SCN2A-Related Disorders

The SCN2A gene is like a set of instructions inside the body to help the brain work properly. This gene helps create tiny doorways, called sodium channels, that let electricity flow in and out of brain cells. This electricity is very important because it helps the brain send messages to different parts of the body, like telling hands to move or eyes to blink. If the SCN2A gene has an unexpected change (variant), the tiny doorways don't work properly. This can make it harder for the brain to send messages, which might cause problems like epilepsy (seizures), trouble learning, or difficulty moving.
