Epilepsy and premature mortality driven by inhibitory neuron dysfunction in a mouse model of SCN1A gain-of-function neurodevelopmental disorder

The gene most commonly implicated in epilepsy, SCN1A, encodes the neuronal voltage-gated sodium channel subunit NaV1.1. SCN1A variants that reduce sodium current (''loss of function'' variants) cause Dravet syndrome, a neurodevelopmental disorder defined by treatment-resistant temperature sensitive epilepsy with onset at/around 5 months of age, developmental delay/intellectual disability, and…
