Profile Name BRAF L597Q
Gene Variant Detail

BRAF L597Q (gain of function)

Relevant Treatment Approaches MEK inhibitor (Pan) MEK1 Inhibitor MEK2 Inhibitor LY3009120

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.

BRAF L597Q Advanced Solid Tumor resistant Vemurafenib Preclinical - Cell culture Actionable In a preclinical study, Zelboraf (vemurafenib) did not inhibit MEK and ERK activation in transformed cells over expressing the constitutively dimerized BRAF L597Q (PMID: 26343582). 26343582
BRAF L597Q Advanced Solid Tumor resistant Vemurafenib Clinical Study - Cohort Actionable In a Phase II trial (MyPathway), Zelboraf (vemurafenib) treatment resulted in an objective response in only 4% (1/23) of patient with advanced solid tumors harboring non-V600 BRAF mutations, 1 of the non-responding patients harbored BRAF L597Q (PMID: 29320312; NCT02091141). 29320312
