Dravet syndrome (DS) is a developmental and epileptic encephalopathy, with significant risk of mortality due to sudden unexpected death in epilepsy patients (SUDEP) or status epilepticus [1]. Our previous work demonstrated 58% genetic yield of underlying variant in the alpha 1 subunit of the sodium channel encoded by the SCN1A gene in North Indian cohort [2]. Other important reported causative genetic variants in DS are SCN2A, SCN1B, PCDH19 [3].
