| Gene Variant Descriptions | IDH1 R132C lies within the active site of the Idh1 protein (PMID: 19228619). R132C confers a gain of function to Idh1 as indicated by conversion of alpha-ketoglutarate to the onco-metabolite 2HG (R(-)-2-hydroxyglutarate in culture (PMID: 19935646, PMID: 26161668, PMID: 22885298). |
