Summary Summary

Mevalonic aciduria is the severe form of mevalonate kinase deficiency, a condition characterized by recurrent episodes of fever that typically begin during infancy.^[1] During these fever episodes, people with mevalonic aciduria may have an enlarged liver and spleen (hepatosplenomegaly), lymphadenopathy, abdominal pain, diarrhea, joint pain (arthralgia), and skin rashes. Additional ongoing issues include developmental delay, progressive ataxia, progressive problems with vision, an unusually small, elongated head, and failure to thrive.^[1]^[2] Mevalonic aciduria is caused by deficiency of mevalonate kinase, the first committed enzyme of cholesterol biosynthesis.^[2] This deficiency occurs as a result of inherited mutations in the MVK gene.^[1]^[2] This condition is inherited in an autosomal recessive pattern.^[1] Treatment is challenging and remains mainly supportive.^[2]

The less severe type of mevalonate kinase deficiency is called hyperimmunoglobulinemia D syndrome (HIDS).^[1]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Treatment Treatment

Treatment of mevalonic aciduria remains a challenge.^[3] There is no standard treatment that is effective in all patients, so it remains mainly supportive.^[2] Treatment with simvastatin (an inhibitor of hydroxymethylglutaryl coenzyme A reductase, the enzyme that catalyzes the formation of mevalonic acid), which has been used with guarded success in patients with HIDS, worsened the clinical status of two patients with mevalonic aciduria.^[4] Anakinra, another medication used with some degree of success in HIDS patients, induced partial remission in at least one patient with mevalonic aciduria, but not all patients respond to so favorably.^[3]

Reports of successful treatment of mevalonic aciduria through allogenic bone marrow transplantation have also surfaced. At this point, this therapy is investigational and potentially applicable to patients with mevalonic aciduria whose condition is resistant to therapy with anti-inflammatory drugs (e.g., inhibitors of TNF-alpha and interleukin-1 beta).^[4]^[5]

The following articles provide additional details regarding treatment of mevalonic aciduria.
