Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 3P and 1B. PM2PP2BP4
The NM_001134407.3(GRIN2A):c.4126C>G(p.Arg1376Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,461,814 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 11/17 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1376S) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 15, 2019 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with GRIN2A-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with glycine at codon 1376 of the GRIN2A protein (p.Arg1376Gly). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and glycine. - |
