EGFR pathogenic mutations sensitize in varying degrees to inhibition by small molecule TKIs. These mutations include both class I short in-frame deletions and class II missense mutations. One of these mutations, the L858
[Paragraph-level] PMCID: PMC4823091 Section: RESULTS PassageIndex: 7
Evidence Type(s): Predictive, Diagnostic
Justification: Predictive: The passage states that the L858R mutation sensitizes to inhibition by small molecule TKIs, indicating a correlation with response to therapy. Diagnostic: The L858R mutation is described as having the highest prevalence among activating EGFR kinase domain missense mutations, which suggests its use in defining or classifying a subtype of disease.
