Profile Name BRAF L525R
Gene Variant Detail

BRAF L525R (gain of function - predicted)

Relevant Treatment Approaches

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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 L525R colorectal cancer not predictive Cetuximab Case Reports/Case Series Actionable In a clinical study, Erbitux (cetuximab) treatment as a third-line therapy resulted in stable disease with progression-free survival of 4 months in a patient with metastatic colorectal cancer harboring BRAF L525R (PMID: 31515458). 31515458
BRAF L525R Advanced Solid Tumor sensitive Selumetinib Preclinical - Cell culture Actionable In a preclinical study, Koselugo (selumetinib) inhibited viability of cells expressing BRAF L525R in culture (PMID: 36856908). 36856908
BRAF L525R Advanced Solid Tumor predicted - sensitive Dactolisib + Selumetinib Preclinical - Cell culture Actionable In a preclinical study, the addition of Dactolisib (BEZ235) to treatment with Koselugo (selumetinib) resulted in increased inhibition of proliferation in Koselugo (selumetinib)-resistant cells expressing BRAF L525R compared to Dactolisib (BEZ235) alone (PMID: 36856908). 36856908
BRAF L525R Advanced Solid Tumor sensitive Dactolisib Preclinical - Cell culture Actionable In a preclinical study, Dactolisib (BEZ235) inhibited viability of cells expressing BRAF L525R in culture (PMID: 36856908). 36856908
