Gene FLT3
Variant Y842C
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions FLT3 Y842C lies within the protein kinase domain of the Flt3 protein (UniProt.org). Y842C results in constitutive phosphorylation of Flt3, activation of Stat5 signaling, is transforming in cell culture (PMID: 15345593), and has been demonstrated to promote secondary drug resistance in the context of FLT3 internal tandem duplication (FLT3-ITD) mutations (PMID: 22504184, PMID: 29187377).

Filtering

  • 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"

Sorting

  • 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.

Molecular Profile Indication/Tumor Type Response Type Therapy Name Approval Status Evidence Type Efficacy Evidence References
FLT3 Y842C acute myeloid leukemia sensitive Midostaurin Preclinical - Cell culture Actionable In a preclinical study, Rydapt (midostaurin) induced cell death and inhibited FLT3 activation and downstream STAT5 activation in primary acute myeloid leukemic blasts harboring FLT3 Y842C in culture (PMID: 15345593). 15345593
FLT3 Y842C acute myeloid leukemia resistant Imatinib Preclinical Actionable In a preclinical study, primary AML blasts expressing FLT3 Y842C were resistant to Gleevec (imatinib) as demonstrated by constitutively phosphorylated FLT3 and STAT-5 (PMID: 15345593). 15345593
FLT3 Y842C hematologic cancer sensitive Gilteritinib Preclinical - Cell culture Actionable In a preclinical study, Xospata (gilteritinib) resulted in reduced cell viability in transformed cells expressing FLT3 Y842C in culture (PMID: 32040554). 32040554
