FamilieSCN2A Foundation

Cycle 2

The SCN2A gene is located on the long (q) arm of chromosome 2 at position 24.3. SCN2A encodes instructions to make a protein in the brain called a sodium channel which plays a key role in a cell’s ability to generate and transmit electrical signals. Pathogenic variants that affect the SCN2A sodium channel impair the flow of sodium ions in the brain. A deletion or mutation of this gene can cause autism, epilepsy, and other neurological issues, such as movement disorders, dystonia, and dysautonomia.
