A Catalog of 5’ Fusion Partners in ROS1-Positive NSCLC Circa 2020

ROS1 fusion–positive (ROS1+) NSCLC was discovered in 2007, the same year as the discovery of ALK-positive (ALK+) NSCLC but has trailed ALK+ NSCLC in terms of development. There seems to be a differential response to ROS1 inhibitors, which depend on fusion partners (CD74, SLC34A2, or SDC4); thus, knowledge of the fusion partners in ROS1+ NSCLC is important. To date (end of February 2020), we have identified 24 unique 5’ fusion partners of ROS1 in ROS1+ NSCLC from published literature and congress proceedings. Thus, we published this catalog for easy reference.
