Mevalonate kinase deficiency (MKD) is a rare autosomal recessive metabolic disorder caused by mutations in the MVK gene. It leads to a broad phenotypic spectrum‚ including autoinflammatory symptoms and neurological abnormalities. The deficiency disrupts the biosynthesis of cholesterol and isoprenoids‚ causing recurrent episodes of fever‚ joint pain‚ and muscle pain. Diagnosis involves genetic testing to identify pathogenic variants in the MVK gene. Treatment options include IL-1 blockade therapy with canakinumab‚ although access to costly treatments can be challenging for patients.
Overview of Mevalonate Kinase Deficiency
Mevalonate kinase deficiency is a rare autosomal recessive metabolic disorder linked to mutations in the MVK gene. It leads to disrupted cholesterol and isoprenoid synthesis‚ resulting in episodes of fever‚ joint pain‚ muscle pain‚ and other related symptoms. Genetic testing is imperative for diagnosis‚ with treatment often involving IL-1 blockade therapy with canakinumab.
Role of Mevalonate Kinase in Isoprenoid and Sterol Synthesis
Mevalonate kinase plays a crucial role as an early enzyme in isoprenoid and sterol synthesis‚ being the second enzyme in the Mevalonate pathway. A deficiency in mevalonate kinase activity‚ attributed to MVK gene mutations‚ disrupts the production of Mevalonate-5-phosphate‚ impacting the synthesis of cholesterol and isoprenoids. This disruption leads to the characteristic symptoms of Mevalonate Kinase Deficiency‚ such as recurrent episodes of fever‚ joint pain‚ muscle pain‚ and other associated manifestations.
MVK Gene Mutations and Pathogenic Variants
Mevalonate kinase deficiency (MKD) arises from mutations in the MVK gene‚ resulting in pathogenic variants known to cause this autosomal recessive metabolic disorder. These genetic alterations underlie the disruption in isoprenoid and sterol synthesis‚ leading to the diverse clinical manifestations associated with MKD‚ including recurrent fever episodes and other inflammatory symptoms that characterize the condition.
