Invitae RCV001928506 SCV002179511 uncertain significance Periodic fever-infantile enterocolitis-autoinflammatory syndrome; Familial cold autoinflammatory syndrome 4 2022-10-13 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with NLRC4-related conditions. 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. 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 not expected to disrupt NLRC4 protein function. ClinVar contains an entry for this variant (Variation ID: 1414057). This variant is present in population databases (rs770505969, gnomAD 0.02%). This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 235 of the NLRC4 protein (p.Met235Thr).

Ambry Genetics RCV003375437 SCV004079729 uncertain significance Inborn genetic diseases 2023-06-30 criteria provided, single submitter clinical testing The c.704T>C (p.M235T) alteration is located in exon 4 (coding exon 3) of the NLRC4 gene. This alteration results from a T to C substitution at nucleotide position 704, causing the methionine (M) at amino acid position 235 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
