For instance, non-small-cell lung cancer requires the presence of EGFR, ALK, ROS1, BRAF, MET, RET, and KRAS genes [6], while the prognosis of colorectal cancer patients can be determined by the mutation of KRAS, NRAS, BRAF, and HER2 genes, as well as microsatellite instability analysis [7,8]. Here, BRAF is linked to colorectal cancer.
