Thus, we conducted a correlation study between FGF11 and EGFR (19DEL, L858R), EGFR (Exon 20ins), KRAS (G12C), ALK, ROS1, BRAF, NTRK1/2/3, MET, and RET, which are all recommended by the NCCN guidelines for the diagnosis of nonsmall cell lung cancer. The gene discussed is BRAF; the disease is lung cancer.
