	"Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient"
Mutation
Disease	"DISEASE: Seizures, benign familial infantile, 3 (BFIS3) [MIM:607745]: A form of benign familial infantile epilepsy, a neurologic disorder characterized by afebrile seizures occurring in clusters during the first year of life, without neurologic sequelae BFIS3 inheritance is autosomal dominant Note=The disease is caused by mutations affecting the gene represented in this entry ; DISEASE: Epileptic encephalopathy, early infantile, 11 (EIEE11) [MIM:613721]: An autosomal dominant seizure disorder characterized by neonatal or infantile onset of refractory seizures with resultant delayed neurologic development and persistent neurologic abnormalities Patients may progress to West syndrome, which is characterized by tonic spasms with clustering, arrest of psychomotor development, and hypsarrhythmia on EEG Note=The disease is caused by mutations affecting the gene represented in this entry ; DISEASE: Note=Defects in SCN2A are associated with autism spectrum disorders (ASD) It seems that mutations resulting in sodium channel gain of function and increased neuron excitability lead to infantile seizures, whereas variants resulting in sodium channel loss of function and decrease neruon excitability are associated with ASD"
