Among the many patient-specific pathways were “Rho GTPase activate protein kinases (PKNs)” and “PI3K/Akt signaling in cancer” (in patient ID 111); “mTOR signaling” as well as “signaling by ERBB4 or PTK6” (in patient ID 129); “TLR4 cascade” and “G alpha signaling events” (in patient ID 110); “signaling by BRAF and RAF fusion” as well as “RHO GTPases activate IQGAPs” (in patient ID 101). The gene discussed is ERBB4; the disease is cancer.
