SCN8A-related disorders ( ) are rare genetic neurological conditions caused by mutations affecting sodium channels in the brain. These mutations often lead to early-onset epilepsy, developmental delay, and movement abnormalities.
Symptoms that may suggest SCN8A-related epilepsy include seizures beginning in infancy or early childhood, especially when combined with intellectual disability, autism spectrum disorder, or movement disorders. Seizure onset is typically from birth to 18 months with an average age of onset of 4-5 months.
Seizures associated with SCN8A can be severe and difficult to control, significantly impacting cognitive development and quality of life. Early diagnosis through genetic testing is essential for personalized care planning.
