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.

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 expected to disrupt NLRP3 protein function. ClinVar contains an entry for this variant (Variation ID: 570991). This missense change has been observed in individual(s) with cryopyrin associated periodic syndrome (CAPS) (PMID: 29239927). This variant is present in population databases (rs745564372, gnomAD 0.01%). This sequence change replaces glutamic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 607 of the NLRP3 protein (p.Glu607Val). -

NLRP3 NM_004895.4 exon 3 p.Glu607Val (c.1820A>T): This variant has not been reported in the literature but is present in 5/33582 Latino alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs745564372). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
