Scn2a encephalopathy

Web19 Feb 2024 · SCN2A is a high-confidence autism risk gene, which encodes a subunit of a sodium channel in the brain called Nav1.2. When the channel malfunctions, conditions like epilepsy and autism follow. WebHerein, we define the phenotypic spectrum of SCN2A encephalopathy. Methods: Twelve patients with an SCN2A epileptic encephalopathy underwent electroclinical phenotyping. Results: Patients were aged 0.7 to 22 years; 3 were deceased. Seizures commenced on day 1-4 in 8, week 2-6 in 2, and after 1 year in 2.
