Genes affected

GRIN2D (HGNC:4588): (glutamate ionotropic receptor NMDA type subunit 2D) 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).

Invitae

Jul 19, 2023

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GRIN2D protein function. ClinVar contains an entry for this variant (Variation ID: 1517040). This variant has not been reported in the literature in individuals affected with GRIN2D-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.04%). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 3 of the GRIN2D protein (p.Gly3Ser). -
