GeneDx RCV001733437 SCV001983817 uncertain significance not provided 2021-10-13 criteria provided, single submitter clinical testing Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; Also known as p.L239F; This variant is associated with the following publications: (PMID: 19302049)
Genome Diagnostics Laboratory, The Hospital for Sick Children RCV002264383 SCV002542643 uncertain significance Autoinflammatory syndrome 2020-03-01 criteria provided, single submitter clinical testing
Invitae RCV002543911 SCV003323658 uncertain significance Cryopyrin associated periodic syndrome 2024-01-29 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 241 of the NLRP3 protein (p.Leu241Phe). This variant is present in population databases (rs770294045, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with NLRP3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1301429). 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) has been performed at Invitae 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. 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.
