RASA1/NF1-Mutant Lung Cancer: Racing to the Clinic?

Although mutation of NF1 has been described in non-small cell lung cancer (NSCLC), co-mutation with RASA1, another Ras-GTPase activating protein (RasGAP), defines a novel genetically defined subclass of NSCLC. RASA1/NF1-mutant cell lines are highly sensitive to MEK inhibitors, warranting clinical evaluation of MAPK inhibition in this subclass of patients.
