Gene Symbol TET2
Synonyms IMD75 | KIAA1546 | MDS
Gene Description TET2, methylcytosine dioxygenase TET2, is a member of the ten-eleven-translocation family of genes that plays a role in DNA methylation and is involved in hematopoesis (PMID: 26099018, PMID: 25510268, PMID: 27848178). TET2 has been identified as a tumor suppressor in hematological malignancies, and mutations in TET2 are common in hematological cancers including myelodysplastic syndrome, chronic myelomoncytic leukemia, and atypical CML (PMID: 26099018, PMID: 22240200, PMID: 30138727) and epigenetic dysregulation has been observed in glioblastoma (PMID: 29899831).


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"


  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

TET2 T1063Nfs*5 TET2 E1207K angioimmunoblastic T-cell lymphoma predicted - sensitive Dasatinib Case Reports/Case Series Actionable In a Phase I trial, four patients with relapsed/refractory angioimmunoblastic T-cell lymphoma harboring TET2 mutations and/or RHOA G17V achieved a partial response within 30 days of Sprycel (dasatinib) treatment, including one patient harboring TET2 T1063Nfs*5 and TET2 E1207K who maintained the partial response at the time of trial discontinuation (PMID: 32107212). 32107212
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
