(3) In some laboratories, panel options may include a custom laboratory-designed panel and/or custom phenotype-focused exome analysis that includes genes specified by the clinician. Pathogenic variants ("mutations") in the GRIN1 gene cause a spectrum of neurodevelopmental disorders that can include childhood-onset epilepsy, developmental delays, movement disorders, and features of autism spectrum disorder. Clinical features of GRIN-related disorders typically include intellectual disability and epilepsy along with other neurological and/or neuropsychiatric features, such as movement disorders, autism spectrum disorder, and problems with muscle tone.
