Profile Name BRAF G469V
Gene Variant Detail

BRAF G469V (gain of function)

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

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 G469V lung non-small cell carcinoma predicted - sensitive Sorafenib Case Reports/Case Series Actionable In a clinical case study, a patient with synchronous BRAF wild-type hepatocellular carcinoma (HCC) and non-small cell lung cancer harboring BRAF G469V demonstrated a partial response in primary lung lesions, complete response in the lung metastasis, and stability of the HCC following treatment with Nexavar (sorafenib) (PMID: 27388325). 27388325
BRAF G469V melanoma no benefit Encorafenib Preclinical - Cell culture Actionable In a preclinical study, Braftovi (encorafenib) did not inhibit ERK phosphorylation or proliferation of a melanoma cell line harboring BRAF G469V (PMID: 29903896). 29903896
BRAF G469V lung non-small cell carcinoma no benefit Vemurafenib Case Reports/Case Series Actionable In a Phase II trial, Zelboraf (vemurafenib) treatment did not result in response in the cohort of 15 non-small cell lung cancer patients with non-V600 BRAF mutations, which included 1 patient harboring BRAF G469V, and enrollment in this cohort was discontinued (PMID: 31959346; NCT02304809). 31959346
