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.

The NOD2 c.1190C>T, p.Pro397Leu variant (rs150078153) is reported in one individual with a systemic auto-inflammatory disease (Rusmini 2016), and one individual with Chron’s disease (Zouiten-Mekki 2005). However, neither patient had clear disease association. The variant is reported in the ClinVar database (Variant ID 531599) and is listed in the general population with an overall allele frequency of 0.02% (44/282,784 alleles) in the Genome Aggregation Database. The proline at codon 397 is highly conserved, but computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.44). Due to limited information, the clinical significance of the p.Pro397Leu variant is uncertain at this time. References: Rusmini M et al. Next-generation sequencing and its initial applications for molecular diagnosis of systemic auto-inflammatory diseases. Ann Rheum Dis. 2016 Aug;75(8):1550-7. PMID: 26386126. Zouiten-Mekki L et al.

This 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. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

The NOD2 c.1190C>T variant is predicted to result in the amino acid substitution p.Pro397Leu. This variant has been reported in an individual with ulcerative colitis (Table S3, Horowitz et al. 2021. PubMed ID: 33692434) as well as, along with a truncating NPC1 variant, a patient with an atypical form of Crohn's disease with neurological deterioration present (Azab et al. 2022. PubMed ID: 35741735). This variant is reported in 0.027% of alleles in individuals of European (non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This 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). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
