title: Role of isocitrate dehydrogenase in glioma.
abstract: Recently, the isocitrate dehydrogenase (IDH) enzymes have become a focal point for research aimed at understanding the biology of glioma and identifying novel targets for therapy. Following the publication of a landmark genetic sequencing study in 2008, which identified IDH1 as a frequently mutated gene in glioblastoma, much work has been carried out to further characterize the frequency, associations and clinical implications of IDH1/2 mutations. Mutations in IDH genes are thought to occur early in tumorigenesis and define a subgroup of glioma that are characterized by specific metabolic changes and improved prognosis. At present, assays identifying tumors with IDH1 mutations are clinically useful as prognostic markers. While the mechanisms linking IDH1/2 mutations to tumor development are still under investigation, the cellular milieu created by these mutations offers potential targets for the development of novel therapeutics.
