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 aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 113 of the NOD2 protein (p.Asp113Asn). This variant is present in population databases (rs104895468, gnomAD 0.01%). This missense change has been observed in individual(s) with Crohn disease (PMID: 15024686). ClinVar contains an entry for this variant (Variation ID: 97876). 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 NOD2 protein function with a negative predictive value of 95%. Experimental studies have shown that this missense change does not substantially affect NOD2 function (PMID: 26500656). 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. -
