MET and breast cancer: There are also new actionable mutations on the horizon that are not well described in breast cancer with developing targeted therapies, including mutated genes such as dynein (hsp90 inhibitors, HDAC inhibitors), MST1 (anti-MST1 receptor antibodies), ROS-1 (inhibitors), HGF (antibodies against c-met, c-met inhibitors), and ALDH8A1 (disulfiram).
