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.

Collection Method:clinical testing

The NOD2 c.746A>G; p.Glu249Gly variant (rs117836686), to our knowledge, is not reported in the medical literature or gene specific databases. The variant is reported in the ClinVar database (Variation ID: 531608) and is found in the European (non-Finnish) population with an allele frequency of 0.03% (39/129,102 alleles) in the Genome Aggregation Database. The glutamic acid at codon 249 is highly conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Due to limited information, the clinical significance of the p.Gly249Gly variant is uncertain at this time. -
