Fibroblast growth factor 19 (FGF19) is a gene that encodes a protein with mitogenic activity that functions as a FGF4 heparin dependent ligand. Missense and silent mutations are observed in cancers such as esophageal cancer, intestinal cancer, and skin cancer.

FGF19 is altered in 4.07% of all cancers with breast invasive ductal carcinoma, invasive breast carcinoma, breast invasive lobular carcinoma, bladder urothelial carcinoma, and lung adenocarcinoma having the greatest prevalence of alterations [3].
