Abstract
Background: Variants of the NUS1 gene have recently been linked to a spectrum of phenotypes including epilepsy, cerebellar ataxia, cortical myoclonus and intellectual disability (ID), and primary congenital defects of glycosylation.
Case report: We report a case of myoclonus epilepsy, mild cerebellar ataxia, and ID due to a new de-novo NUS1 missense variant (c.868C>T, p.R290C), and review the current literature of NUS1-associated clinical phenotypes.
Discussion: Pathogenic variants of NUS1 are found in a rapidly growing number of cases diagnosed with myoclonus epilepsy and/or myoclonus-ataxia syndrome. NUS1 should be included in the genetic screening of undiagnosed forms of myoclonus, myoclonus-ataxia, and progressive myoclonus epilepsies.
