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 was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

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 CINCA syndrome, Muckle-Wells syndrome, familial cold autoinflammatory syndrome 1, familial cold autoinflammatory syndrome, cryopyrin-associated periodic syndrome, keratitis fugax hereditaria.
BP4
Computational evidence support a benign effect (MetaRNN=0.09353036).
BP6
Variant 1-247444127-A-G is Benign according to our data. Variant chr1-247444127-A-G is described in ClinVar as Likely_benign. ClinVar VariationId is 469053.Status of the report is criteria_provided_single_submitter, 1 stars.
BS2
High AC in GnomAdExome4 at 52 AD gene.
