Pathogenic variants of the SCN1A gene result in a wide range of disease severities, from severe DS, on one end of the spectrum, to milder pathologies on the other end, such as genetic epilepsy with febrile seizures plus (GEFS+) and the genetic syndrome with febrile seizures (FS or FS+) (5–8). The gene discussed is SCN1A; the disease is Dravet syndrome.
