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]

The c.2013C>A (p.S671R) alteration is located in exon 3 (coding exon 3) of the NLRP12 gene. This alteration results from a C to A substitution at nucleotide position 2013, causing the serine (S) at amino acid position 671 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 862153). This variant has not been reported in the literature in individuals affected with NLRP12-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 671 of the NLRP12 protein (p.Ser671Arg). -
