Pricing Comments

Our favored testing approach is exome based NextGen sequencing with CNV analysis. This will allow cost effective reflexing to PGxome or other exome based tests. However, if full gene Sanger sequencing is desired for STAT turnaround time, insurance, or other reasons, please see link below for Test Code, pricing, and turnaround time information. If the Sanger option is selected, CNV detection may be ordered through Test #600.

An additional 25% charge will be applied to STAT orders. STAT orders are prioritized throughout the testing process.

Turnaround Time

3 weeks on average for standard orders or 2 weeks on average for STAT orders.

Please note: Once the testing process begins, an Estimated Report Date (ERD) range will be displayed in the portal. This is the most accurate prediction of when your report will be complete and may differ from the average TAT published on our website. About 85% of our tests will be reported within or before the ERD range. We will notify you of significant delays or holds which will impact the ERD. Learn more about turnaround times here.

Clinical Features and Genetics

Clinical Features

Hyperimmunoglobulin D syndrome (HIDS) is a disorder characterized by periodic fevers lasting on average 4-6 days and beginning within the first year of life. Fevers may be provoked by vaccination, minor trauma, surgery, or stress and are associated with abdominal pain, rash, nausea, diarrhea, and lymphadenopathy. Symptoms typically resolve following periodic fever bouts, with joint and skin symptoms disappearing slower (Bader-Meunier et al. 2010; Haas and Hoffmann 2006; Houten et al. 1999).

Mevalonate Aciduria (MVA) is another disorder due to mutation in the MVK gene. Symptoms are identical to HIDS, but also include developmental and neurological abnormalities. These symptoms include hyptonia, psychomotor retardation, failure to thrive, ataxia, and congenital malformations such as microcephaly, dolichocephaly, blue sclerae and central cataracts. Currently, biochemical and genetic testing is unable to distinguish between HIDS and MVA with both types having considerable clinical heterogeneity (Bader-Meunier et al. 2010; Haas and Hoffmann 2006; Houten et al. 1999).

Mutations in the MVK gene have recently been shown to be involved in the pathogenesis of disseminated superficial actinic porokeratosis (DSAP) which is characterized by multiple small, annular, anhidrotic, keratotic lesions found on sun-exposed areas of skin. Symptom onset typically occurs during adolescent with complete penetrance for DSAP occurring before the fourth decade of life (Zhang et al. 2012; Lu et al. 2014).


HIDS and MVA are inherited in an autosomal recessive manner through mutations in the MVK gene. To date, missense variants are found in all cases of HIDS and MVA with the c.1129G>A (p.Val377Ile) variant being most prevalent. In two large cohort studies, this variant was found in 34% and 80% of patients (Mandey et al. 2006; Bader-Meunier et al. 2011). Small insertions, deletions, splice site alterations, and nonsense mutations have also been reported but are found in compound heterozygous patients with another missense mutation. Gross deletions encompassing the whole MVK gene have not been reported to date. The MVK gene encodes mevalonate kinase which involved in the isoprenoid biosynthesis pathway and catalyzes mevalonate to 5-phosphomevalonate. While the exact molecular mechanism whereby MVK mutations lead to disease is unclear, it has been suggested that impairment of prenylation chains might play a role (Houten et al. 2002).

In one report, DSAP was described as being inherited in an autosomal dominant manner in Chinese patients via mutations in the MVK gene in both de novo and familial cases. This report documented 14 different mutations which occurred throughout the gene with missense, splice site alterations, small insertions, and small deletions occurring in 68%, 26%, 2%, and 4% cases respectively. The reason why HIDS and MVA carriers have not been reported to display DSAP is unknown. Preliminary studies indicate mevalonate kinase has a role in regulation of calcium induced keratinocyte differentiation and protects cells from ultraviolet induced apoptosis (Zhang et al. 2012).

Clinical Sensitivity - Sequencing with CNV PGxome

Analytical sensitivity is estimated at >99% as no gross deletions have been reported in the MVK gene. In patients with biochemical evidence of impaired mevalonate kinase activity and suspected HIDS or MVA, causative mutations were found in 106 of 106 patients (Mandey et al. 2006). A separate study identified two pathogenic variants in 44 of 50 patients with known HIDS or MVA (Bader-Meunier et al. 2010).

Testing Strategy

This test provides full coverage of all coding exons of the MVK gene plus 10 bases of flanking noncoding DNA in all available transcripts along with other non-coding regions in which pathogenic variants have been identified at PreventionGenetics or reported elsewhere. We define full coverage as >20X NGS reads or Sanger sequencing. PGnome panels typically provide slightly increased coverage over the PGxome equivalent. PGnome sequencing panels have the added benefit of additional analysis and reporting of deep intronic regions (where applicable).

Dependent on the sequencing backbone selected for this testing, discounted reflex testing to any other similar backbone-based test is available (i.e., PGxome panel to whole PGxome; PGnome panel to whole PGnome).

Indications for Test

This test is recommended for individuals with periodic fever syndrome with onset before 5 years of age. Common laboratory findings include elevated white blood cell counts, erythrocyte sedimentation rate, C-reactive protein levels, and levels of mevalonic acid in urine . In >85% of cases patients will have elevated IgD levels but levels may appear normal, especially in times between fever bouts (Bader-Meunier et al. 2010). This test may also be considered for the reproductive partners of individuals who carry pathogenic variants in MVK.
