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]

Submissions by phenotype

Familial cold autoinflammatory syndrome 2 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeOct 28, 2022This variant is present in population databases (no rsID available, gnomAD 0.01%). 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. ClinVar contains an entry for this variant (Variation ID: 536931). This variant has not been reported in the literature in individuals affected with NLRP12-related conditions. This sequence change creates a premature translational stop signal (p.Leu880Glnfs*15) in the NLRP12 gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in NLRP12 cause disease. -
