GeneDx RCV000494010 SCV000583075 uncertain significance not provided 2017-05-24 criteria provided, single submitter clinical testing The D60N variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). D60N is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. In summary, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
Invitae RCV000814035 SCV000954427 uncertain significance Cryopyrin associated periodic syndrome 2018-11-08 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with asparagine at codon 60 of the NLRP3 protein (p.Asp60Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with NLRP3-related disease. ClinVar contains an entry for this variant (Variation ID: 430301). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
