Fig. 1From: EGFR C797S mutation mediates resistance to third-generation inhibitors in T790M-positive non-small cell lung cancerClonal evolution of NSCLC cancer cells and mechanisms of resistance to third-generation EGFR tyrosine kinase inhibitors. The T790M and C797S mutations were highlighted in the EGFR sequence. Each colored ball represents a distinct clone. The number of balls in each group indicates relative clonal size.
