FGFR1 (fibroblast growth factor receptor type 1) encodes the fibroblast growth factor receptor type 1 protein, a receptor tyrosine kinase. FGFR1 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 FGFR1 has been reported in many cancers, including oral squamous cell carcinoma (PMID: 16807070), breast cancer (PMID: 20179196), esophageal squamous cell carcinoma (PMID: 12147242), ovarian cancer (PMID: 17699850), bladder cancer (PMID: 11389083), prostate cancer (PMID: 14614009), and lung cancer, predominantly in the squamous subtype (PMID: 21666749; PMID: 17982442; PMID: 21160078).

FGFR1 is altered in 3.27% of all cancers with breast carcinoma, non-small cell lung carcinoma, colorectal adenocarcinoma, malignant glioma, and ovarian neoplasm having the greatest prevalence of alterations [3].

FGFR1 GENIE Cases - Top Diseases

The most common alterations in FGFR1 are FGFR1 Amplification (2.25%), FGFR1 Mutation (1.63%), FGFR1 Loss (0.29%), FGFR1 N546K (0.12%), and FGFR1 D127Mfs*25 (0.10%) [3].
