功能：Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. Implicated in the regulation of hippocampal replay occurring within sharp wave ripples (SPW-R) important for memory.

- Review: Dysfunction in SCN2A has been recently recognized as a major cause of neurodevelopmental disorders (NDDs), including epilepsy, intellectual disability (ID), and autism spectrum disorder (ASD). Loss of NaV1.2 function contributes to ASD and ID, whereas gain of function contributes to early onset epilepsy. Sodium channel function can be enhanced or suppressed using pharmacology. PMID: 29691040
- We utilized a targeted next generation sequencing (NGS) approach on a girl with early-onset seizures and Rett-like features, including autistic behavior, limited hand function with chorea, and profound intellectual disability, to identify novel missense mutation (c.1270G>A; p.V424M) in the SCN2A gene, which encodes the alphaII-subunit of the voltage-gated Na+ channel (Nav1.2). PMID: 28709814
- SCN2A autism spectrum disorder (ASD)-associated variants dampened or eliminated channel function in transfected HEK293 cells. A compartmental model of developing excitatory neurons demonstrated that all ASD variants, regardless of their mechanism of action, resulted in deficits in neuronal excitability.
