Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PP3_ModerateBS2
The NM_001370466.1(NOD2):c.1957G>A(p.Gly653Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000185 in 1,460,412 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. G653E) has been classified as Uncertain significance.

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 680 of the NOD2 protein (p.Gly680Arg). This variant is present in population databases (rs371339573, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with NOD2-related conditions. ClinVar contains an entry for this variant (Variation ID: 462698). 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 expected to disrupt NOD2 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects NOD2 function (PMID: 15044951). 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. -
