Subsequently, BRAT1 mutations were also identified in patients with milder clinical forms including neurodevelopmental disorder with cerebellar atrophy and with or without seizures (NEDCAS, OMIM 618056), epilepsy of infancy with migrating focal seizures (EIMFS), and congenital ataxia (CA)7–10. This evidence concerns the gene BRAT1 and Cerebellar atrophy.
