IDH1 and IDH2
Purpose: | Activating IDH1 R132 and IDH2 R140 and R172 mutations are seen in gliomas, acute myeloid leukemias, cholangiocarcinomas, and a subset of cartilaginous tumors. In gliomas they are seen in a substantial proportion of low grade tumors; in acute myeloid leukemias they may identify tumors with a poor prognosis. In addition, targeted treatment is being developed for these mutations, which result in altered enzyme activity. |
