FGFR fusions in the driver's seat.

Through a clinical deep sequencing protocol, Wu and colleagues have identified multiple FGFR fusion proteins in diverse cancers. Pharmacologic inhibition of FGFR suppressed the growth of FGFR fusion-positive tumor models, suggesting that these FGFR fusions are oncogenic drivers and highlighting the use of streamlined clinical sequencing efforts to identify novel, actionable driver oncoproteins in human tumors.
