Abstract

Mutations in isocitrate dehydrogenase (IDH) 1 and 2, originally discovered in 2008, occur in the vast majority of low-grade gliomas and secondary high-grade gliomas. These mutations, which occur early in gliomagenesis, change the function of the enzymes, causing them to produce 2-hydroxyglutarate, a possible oncometabolite, and to not produce NADPH. IDH mutations are oncogenic, although whether the mechanism is through alterations in hydroxylases, redox potential, cellular metabolism, or gene expression is not clear. The mutations also drive increased methylation in gliomas. Gliomas with mutated IDH1 and IDH2 have improved prognosis compared with gliomas with wild-type IDH. Mutated IDH can now be detected by immunohistochemistry and magnetic resonance spectroscopy. No drugs currently target mutated IDH, although this remains an area of active research.

  • IDH1 and IDH2 mutations identified in low-grade glioma, chondrosarcoma, cholangiocarcinoma, and AML.

    “IDH1 and IDH2 mutations have been identified in low-grade glioma, where they represent a likely initiator lesion, as well as in chondrosarcoma, cholangiocarcinoma, and acute myeloid leukemia (AML) (Balss et al., 2008; Borger et al., 2012; Cohen et al., 2013; Mardis et al., 2009; Parsons et al., 2008; Paschka et al., 2010).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
