Profile Name KIT M552_V559del
Gene Variant Detail

KIT M552_V559del (gain of function - predicted)

Relevant Treatment Approaches KIT Inhibitor


  • 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.

KIT P551I KIT M552_V559del gastrointestinal stromal tumor predicted - sensitive Imatinib Case Reports/Case Series Actionable In a clinical case study, Gleevec (imatinib) treatment led to a partial response in a patient with gastrointestinal stromal tumors harboring KIT M552_V559del and KIT P551I, with a progression-free survival of 9 months and an overall survival of 19.5 months (PMID: 18294292). 18294292
KIT P551I KIT M552_V559del KIT Y823D gastrointestinal stromal tumor predicted - resistant Imatinib Case Reports/Case Series Actionable In a clinical case study, a patient with gastrointestinal stromal tumor harboring KIT M552_V559del and KIT P551I progressed following an initial response to Gleevec (imatinib), and was found to have acquired the secondary resistance mutation KIT Y823D (PMID: 18294292). 18294292
