Genes affected
GRIN2A (HGNC:4585): (glutamate ionotropic receptor NMDA type subunit 2A) This gene encodes a member of the glutamate-gated ion channel protein family. The encoded protein is an N-methyl-D-aspartate (NMDA) receptor subunit. NMDA receptors are both ligand-gated and voltage-dependent, and are involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. These receptors are permeable to calcium ions, and activation results in a calcium influx into post-synaptic cells, which results in the activation of several signaling cascades. Disruption of this gene is associated with focal epilepsy and speech disorder with or without cognitive disability. Alternative splicing results in multiple transcript variants.

ACMG classification
Classification made for transcript
Verdict is Uncertain_significance. Variant got 5 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the GRIN2A gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 92 curated pathogenic missense variants (we use a threshold of 10). The gene has 175 curated benign missense variants. Gene score misZ: 2.8278 (below the threshold of 3.09). Trascript score misZ: 3.7088 (above the threshold of 3.09). GenCC associations: The gene is linked to early-onset epileptic encephalopathy and intellectual disability due to GRIN2A mutation, Landau-Kleffner syndrome, continuous spikes and waves during sleep, complex neurodevelopmental disorder, rolandic epilepsy-speech dyspraxia syndrome, childhood epilepsy with centrotemporal spikes.
