The variant is listed in the ClinVar database (Variation ID: 2540), and is observed in the general population at an overall frequency of 0.19% (561/282870 alleles) in the Genome Aggregation Database. Based on available information, this variant is considered to be pathogenic. Pathogenic MEFV variants are causative for familial Mediterranean fever (MIM: 608107). References: Camus D et al.

Invitae	RCV000002649	SCV000629038	pathogenic	Familial Mediterranean fever	2024-01-31	criteria provided, single submitter	clinical testing	This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 726 of the MEFV protein (p.Val726Ala). This variant is present in population databases (rs28940579, gnomAD 4%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with familial Mediterranean fever (PMID: 9288758, 10879615, 11977178). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It is commonly reported in individuals of Ashkenazi Jewish or Middle Eastern ancestry (PMID: 11464238, 15745878, 23907647). ClinVar contains an entry for this variant (Variation ID: 2540). 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 alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Experimental studies have shown that this missense change affects MEFV function (PMID: 21600797). For these reasons, this variant has been classified as Pathogenic.
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000002649	SCV000711424	likely pathogenic	Familial Mediterranean fever	2022-06-23	criteria provided, single submitter	clinical testing	The p.Val726Ala (NM_000243.2 c.2177T>C) variant in MEFV has been reported in >150 homozygous or compound heterozygous individuals with Familial Mediterranean Fever and related disorders (Neocleous 2015 PMID: 25393764, Moradian 2010 PMID: 20485448, Moradian 2014 PMID: 23907647, Beheshtian 2016 PMID: 27659338, Neocleous 2016 PMID: 27994174, Coşkun 2015 PMID: 26690517, FMF consortium 1997 PMID: 9288094, Unal 2010 PMID: 20483145, Cosan 2010 PMID: 20669279, Camus 2012 PMID: 21995303, Shinar 2012 PMID: 22532615), often associated with a more mild form of disease. Additionally, there are >200 individuals with Familial Mediterranean Fever who are heterozygous for p.Val726Ala and for whom a second MEFV allele has not been identified. This variant has been identified in 0.96% and up to 4.6% of healthy controls from the matched population from these studies (Moradian 2014 PMID: 23907647, Beheshtian 2016 PMID: 27659338) and has been identified in 3.96% (402/10152) of Ashkenazi Jewish chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs28940579). Although this variant is common in specific subpopulations, the allele frequency in cases is statistically significantly increased compared to a healthy population suggesting a causative role; in the Armenian population, the frequency of this variant in healthy individuals was 4.60% compared to 27.98% in affected individuals. This variant has also been reported in ClinVar (Variation ID#2540) as pathogenic by multiple laboratories. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In vitro functional studies of the protein domain containing p.Val726Ala variant report an impact to protein binding (Chae 2006 PMID: 21600797). In summary, although the population in specific subpopulations is high, the p.Val726Ala variant is pathogenic for autosomal recessive Familial Mediterranean Fever.

Ambry Genetics	RCV000623003	SCV000741066	pathogenic	Inborn genetic diseases	2023-09-22	criteria provided, single submitter	clinical testing	The c.2177T>C (p.V726A) alteration is located in exon 10 of the MEFV gene. This alteration results from a T to C substitution at nucleotide position 2177, causing the valine (V) at amino acid position 726 to be replaced by an alanine (A). Based on data from gnomAD, the C allele has an overall frequency of 0.2% (561/282870) total alleles studied. The highest observed frequency was 3.93% (407/10368) of Ashkenazi Jewish alleles. This alteration is considered to be one of five common founder mutations in a number of ethnic populations, including Ashkenazi Jewish, and is associated with a milder familial Mediterranean fever (FMF) phenotype (Touitou, 2001). This alteration has been seen in FMF patients both in heterozygous form and in combination with a second MEFV alteration (Moradian, 2010). This amino acid position is poorly conserved in available vertebrate species. The p.V726 amino acid is located in the PRYSPRY domain of the pyrin protein, which is a globular domain with a binding cavity. 3-D modeling showed that V726 is located on a loop further away from the binding cavity in the lower part of the PRYSPRY domain, and altering it may affect either interaction with other molecules or the folding of this part of the domain (Goulielmos, 2006). This alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, this alteration is classified as pathogenic.
Human Genome Sequencing Center Clinical Lab, Baylor College of Medicine	RCV000002649	SCV000840008	likely pathogenic	Familial Mediterranean fever	2017-07-07	criteria provided, single submitter	clinical testing	This c.2177T>C (p.Val726Ala) variant in the MEFV gene has been reported in multiple patients with familial Mediterranean fever [OMIM: 608107.0003]. Homozygous patients and compound heterozygous patients for this p.Val726Ala variant present with fever, abdominal pain and thoracic pain [PMID 23907647]. This variant has been detected in 224 heterozygous and 6 homozygous individuals from the ExAC population database (http://exac.broadinstitute.org/variant/16-3293310-A-G); no phenotypic information is available for the homozygous individuals. Valine at amino acid position 726 of the MEFV protein is not well conserved in mammals and computer-based algorithms predict this p.Val726Ala change to be benign. Thus, this variant is classified as likely pathogenic. Apparent homozygosity of this variant may be caused by the presence of the mutant allele on both chromosomes of this individual, or the presence of a mutant allele on one allele and an exonic deletion on the opposite allele. Segregation analysis such as parental study is recommended to resolve the apparent homozygosity of this variant in this individual.

This variant has been reported in several publications, including a Genereviews entry describing this variant as disease causing (International FMF Consortium 1997 PMID:8288758, Moradian 2014 PMID:23907647, Shothat 2016 PMID:20301405). This variant is present in 4% (407/10368) of Ashkenazi Jewish alleles including 8 homozygotes in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/16-3293310-A-G?dataset=gnomad_r2_1). Please note, disease causing variants may be present in control databases at low frequencies, reflective of the general population, carrier status and/or variable expressivity. This variant is present in ClinVar, with several labs classifying this variant as pathogenic (Variation ID:2540). In summary, this variant is classified as pathogenic based on the data above.
Illumina Laboratory Services, Illumina	RCV000002649	SCV000914715	pathogenic	Familial Mediterranean fever	2018-09-24	criteria provided, single submitter	clinical testing	The MEFV c.2177T>C (p.Val726Ala) variant is one of the most common pathogenic variants known to cause familial Mediterranean fever (FMF) and is well-documented in the literature. Across a selection of available literature, the p.Val726Ala variant has been identified in at least 110 probands in a homozygous state and 21 probands in a compound heterozygous state (International FMF Consortium, 1997; Mattit et al. 2006; Bektas et al. 2008; Moradian et al. 2014). The frequency of the p.Val726Ala variant is significantly higher in FMF probands than in controls, and has been reported in 14-28% of proband alleles and 2.3-4.6% of control alleles in two studies (Mattit et al. 2006; Moradian et al. 2014). The p.Val726Ala variant is reported at a frequency of 0.004021 in the Other population of the Genome Aggregation Database. Based on the evidence, the p.Val726Ala variant is classified as pathogenic for familial Mediterranean fever. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.

The valine residue is weakly /conserved (11/97 vertebrates, UCSC), and is located in the SPRY domain. There is a moderate physicochemical difference between valine and alanine. The highest population minor allele frequency in the population database gnomAD v2.1 is 3.9% (407/10,368 alleles, 8 homozygotes) in the Ashkenazi Jewish population, while the highest continental population frequency is 0.09% (115/129,180 alleles, 1 homozygote) in the European (non-Finnish) population. This is the third most commonly occurring variant reported in familial Mediterranean fever (FMF) cases (PMID: 36076017). It has been identified in individuals with FMF in the homozygous state and compound heterozygous with a second pathogenic variant, and segregates with disease in multiple families (PMID: 11977178, 21995303, 34988684). However, the variant is also commonly detected as a single heterozygous variant when autosomal recessive inheritance is expected suggesting missing heritability (PMID: 20301405). A homozygous FMF-knock-in mouse model of the variant induces spontaneous inflammation that is similar to or more severe that the inflammation observed in FMF patients (PMID: 21600797). Multiple lines of computational evidence predict a benign effect for the missense substitution (6/6 algorithms). Based on the classification scheme RMH Modified ACMG Guidelines v1.5.1, this variant is classified as PATHOGENIC. Following criteria are met: PM3_VeryStrong, PP1_Strong, BP4.
