BRAF and melanoma: Oncology is the frontier of Precision Medicine and typically focus is on identification of gene fusions (e.g. crizotinib, an ALK inhibitor for ALK fusion proteins in lung cancer), mutations (as in the case of vemurafinib, a BRAF inhibitor for melanoma patients with the BRAF V600E mutation) and protein over- expression (e.g. Trastuzumab a HER2-targeted antibody for breast cancer).
