Genes affected

NOD2 (HGNC:5331): (nucleotide binding oligomerization domain containing 2) This gene is a member of the Nod1/Apaf-1 family and encodes a protein with two caspase recruitment (CARD) domains and six leucine-rich repeats (LRRs). The protein is primarily expressed in the peripheral blood leukocytes. It plays a role in the immune response to intracellular bacterial lipopolysaccharides (LPS) by recognizing the muramyl dipeptide (MDP) derived from them and activating the NFKB protein. Mutations in this gene have been associated with Crohn disease and Blau syndrome. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 587 of the NOD2 protein (p.Arg587His). This variant is present in population databases (rs373185098, gnomAD 0.007%). 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: 570145). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt NOD2 protein function with a negative predictive value of 95%. This variant disrupts the p.Arg587 amino acid residue in NOD2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 17968944, 30693132, 32647028). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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.
