| Gene Variant Descriptions | IDH1 R132X indicates any Idh1 missense mutation that results in the replacement of the arginine (R) at amino acid 132 by a different amino acid. R132 variants are hotspot mutations in Idh1, which often results in conversion of alpha-ketoglutarate to the onco-metabolite 2HG (R(-)-2-hydroxyglutarate) (PMID: 19935646, PMID: 28330869, PMID: 21326614). |
