Dravet’s syndrome (DS) is a form of autism and epilepsy in which there is a SCN1A mutation that encodes for VGSC type-1 (NaV1.1) [15], the primary sodium channel in the GABAergic interneurons. Here, SCN1A is linked to encephalopathy, progressive, early-onset, with brain edema and/or leukoencephalopathy.
