Labcorp Genetics (formerly Invitae), Labcorp RCV001317565 SCV001508234 uncertain significance Periodic fever-infantile enterocolitis-autoinflammatory syndrome; Familial cold autoinflammatory syndrome 4 2024-12-24 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 148 of the NLRC4 protein (p.Arg148His). This variant is present in population databases (rs377088692, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with NLRC4-related conditions. ClinVar contains an entry for this variant (Variation ID: 1018286). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on NLRC4 protein function. 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.
