Drug-controllable AAV-mediated KCNA1 expression normalized elevated neuronal firing and reduced spontaneous seizure burden in seizure-prone Scn2a-deficient mice on the DBA/2J background.
- Why it matters: SCN2A loss-of-function variants can cause severe, refractory epilepsy, and existing Scn2a-LoF mouse models show few spontaneous seizures, limiting how well therapies can be tested dynamically.
- What they did: The study created gene-trap Scn2a-deficient mice on DBA/2J to yield hundreds of spontaneous absence seizures per day, then used a drug-controllable AAV to express human KCNA1.
- The result: KCNA1 expression normalized elevated firing and lowered spontaneous seizure burden in Scn2a-deficient mice, and in human cortical organoids with a SCN2A-truncating variant it reduced neuronal firing.
