Green List (high evidence)

Over 20 individuals reported with de novo missense variants in GRIN1 and severe neurodevelopmental phenotype, comprising ID, seizures, and a movement disorder. Substantial number reported with PMG, may be related to variant location. Two families reported with bi-allelic variants: different mechanism postulated (LOF vs affecting channel functioning or hypomorphic alleles), parents were carriers and unaffected.
