We also investigated whether drug efficacy is dependent on the FGFR variants in patients. For this purpose, we retrospectively collected variant information and drug efficacy data related to FGFR inhibitors in 399 cases
[Paragraph-level] PMCID: PMC8285406 Section: RESULTS PassageIndex: 22
Evidence Type(s): Predictive, Oncogenic
Justification: Predictive: The passage discusses the correlation between the FGFR3 S249C variant and the response to treatment with FGFR TKIs, indicating that patients with this mutation exhibited partial or complete responses, which aligns with predictive evidence. Oncogenic: The FGFR3 S249C variant is described as the most frequent mutation of FGFR3, suggesting its role in tumor development or progression, which supports its classification as oncogenic.
