Researchers have, since Dravet syndrome was identified more than 30 years ago, learned Dravet syndrome cases are caused by a genetic mutation that impedes function in a gene known as SCN1A. The gene produces a protein called Nav1.1. that controls the electrical properties of neurons in the brain, and children with Dravet syndrome do not produce enough of the protein to control this electric activity (epileptic seizures result from a disturbance in electric activity in the brain).
