Labcorp Genetics (formerly Invitae), Labcorp RCV005106281 SCV005732800 pathogenic Cryopyrin associated periodic syndrome 2024-11-21 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 568 of the NLRP3 protein (p.Phe568Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with CINCA syndrome (PMID: 21702021, 24431285, 25584041). In at least one individual the variant was observed to be de novo. This variant is also known as p.Phe566Leu. 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 NLRP3 protein function. This variant disrupts the p.Phe568 amino acid residue in NLRP3. Other variant(s) that disrupt this residue have been observed in individuals with NLRP3-related conditions (PMID: 25584041, 25619352), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic.
