Moreover, seven novel partners were identified in two retroperitoneal neoplasm patients (FRK-ROS1 and VGLL2-ROS1), one gastric cancer patient (ARHGEF11-ROS1), one liver cancer patient (REV3L-ROS1), one liposarcoma patient (EPHA7-ROS1), one patient with epithelioid hemangioendothelioma (NOTCH1-ROS1), and one squamous cell carcinoma patient (CARD11-ROS1). This evidence concerns the gene ARHGEF11 and epithelioid hemangioendothelioma.
