Other most frequently reported epilepsy syndromes were infantile spasms (n = 48), epilepsy with myoclonic-atonic seizures (also known as Doose syndrome, n = 18), Dravet syndrome (n = 14), glucose transporter 1 (GLUT-1) deficiency (n = 7), Rett syndrome (n = 4), and pyruvate dehydrogenase deficiency (n = 3). Here, SLC2A1 is linked to epilepsy with myoclonic atonic seizures.
