We identified two somatic activating missense mutations affecting FGFR1, including FGFR1 p.K656E and FGFR1 p.V561M. While the former is a known hotspot mutation that is both activating and transforming, the latter has be
[Paragraph-level] PMCID: PMC8077124 Section: ABSTRACT PassageIndex: 7
Evidence Type(s): Oncogenic, Predictive
Justification: Oncogenic: The passage describes p.K656E as a known hotspot mutation that is activating and transforming, indicating its role in tumor development or progression. Predictive: The passage mentions that p.V561M is described as a gatekeeper mutation imparting resistance to FGFR inhibitors, which correlates with treatment response.
