Genes affected
MVK (HGNC:7530): (mevalonate kinase) This gene encodes the peroxisomal enzyme mevalonate kinase. Mevalonate is a key intermediate, and mevalonate kinase a key early enzyme, in isoprenoid and sterol synthesis. Mevalonate kinase deficiency caused by mutation of this gene results in mevalonic aciduria, a disease characterized psychomotor retardation, failure to thrive, hepatosplenomegaly, anemia and recurrent febrile crises. Defects in this gene also cause hyperimmunoglobulinaemia D and periodic fever syndrome, a disorder characterized by recurrent episodes of fever associated with lymphadenopathy, arthralgia, gastrointestinal dismay and skin rash. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

Pathogenic, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaAug 28, 2017The MVK c.1129G>A (p.Val377Ile) missense variant is very common and occurs in approximately 90% of individuals with hyper IgD syndrome (HIDS) (Messer et al. 2016). Across a selection of the available literature, the p.Val377Ile variant was reported in a total of 28 symptomatic patients with HIDS, including in eight homozygotes, 16 compound heterozygotes, and four heterozygotes in whom a second variant was not identified (Lainka et al. 2012; Parvaneh et al. 2014; Chandrakasan et al. 2014; Moussa et al. 2015; De Pieri et al. 2015; Messer et al. 2016). The p.Val377Ile variant was also reported in five asymptomatic individuals who were either homozygous or compound heterozygous for the variant (Lainka et al. 2012; Messer et al. 2016), though this is consistent with the mild phenotype and reduced penetrance reported by Houten et al. (2003). Control data are not available in these studies, but the variant is reported at a frequency of 0.00221 in the European American population of the Exome Sequencing Project. Based on the collective evidence, the p.Val377Ile variant is classified as pathogenic for hyper IgD syndrome, though many individuals with this variant may present with a mild phenotype or may be asymptomatic. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMay 28, 2016The p.Val377Ile variant in MVK has been identified in 0.14% (170/120,578) of chr omosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.o rg; dbSNP rs28934897). This variant is the most frequent pathogenic variant in Hyperimmunoglobulinaemia D and periodic fever syndrome (HIDS) (Houten 1999, Cuis set 2001, Houten 2003). It has been demonstrated to lead to reduced enzymatic ac tivity in vitro (Houten 1999). In summary, this variant meets our criteria to be classified as pathogenic for hyperimmunoglobulinemia D syndrome (HIDS) in an au tosomal recessive manner, based on biallelic observations in patients and functi onal evidence. -

Pathogenic, criteria provided, single submitterclinical testingKnight Diagnostic Laboratories, Oregon Health and Sciences UniversityMar 30, 2016The c.1129G>A (p.Val377Ile) missense variant in the MVK gene is a known common variant that has been previously reported in numerous individuals affected with Hyper IgD Syndrome (Houten et al., 1999; Houten et al., 2003; Mandey et al., 2006; Gençpınar et al., 2012; Cantarini et al., 2013; Levy et al., 2013; Shendi et al., 2014; Moussa et al., 2015).This variant has also been reported in trans with other known pathogenic variants (His20Pro, Ile1268Thr, Lys13Aspfs*66, Pro167Leu) (Houten et al.,1999; Gençpınar et al., 2012). Functional studies have shown reduced or undetectable mevalonate kinase activity and protein expression in affected individuals, indicating this variant likely affects protein stability and function (Houten et al., 1999). This variant is reported at low frequency in the population databases (Exome Sequencing Project = 0.221%; 1000 Genomes = NA; and ExAC = 0.196%). A reputable clinical diagnostic laboratory (Baylor Miraca Genetics Laboratories) has classified this variant as Pathogenic. Therefore, this collective evidence supports the classification of the c.1129G>A (p.Val377Ile) as a recessive Pathogenic variant for Hyper IgD Syndrome. We have confirmed this finding in our laboratory using Sanger sequencing. -

Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpApr 14, 2023Variant summary: MVK c.1129G>A (p.Val377Ile) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0016 in 249414 control chromosomes, predominantly at a frequency of 0.0023 within the Non-Finnish European subpopulation in the gnomAD database. c.1129G>A has been reported in the literature in multiple individuals affected with Hyper-IgD syndrome (HIDS), including in cases where it was in trans with a pathogenic variant and it has been found to segregate with disease (e.g. Houten_1999, Cuisset_2001, Govindaraj_2020). It is reportedly the most frequently occurring variant identified in HIDS patients (Houten_2003). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function and found that the variant is associated with an MK activity of approximately 40% of WT in E.coli lysates and that it was undetectable by immunoblot in fibroblast lysates from HIDS patients, suggesting it also impacts protein stability (Houten_1999). Multiple clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and the majority classified it as pathogenic (n=27)/likely pathogenic (n=2), with the remaining classifying it as VUS (n=2). Based on the evidence outlined above, the variant was classified as pathogenic. -

Pathogenic, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The MVK p.Val325Ile variant was identified in 23 of 58 proband chromosomes (frequency: 0.43) from individuals or families with hyperimmunoglobulinaemia D and periodic fever syndrome (HIDS) (Houten_1999_PMID:10369261; Cuisset_2001_PMID:11313769). The variant was also identified in dbSNP (ID: rs28934897), ClinVar (classified as pathogenic by Invitae, GeneDx and eight other laboratories) and LOVD 3.0 (classified as pathogenic and likely pathogenic). The variant was identified in control databases in 443 of 280790 chromosomes at a frequency of 0.001578 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European (non-Finnish) in 303 of 128360 chromosomes (freq: 0.002361), Latino in 50 of 35436 chromosomes (freq: 0.001411), European (Finnish) in 33 of 23962 chromosomes (freq: 0.001377), Other in 9 of 7198 chromosomes (freq: 0.00125), South Asian in 28 of 30616 chromosomes (freq: 0.000915), Ashkenazi Jewish in 8 of 10360 chromosomes (freq: 0.000772), African in 10 of 24932 chromosomes (freq: 0.000401), and East Asian in 2 of 19926 chromosomes (freq: 0.0001). The V325I variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. The p.Val325 residue is conserved in mammals but not in more distantly related organisms however four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. However, functional studies expressing cDNA constructs containing the V325I variant in E. coli have demonstrated decreased mevalonate kinase (MK) protein activity compared to wildtype (Houten_1999_PMID:10369261). Decreased MK activity was also found in lymphocytes and fibroblasts from patients with the V325I variant (Houten_1999_PMID:10369261). Interestingly, this variant has been reported in the homozygous state in two sisters, one affected with HIDS and the other who was asymptomatic, therefore suggesting that other genetic factors may influence the presentation of HIDS in individuals with the V325I variant (Messer_2016_PMID:26977311). In summary, based on the above information this variant meets our laboratory’s criteria to be classified as pathogenic. -

Pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesFeb 08, 2024The MVK c.1129G>A variant is predicted to result in the amino acid substitution p.Val377Ile. This is a well-documented pathogenic variant for Hyper-IgD syndrome (HIDS) and has been reported in ~90% of the HIDS cases, both in the homozygous and compound heterozygous states (Messer et al. 2016. PubMed ID: 26977311; Schlabe et al. 2016. PubMed ID: 27899390; Houten et al. 2003. PubMed ID: 12634869). Although, there are occasional reports of this variant in patients with mevalonic aciduria (MA) (Favier and Schulert 2016. PubMed ID: 27499643), functional studies did not indicate a profound enzyme deficiency as expected in patients with MA (Cuisset et al. 2001. PubMed ID: 11313769). In addition, this variant is known for its reduced penetrance, leading to a mild or absent phenotype (Houten et al. 2003. PubMed ID: 12634869). This variant is reported in 0.24% of alleles in individuals of European (Non-Finnish) descent in gnomAD. In ClinVar, it is classified as a pathogenic variant (https://www.ncbi.nlm.nih.gov/clinvar/variation/11929/). Taken together, this variant is considered a pathogenic variant for HIDS, but its role in mevalonic aciduria is uncertain. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 31, 2024This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 377 of the MVK protein (p.Val377Ile). This variant is present in population databases (rs28934897, gnomAD 0.2%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with hyper IgD syndrome (HIDS), and is one of the most commonly reported variants found in HIDS patients (PMID: 10369261, 11313769, 12634869, 15536479, 26977311). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 11929). 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 isoleucine 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 MVK function (PMID: 10369261, 26977311). For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesJul 05, 2018The MVK c.1129G>A;p.Val377Ile variant (rs28934897) is described in the medical literature in both the homozygous and compound heterozygous state in individuals with hyperimmunoglobulin D syndrome (HIDS) with reduced mevalonate kinase activity and has been implicated as the most common pathogenic HIDS variant (Houten 1999, Houten 2003). The variant is listed in the ClinVar database (Variation ID: 11929) and in the Genome Aggregation Database with an allele frequency of 0.16% (438/275368 alleles). Considering available information, this variant is classified as pathogenic. Pathogenic MVK variants are causative for autosomal recessive hyperimmunoglobulin D syndrome (HIDS, MIM: 260920) and mevalonic aciduria (MIM: 610377). References: Houten SM et al.

Inborn genetic diseases Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsJul 22, 2021The c.1129G>A (p.V377I) alteration is located in exon 11 (coding exon 10) of the MVK gene. This alteration results from a G to A substitution at nucleotide position 1129, causing the valine (V) at amino acid position 377 to be replaced by an isoleucine (I). Based on the available evidence, this variant is pathogenic for mevalonate kinase deficiency (AR); however, it is unlikely to be causative of MVK-related porokeratosis (AD). Based on data from the Genome Aggregation Database (gnomAD), the MVK c.1129G>A alteration was observed in 0.16% (443/280790) of total alleles studied, with a frequency of 0.24% (303/128360) in the European (non-Finnish) subpopulation. This common mutation has been reported in individuals with clinical and biochemical features consistent with mevalonate kinase deficiency in both the homozygous and compound heterozygous state (Cuisset, 2001; Drenth, 1999; Houten, 1999; Munoz, 2019); however, asymptomatic individuals have also been reported (Lainka, 2012; Messer, 2016). Functional studies showed that this alteration results in reduced enzyme activity (Houten, 1999; Messer, 2016). Based on the available evidence, this alteration is classified as pathogenic. -
