GeneDx	RCV000255083	SCV000321877	pathogenic	not provided	2016-05-02	criteria provided, single submitter	clinical testing	The R653H pathogenic variant in the MEFV that has been previously reported in association with Familial Mediterranean Fever (FMF) (Schaner et al., 2001; Timmann et al., 2001; Booty et al., 2009; Lazarin et al., 2013). It has also been observed in patients with juvenile idiopathic arthritis (Comak et al., 2013). The R653 variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. R653H is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved and in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. However, a missense variant in a nearby residue (E656A) has been reported in the Human Gene Mutation Database in association with FMF (Stenson et al., 2014), supporting the functional importance of this region of the protein.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000002662	SCV000696058	pathogenic	Familial Mediterranean fever	2017-02-23	criteria provided, single submitter	clinical testing	Variant summary: The MEFV c.1958G>A (p.Arg653His) variant located in the SPRY domain (via InterPro) involves the alteration of a non-conserved nucleotide, which 2/3 in silico tools (SNPs&GO and Mutation Taster not captured due to low reliability index and p-value, respectively) predict a benign outcome for this variant, although these predictions have yet to be functionally assessed. This variant was found in 6/121204 control chromosomes at a frequency of 0.0000495, which does not exceed the estimated maximal expected allele frequency of a pathogenic MEFV variant (0.0216506). Multiple publications have cited the variant in affected individuals in whom a second mutation not identified. Of note, this variant was reported in one affected individual who met the Tel-Hashomer criteria for a diagnosis of MEFV as a compound heterozygote along with p.M694V. The unaffected mother and brother were carriers for the variant of interest. In addition, Booty_2009 reports a clinically diagnosed FMF affected sib-pair that each carry only the variant of interest following a comprehensive search for a second mutation in the MEFV gene. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, although no in-vitro or in-vivo functional studies supporting a damaging outcome for this variant have been reported, the ascertained evidence has been weighted to classify this variant as Pathogenic.

Invitae	RCV000002662	SCV001415945	likely pathogenic	Familial Mediterranean fever	2024-01-27	criteria provided, single submitter	clinical testing	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 653 of the MEFV protein (p.Arg653His). This variant is present in population databases (rs104895085, gnomAD 0.01%). This missense change has been observed in individual(s) with familial Mediterranean fever (PMID: 11470495, 16378925, 19479870, 21413889, 24469716, 29159471, 31989427; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 2553). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.

ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV000255083	SCV002048973	likely pathogenic	not provided	2021-02-18	criteria provided, single submitter	clinical testing	The MEFV c.1958G>A; p.Arg653His variant (rs104895085) has been described in the heterozygous state in several individuals with a clinical diagnosis of familial Mediterranean fever and at least once in the compound heterozygous state in an individual with an additional pathogenic variant (Berdeli 2011, Botty 2009, Comak 2013, Jeske 2013, Oztuzcu 2014, Schaner 2001, Shinar 2007, Timmann 2001). The variant is reported in the ClinVar database (Variation ID: 2553) and is listed in the general population with an overall allele frequency of 0.0035% (10/282,580 alleles) in the Genome Aggregation Database. The arginine at codon 653 occurs in the SPRY domain, is weakly conserved, computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.337). However, most pathogenic MEFV variants occur in the SPRY domain (Manukyan 2016). Based on available information, this variant is classified as likely pathogenic. References: Berdeli A et al.
