Predicted shared pathways among fusion proteins in lipofibromatosis. The detected fusions involved either ligands (EGF, HBEGF, TGFA) to the EGF receptor (EGFR), EGFR itself, or other receptor tyrosine kinases (ROS1, RET, PDGFRB) that all are known to activate the PI3K–AKT–mTOR pathway. The black boxes indicate the kinase domains. Also the two proteins involved in the EGR1-GRIA1 fusion have been implicated in EGFR signaling
