Abstract Text BRAF V600E is an emerging drug target in lung cancer, but the clinical significance of non-V600 BRAF mutations in lung cancer and other malignancies is less clear. Here, we report the case of a patient with metastatic lung adenocarcinoma with BRAF G469L mutation refractory to vemurafenib. We calculated a structure model of this very rare type of mutated BRAF kinase to explain the molecular mechanism of drug resistance. This information may help to develop effective targeted therapies for cancers with non-V600 BRAF mutations.

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 G469L missense unknown BRAF G469L lies within the protein kinase domain of the Braf protein (UniProt.org). G469L has been identified in the scientific literature (PMID: 24035431, PMID: 26301799, PMID: 26200454), but has not been biochemically characterized and therefore, its effect on Braf protein function is unknown (PubMed, Aug 2024).
