Abstract

2-Hydroxyglutarate (2-HG) is a potential oncometabolite involved in gliomagenesis that has been identified as an aberrant product of isocitrate dehydrogenase (IDH)-mutated glial tumors. Recent genomics studies have shown that heterozygous mutation of IDH genes 1 and 2, present in up to 86% of grade II gliomas, is associated with a favorable outcome. Two reports in this issue describe both ex vivo and in vivo methods that could noninvasively detect the presence of 2-HG in glioma patients. This approach could have valuable implications for diagnosis, prognosis, and stratification of brain tumors, as well as for monitoring of treatment in glioma patients.
