Gene Variant Descriptions | IDH1 R132H lies within the active site of the Idh1 protein (PMID: 19228619). R132H results in decreased conversion of isocitrate to alpha-ketoglutarate by Idh1, but also confers a gain of function to Idh1, as indicated by increased conversion of alpha-ketoglutarate to the onco-metabolite 2HG (R(-)-2-hydroxyglutarate) in cell culture and in vitro assays, and is associated with increased 2HG levels in patient samples (PMID: 19935646, PMID: 23731180). |
