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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2024The c.3028C>A (p.Q1010K) alteration is located in exon 9 (coding exon 9) of the GRIN3A gene. This alteration results from a C to A substitution at nucleotide position 3028, causing the glutamine (Q) at amino acid position 1010 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
