ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV000214584	SCV000604551	pathogenic	not provided	2018-01-24	criteria provided, single submitter	clinical testing	The NLRP3 c.1049C>T;p.Thr350Met (rs151344629), also known as Thr348Met, is published in the literature in individuals with various periodic fever syndromes (Kuemmerle-Deschner 2011, Kuemmerle-Deschner 2015). The variant has been described both as occurring de novo and as segregating with disease (Dode 2002, Kanariou 2014). The variant is listed as pathogenic in the ClinVar database (Variation ID: 97909). The variant is not listed in the general population databases (Exome Variant Server, Exome Aggregation Consortium), indicating it is not a common polymorphism. The threonine at codon 350 is moderately conserved across a variety of species and computational programs (Align GVGD, SIFT) predict this variant is deleterious to protein function. Considering available information, this variant is classified as pathogenic. Pathogenic NLRP3 variants are causative for autosomal dominant Muckle-Wells syndrome (MIM#606416).

Invitae	RCV000540218	SCV000646260	pathogenic	Cryopyrin associated periodic syndrome	2022-11-22	criteria provided, single submitter	clinical testing	For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects NLRP3 function (PMID: 16100350, 25730877). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 97909). This variant is also known as p.Thr348Met. This missense change has been observed in individual(s) with clinical features of NLRP3-related conditions (PMID: 11992256, 16100350, 17178739, 20472245, 21356079, 23442610, 25730877, 26245507, 26531310, 26931528). In at least one individual the variant was observed to be de novo. It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 350 of the NLRP3 protein (p.Thr350Met).
