Germ Cell Tumor
Activation of FGFR protein family can lead to the activation of RAS-MAPK and PI3K-AKT pathways. Amplification of FGFR2 has been observed in lung adenocarcinoma, lung squamous cell carcinoma, endometrial carcinoma, urothelial carcinoma, germ cell tumor and breast cancers. Anti-FGFR2 agents are actively under multiple clinical trials against many types of solid tumor, including lung squamous cell carcinoma, gastric cancer, endometrial cancer, and cholangiocarcinoma. Germeline mutations in FGFR2 are also associated with multiple craniosynostosis syndromes.
