ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001269323 SCV002050258 uncertain significance Familial cold autoinflammatory syndrome 2 2020-12-16 criteria provided, single submitter clinical testing The NLRP12 c.1952C>A; p.Ser651Ter variant (rs781361326), to our knowledge, is not reported in the medical literature or gene-specific databases. This variant is found on only four chromosomes (4/251382 alleles) in the Genome Aggregation Database. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. While loss-of-function variants in NLRP12 have been reported in individuals affected with autoinflammatory disease or periodic fever syndromes (Hua 2019, Jeru 2008, Kostik 2018, Xia 2016), the mechanism by which such variants cause disease remains uncertain (Tuncer 2014). Due to limited information, the clinical significance of the p.Ser651Ter variant is uncertain at this time. References: Hua Y et al.
