Additionally, FGFR2-fused proteins have been identified in intrahepatic cholangiocarcinomas, lung, thyroid and prostate cancers; that is, FGFR2/citron Rho-interacting kinase, FGFR2/coiled-coil domain-containing protein 6, FGFR2/cell cycle and apoptosis regulator protein 2 and FGFR2/oral-facial-digital syndrome 1 protein [45]. This evidence concerns the gene FGFR2 and prostate cancer.
