Figure 1 ROS1 rearrangements are generally mutually exclusive with oncogenic driver alterations in EGFR, KRAS, and anaplastic lymphoma receptor tyrosine kinase gene (ALK). One case (patient 53) in the Massachusetts General Hospital cohort had ROS1 testing results that were positive by fluorescence in situ hybridization (FISH) (dark gray) but negative by next-generation sequencing (NGS) (purple). This case was found to harbor a KRAS G13D mutation (red) and an EGFR C781F mutation of unknown significance (blue). Another case (patient 48) had a KRAS I24N mutation of unknown significance (blue). All other ROS1-rearranged NSCLC cases in the Massachusetts General Hospital cohort tested negative (white) for concurrent EGFR and KRAS mutations and ALK rearrangements.
