Gene | TET2 |
Variant | G1861R |
Impact List | missense |
Protein Effect | loss of function |
Gene Variant Descriptions | TET2 G1861R lies within the catalytic domain of the Tet2 protein (PMID: 24315485). G1861R confers a loss of function to the Tet2 protein as demonstrated by the inability of G1861R to inhibit cell proliferation, lack of WT1 binding and regulation of WT1 target genes, and reduced enzymatic conversion of 5mC in culture (PMID: 25601757). |

TET2 mutant | acute myeloid leukemia | sensitive | Olaparib | Preclinical - Patient cell culture | Actionable | In a preclinical study, Lynparza (olaparib) treatment inhibited colony formation in patient-derived acute myeloid leukemia cells harboring a TET2 mutation along with FLT3-ITD and NPM1 mutation in culture (PMID: 34215619). | 34215619 |

TET2 mutant | acute myeloid leukemia | predicted - sensitive | Azacitidine | Phase I | Actionable | In a retrospective analysis, presence of a TET2 mutation correlated with higher overall response rate (ORR) in patients with myelodysplastic syndrome and acute myeloid leukemia following treatment with Vidaza (azacitidine), with an ORR of 85% (11/3) in TET2-mutated patients, compared to 47% (34/47) in patients with wild-type TET2, but did not correlate with overall survival (PMID: 21494260). | 21494260 |
TET2 mutant | acute myeloid leukemia | not applicable | N/A | Clinical Study | Prognostic | In multiple clinical studies, including a meta-analysis, TET2 mutations were associated with shorter overall survival in patients with acute myeloid leukemia (PMID: 24524305, PMID: 25412851, PMID: 24994606). | 24524305 25412851 24994606 |
