The fibroblast growth factor receptor 3 (FGFR3) gene encodes one member of the FGF receptor tyrosine kinase family, which includes four kinases: FGFR1, FGFR2, FGFR3, and FGFR4. FGFRs are involved in downstream signaling via the MAP kinase, JAK/STAT, and PI3K/AKT pathways. FGFR3 gene aberrations have been reported in urothelial, breast, head and neck, lung, brain, gastric, pancreatic, colorectal, kidney, endometrial, ovarian, and cervical cancers and are known to be highly prevalent in bladder cancers.

FGFR3 is altered in 2.53% of all cancers with bladder carcinoma, colorectal adenocarcinoma, non-small cell lung carcinoma, breast carcinoma, and melanoma having the greatest prevalence of alterations [3].

FGFR3 GENIE Cases - Top Diseases

The most common alterations in FGFR3 are FGFR3 Mutation (2.67%), FGFR3 S249C (0.54%), FGFR3 Amplification (0.31%), FGFR3 R248C (0.14%), and FGFR3 Loss (0.13%) [3].
