Genes affected
NLRP12 (HGNC:22938): (NLR family pyrin domain containing 12) This gene encodes a member of the CATERPILLER family of cytoplasmic proteins. The encoded protein, which contains an N-terminal pyrin domain, a NACHT domain, a NACHT-associated domain, and a C-terminus leucine-rich repeat region, functions as an attenuating factor of inflammation by suppressing inflammatory responses in activated monocytes. Mutations in this gene cause familial cold autoinflammatory syndrome type 2. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2013]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 286 of the NLRP12 protein (p.Pro286Leu). This variant is present in population databases (rs201940393, gnomAD 0.04%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with clinical features of NLRP12-related conditions (PMID: 34725261, 38343435). ClinVar contains an entry for this variant (Variation ID: 536927). 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 NLRP12 protein function with a positive predictive value of 80%. 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. -

NLRP12 NM_144687.3 exon3 p.Pro286Leu (c.857C>T): This variant has not been reported in the literature but is present in 0.04% (16/35418) of Latino alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/19-54314056-G-A?dataset=gnomad_r2_1). This variant is present in ClinVar (Variation ID:536927). 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. -
