Evidence Type(s): Predictive, Diagnostic
Justification: Predictive: The passage discusses the correlation between the G770 variant and radiographic responses to therapies (poziotinib and mobocertinib) in advanced lung cancers, indicating its predictive nature regarding treatment response. Diagnostic: The mention of "EGFR exon 20 insertion mutations with G770 equivalence" suggests that the G770 variant is used to classify or define a specific subtype of lung cancer, supporting its role as a diagnostic marker.
