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.

Likely benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

Lurie Children's Hospital of ChicagoMar 30, 2021NOD2 NM_022162.2 exon 4 p.Arg311Trp (c.931C>T):This variant has been reported in the literature in at least 3 individuals with autoimmune related disease (e.g. Crohn's disease, ulcerative colitis, Behcet's disease), with most authors suggesting this variant may act as a risk allele (Lesage 2002 PMID:11875755, Rivas 2011 PMID:21983784, Burillo-Sanz 2017 PMID:28814775). This variant is present in 0.1% (30/18870) of East Asian alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs104895427). This variant is present in ClinVar (Variation ID:97885). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
NOD2-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesSep 09, 2024The NOD2 c.931C>T variant is predicted to result in the amino acid substitution p.Arg311Trp. This variant has been identified in patients with Cohn’s disease and ulcerative colitis (Lesage et al. 2002. PubMed ID: 11875755; Rivas et al. 2011. PubMed ID: 21983784). Additional functional studies that analyzed basal activity and the ability to respond to PGN determined the p.Arg311Trp variant was indistinguishable from wildtype samples (Chamaillard et al. 2003. PubMed ID: 12626759). In addition, this variant has also been identified in patients with aggressive periodontitis and Behcet’s disease (Burillo-Sanz et al. 2017. PubMed ID: 28814775; Sudo et al. 2017. PubMed ID: 28682159). This variant is reported in 0.16% of alleles in individuals of East Asian descent in gnomAD and is reported in the homozygous state in one individual of Latino descent, which may be too common to be causative of disease. This variant has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from likely benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/97885/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
