Abstract

(R)-2-hydroxyglutarate (R-2-hg) has gained significant interest as a circulating biomarker for patients with cancers that harbor mutations in the isocitrate dehydrogenase (IDH) gene. R-2-hg detection is challenging as it must be separated from its enantiomer, (S)-2-hydroxyglutarate (S-2-hg). Here, we present a novel gas chromatography–tandem mass spectrometry method (GC-MS/MS) assay that can be used to separate and detect 2-hg enantiomers for clinical use.
