Genes affected

GRIN3A (HGNC:16767): (glutamate ionotropic receptor NMDA type subunit 3A) This gene encodes a subunit of the N-methyl-D-aspartate (NMDA) receptors, which belong to the superfamily of glutamate-regulated ion channels, and function in physiological and pathological processes in the central nervous system. This subunit shows greater than 90% identity to the corresponding subunit in rat. Studies in the knockout mouse deficient in this subunit suggest that this gene may be involved in the development of synaptic elements by modulating NMDA receptor activity.

The c.2866T>C (p.Y956H) alteration is located in exon 7 (coding exon 7) of the GRIN3A gene. This alteration results from a T to C substitution at nucleotide position 2866, causing the tyrosine (Y) at amino acid position 956 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
