Labcorp Genetics (formerly Invitae), Labcorp RCV003066618 SCV003444273 uncertain significance Periodic fever-infantile enterocolitis-autoinflammatory syndrome; Familial cold autoinflammatory syndrome 4 2024-09-11 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 278 of the NLRC4 protein (p.Thr278Ile). This variant is present in population databases (no rsID available, gnomAD 0.002%). 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: 2139512). 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) indicates that this missense variant is expected to disrupt NLRC4 protein function with a positive predictive value of 80%. 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.
