ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV001002580 SCV001160553 likely pathogenic not specified 2019-05-18 criteria provided, single submitter clinical testing The NLRP3 c.908G>A; p.Gly303Asp variant (rs180177441), also published as c.902G>A; p.Gly301Asp on NM_001243133.1, is reported in the medical literature and a gene-specific database in at least two individuals with CAPS (see link below, Han 2019). The variant is listed in the ClinVar database (Variation ID: 97978) but is absent from general population databases (Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. The amino acid at this position is highly conserved and computational algorithms predict this variant is deleterious. Additionally, this amino acid is located in the extended Walker B motif in the NACHT domain, critical in ATP hydrolysis (MacDonald 2013). Considering available information, this variant is classified as likely pathogenic. References: Link to NLRP3-specific database: Han et al.
