Associated with relevant phenotype in OMIM, but not associated with phenotype in Gen2Phen, although there is a confirmed association with epileptic encephalopathy in Gen2Phen. At least 20 variants have been associated with Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal dominant OMIM:614254 and three have been associated with Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal recessive OMIM:617820.Created: 14 Sep 2021, 5:52 p.m. | Last Modified: 14 Sep 2021, 5:52 p.m.

Over 20 individuals reported with de novo missense variants in GRIN1 and severe neurodevelopmental phenotype, comprising ID, seizures, and a movement disorder, in particular dystonia. Two families reported with bi-allelic variants: different mechanism postulated (LOF vs affecting channel functioning or hypomorphic alleles), parents were carriers and unaffected. Movement disorder, in particular dystonia also reported in bi-allelic cases.
