  • Patent number: 9487815
    Abstract: The present invention relates to a method for detecting (D)-2-hydroxyglutarate or (D)-2-hydroxyadipic acid in a sample, the method comprising the steps of: a) contacting a sample with a reagent mixture, wherein said reagent mixture comprises: (i) a solvent, (ii) a dye having an oxidized state and a reduced state, wherein the reduced state can be distinguished from the oxidized state and wherein the dye is initially present in the oxidized state, (iii) an electron transfer agent, (iv) a (D)-2-hydroxyglutarate dehydrogenase enzyme, and (v) a cofactor; and b) detecting (D)-2-hydroxyglutarate or (D)-2-hydroxyadipic acid by measuring the production of the reduced state of the dye. The invention further pertains to a method for diagnosing and/or monitoring a (D)-2-hydroxy-glutarate-associated disease in a subject. Encompassed by the invention is also a method for diagnosing a mutation in an isocitrate dehydrogenase (IDH) gene or in a (D)-2-hydroxyglutarate (D2HG) dehydrogenase enzyme gene in a subject.
