Two patients with a grin2a mutation and childhood-onset epilepsy

Background N-methyl-d-aspartate is a key neurotransmitter within the central nervous system and its dysfunction can play an important role in epilepsy. Mutations of genes involving the N-methyl-d-aspartate receptor have been implicated in a wide variety of neuropsychiatric disorders including epilepsy, specifically, within the glutamate receptor ionotropic N-methyl-d-aspartate 2A (GRIN2A). Patients We report two patients with a glutamate receptor ionotropic N-methyl-d-aspartate 2A mutation who presented with epilepsy. Conclusions Individuals with a glutamate receptor ionotropic N-methyl-d-aspartate 2A mutation exhibit a broad clinical spectrum.
