Tier 2InterpretationBRAF is a member of the RAF-family of kinases which plays an important role in the RAS-RAF-MEK-ERK mitotic signaling pathway. The hotspot for mutations in BRAF is at codon Val600 and these are activating mutations. The most common activating mutation is p.Val600Glu(V600E). Activating BRAF(V600E) (Val600Glu) mutations have been identified in approximately 1-2% of lung adenocarcinomas. Various BRAF inhibitors (Vemurafenib, Dabrafenib, and Trametinib) have been FDA approved for therapy for some tumor types in certain clinical settings. Of note, Dabrafenib and Trametinib are approved for metastatic non-small cell lung cancer (NSCLC) harboring BRAF V600E mutations.
