Epileptic individuals are faced with seizures, which are largely caused by enhanced neuronal excitability and/or decreased neuronal inhibitory activity. <i>SCN2A</i> encodes a neuronal voltage-gated sodium channel, Na_V1.2 that is primarily found in excitatory neurons throughout the brain. Na_V1.2 is most concentrated within the principal neurons of the corticostriatal circuit, which includes pyramidal neurons in the medial prefrontal cortex and medium spiny neurons in the striatum. In the early stage of adult development, the Na_V1.2 channel plays critical roles in generation and propagation of action potentials in these neurons. Gain of Function variants of <i>SCN2A</i> results in unprovoked seizures and epilepsy, while loss-of-function variants of <i>SCN2A</i> is a leading cause for autism spectrum disorder as well as intellectual disability. Previous studies have shown that full deletion of <i>Scn2a</i> gene in mice is lethal and partial disruption of <i>Scn2a</i> gene (less than 50%) leads to inhibition of neuronal excitability. A recent study from Dr. Yang's laboratory revealed an unexpected result from mice with severe Na_V1.2 deficiency and they demonstrated that severe deletion of <i>Scn2a</i> gene (around 68% gene disruption) in Na_V1.2 triggers neuronal hyperexcitability in adult mice. Their findings may explain the puzzling clinical observation that certain individuals with Na_V1.2 deficiency still develop unprovoked seizure.
