Labcorp Genetics (formerly Invitae), Labcorp RCV003780084 SCV004603980 pathogenic Blau syndrome; Regional enteritis 2024-04-17 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 383 of the NOD2 protein (p.Glu383Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with Blau syndrome (PMID: 28639104, 28836875). It has also been observed to segregate with disease in related individuals. 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 expected to disrupt NOD2 protein function with a positive predictive value of 95%. This variant disrupts the p.Glu383 amino acid residue in NOD2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 15812565, 18718560, 19479836, 20565245). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
