GRIN2A

N-methyl-D-aspartate (NMDA) receptors are a class of ionotropic glutamate receptors. NMDA channel has been shown to be involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. NMDA receptor channels are heteromers composed of the key receptor subunit NMDAR1 (GRIN1) and 1 or more of the 4 NMDAR2 subunits: NMDAR2A (GRIN2A), NMDAR2B (GRIN2B), NMDAR2C (GRIN2C), and NMDAR2D (GRIN2D).^[8]

Variants of the gene are associated with the protective effect of coffee on Parkinson's disease.^[9][10]

Mutations in GRIN2A are associated to refractory epilepsy.^[11]

Whole exome/genome sequencing has led to the discovery of an association between mutations in GRIN2A and a wide variety of neurological diseases, including epilepsy, intellectual disability, autism spectrum disorders, developmental delay, and schizophrenia.^{[12][13][14][15]}

GRIN2A has been shown to interact with:
