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]

Familial cold autoinflammatory syndrome 2

Likely benign, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	- -
Likely benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Sep 08, 2023	The NLRP12 c.3046C>T; p.Arg1016Ter variant (rs35064500) is present in the African population with an allele frequency of 1.6% (401/24,956 alleles including 3 homozygotes) in the Genome Aggregation Database. To our knowledge, the variant has not been reported in any individuals with familial cold autoinflammatory syndrome, but has been reported in individuals with unrelated or non-specific conditions (Modi 2017, Ung 2017, Glicksberg 2019, El Naofal 2023) and is listed in the ClinVar Database (Variation ID: 330001). This variant results in a premature termination codon in the penultimate exon of the NLRP12 gene and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Although the allele frequency of this variant may be incompatible with autosomal dominant familial autoinflammatory syndrome, given the lack of clinical and functional data, the significance of the p.Arg1016Ter variant is uncertain at this time.
