Gene BRAF
Variant G464V
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions BRAF G464V (also reported as G463V) lies within the protein kinase domain of the Braf protein (UniProt.org). G464V results in increased Braf kinase activity and increased downstream Mek and Erk activation (PMID: 12068308, PMID: 26343582), and in one of two cell lines, increased cell proliferation and viability compared to wild-type Braf in culture (PMID: 29533785).

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
BRAF G464V 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, 2 of the non-responding patients harbored BRAF G464V (PMID: 29320312; NCT02091141). 29320312
BRAF G464V 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 G464V (PMID: 26343582). 26343582
BRAF G464V lung adenocarcinoma no benefit Trametinib Case Reports/Case Series Actionable In a Phase II trial (NCI-MATCH), Mekinist (trametinib) treatment did not demonstrate clinical activity in patients with advanced solid tumors or lymphoma harboring BRAF fusion or non-V600 mutations, resulted in progressive disease in a patient with lung adenocarcinoma harboring BRAF G464V (PMID: 31924734; NCT02465060). 31924734
