RCV000224634 | SCV000490471 | uncertain significance | not provided | 2020-01-10 | criteria provided, single submitter | clinical testing | Published functional studies demonstrate that the V200M variant results in moderate increase of interleukin-1 beta secretion, and NLRP3/cryopyrin inflammosome activation (Yuksel et al., 2014); Is considered by some as a risk allele or variant with reduced penetrance (Aksentijevich et al., 2007; Yuksel et al., 2014; Kuemmerle-Deschner et al., 2017); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 24123366, 26531310, 30407166, 17393462, 24135410, 25988833, 23421920, 12355493, 20159265, 26020059, 25596455, 15334488, 11687797, 17038455, 22566169, 27994174, 29159471, 29922587, 28692792, 31858722, 30783801, 31036385, 31769854, 31410474, 14872505) |

RCV000224634 | SCV000604557 | uncertain significance | not provided | 2023-11-10 | criteria provided, single submitter | clinical testing | The NLRP3 c.598G>A; p.Val200Met variant (rs121908147), also known as V198M, is listed in the Genome Aggregation Database with an allele frequency of up to 2.3% (588/25096 alleles, including 6 homozygotes) in the European Finnish population. The valine at codon 200 is weakly conserved and computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.222). The variant is listed in the ClinVar database with conflicting classifications (Variation ID: 4371). This variant is reported in the medical literature in individuals with familial cold-induced autoinflammatory syndrome (FCAS) (MIM:120100) and Muckle-Wells syndrome (MWS) (MIM:191900), both also known as cryopyrin-associated periodic syndromes (CAPS), as well as in patients with other autoinflammatory syndromes, acquired disorders including Schnitzler syndrome, and also in asymptomatic carriers (Aganna 2002, Hoffman 2001, Kuemmerle-Deschner 2017, Rowczenio 2013, Torres 2018, Yuksel 2014). Since p.Val200Met presents with variable expressivity and reduced penetrance, this variant may contribute to the inflammatory diseases processes together with other, presently unidentified, genetic and environmental factors. However, the existence of individuals homozygous for the variant in control databases and the high population frequency suggest this variant is benign. Due to conflicting information, the clinical significance of the p.Val200Met variant is uncertain at this time. References: Aganna E et al.

In some reports, the variant also segregated in other family members with variable clinical features of disease. However, this variant is present in 2.4% (588/25096) of Finnish alleles, including 6 homozygotes in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/1-247587343-G-A?dataset=gnomad_r2_1). This variant is present in ClinVar with several discrepant classifications from "Benign to Variant of Uncertain Significance" (Variation ID:4371). This variant amino acid Methionine (Met) is present in several species and is not well conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. Functional studies suggest that this variant will impact the protein NLRP3/cryopyrin inflammosome (Yuksel 2014 PMID:24135410); however, further studies are needed to understand its impact. Of note, at least 2 authors in the literature suggest that this variant may act as a risk allele or low penetrance variant (Aganna 2002 PMID:12355493, Yuksel 2014 PMID:24135410). In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. |

RCV000248492 | SCV000966485 | likely benign | not specified | 2018-02-10 | criteria provided, single submitter | clinical testing | p.Val200Met in exon 5 of NLRP3: This variant (also reported as p.Val198Met) is n ot expected to have clinical significance because it has been identified in 0.85 % (2343/276948) of the total chromosomes in the Genome Aggregation Database incl uding 19 homozygotes. The highest allele frequency was 2.38% (613/25766) of Fin nish chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broad institute.org; dbSNP rs121908147). The NLRP3 gene is associated with cryopyrin associated periodic syndrome (CAPS) which has an estimated prevalence of 1 in 36 0,000 (Orphanet, http://www.orpha.net, Orpha # 208650). While this variant has been reported in many individuals with features of CAPS and has been reported as a "low-penetrance allele", the variant was also identified in controls and unaf fected family members (Aggana 2002, Rowczenio 2013, Hoffman 2001, Look 2010, Lev y 2015). Furthermore, the frequency of the variant in the affected individuals in several studies was similar to the frequency of the variant in the Genome Agg regation Database (Kone-Paut 2007, Jesus 2012, Rowczenio 2013, Schuh 2015). One study found that in transfected embryonal kidney cells with the p.Val200Met var iant, IL-1? secretion was significantly increased compared to wild-type transfe cted cells (Yuksel 2014). However, another study found that patients with Val19 8Met and other variants described as low-penetrance alleles had similar response s as controls to inflammasome stimulation, compared with patients with clearly p athogenic NLRP3 variants (Rieber 2015). Furthermore, the valine (Val) residue a t position 200 is not conserved through species with >10 mammals having a methio nine (Met) at this position. In summary, due to the high frequency of the varia nt in the general population compared to the low estimated prevalence of CAPS, a nd the absence of enrichment of the variant in affected individuals, this varian t is likely benign.
