FGFR2 (fibroblast growth factor receptor 2 gene) encodes the fibroblast growth factor receptor 2 protein, a receptor tyrosine kinase. FGFR2 and other FGFR TKs play crucial roles in development and have been shown in cancers to be deregulated by amplification, point mutation, or translocation (PMID: 20094046). Amplification or activation of FGFR2 has been reported in breast cancer and gastric cancer (PMID: 22731805). FGFR2 mutations have been observed in endometrial cancer and breast cancer (PMID: 18552176; PMID: 22731805; PMID: 23527311).


FGFR2 is altered in 2.02% of all cancers with uterine corpus neoplasm, melanoma, breast carcinoma, colorectal adenocarcinoma, and non-small cell lung carcinoma having the greatest prevalence of alterations [3].

FGFR2 GENIE Cases - Top Diseases

The most common alterations in FGFR2 are FGFR2 Mutation (1.99%), FGFR2 Amplification (0.34%), FGFR2 S252W (0.17%), FGFR2 N549K (0.09%), and FGFR2 C382R (0.09%) [3].
