Genes affected
NLRP3 (HGNC:16400): (NLR family pyrin domain containing 3) This gene encodes a pyrin-like protein containing a pyrin domain, a nucleotide-binding site (NBS) domain, and a leucine-rich repeat (LRR) motif. This protein interacts with the apoptosis-associated speck-like protein PYCARD/ASC, which contains a caspase recruitment domain, and is a member of the NLRP3 inflammasome complex. This complex functions as an upstream activator of NF-kappaB signaling, and it plays a role in the regulation of inflammation, the immune response, and apoptosis. The SARS-CoV 3a protein, a transmembrane pore-forming viroporin, has been shown to activate the NLRP3 inflammasome via the formation of ion channels in macrophages. Mutations in this gene are associated with familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), chronic infantile neurological cutaneous and articular (CINCA) syndrome, neonatal-onset multisystem inflammatory disease (NOMID), keratoendotheliitis fugax hereditarian, and deafness, autosomal dominant 34, with or without inflammation. Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. Alternative 5' UTR structures are suggested by available data; however, insufficient evidence is available to determine if all of the represented 5' UTR splice patterns are biologically valid.

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 11 ACMG points.
PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_001243133.2
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the NLRP3 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 55 curated pathogenic missense variants (we use a threshold of 10). The gene has 10 curated benign missense variants. Gene score misZ: 2.1417 (below the threshold of 3.09). Trascript score misZ: 3.5037 (above the threshold of 3.09). GenCC associations: The gene is linked to familial cold autoinflammatory syndrome, keratitis fugax hereditaria, cryopyrin-associated periodic syndrome, Muckle-Wells syndrome, familial cold autoinflammatory syndrome 1, CINCA syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.967
PP5

Cryopyrin associated periodic syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 30, 2024 | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 527 of the NLRP3 protein (p.Glu527Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with NLRP3-related disease (PMID: 16081838, 20472245, 26245507, 29378952). This variant is also known as p.Glu525Lys. ClinVar contains an entry for this variant (Variation ID: 97939). 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 NLRP3 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. - |
