For those receiving IEP services, the public school district is required to provide services until age 21. Given that all probands with autosomal dominant GRIN1-NDD reported to date have the disorder as a result of a de novo Gorlin syndrome does not affect life expectancy. Molecular diagnosis of patients with epilepsy and developmental delay using a customized panel of epilepsy genes. A combination of seizure medications is typically used to control the different seizure types. Autosomal dominant and autosomal recessive inheritance. Because the phenotype of GRIN1-related neurodevelopmental disorder is often nonspecific and indistinguishable from many other inherited disorders, it is most likely to be diagnosed by either gene-targeted testing (i.e., a multigene panel) (see Option 1) or genomic testing (which does not require the clinician to determine which gene is likely involved) (see Option 2).
