      [Paper-level Aggregated] PMCID: PMC1240052

      Evidence Type(s): Functional

      Summary: Mutation: D837A | Summary: The D837A mutation is described as kinase-dead and kinase-inactive, failing to induce colony formation, indicating an alteration in molecular function compared to the wild-type EGFR.

      Evidence Type: Functional Mutation: L858R | Summary: The L858R mutation in EGFR is associated with ligand-independent autophosphorylation, constitutive phosphorylation of Shc, and constitutive activation of STAT signaling pathways, indicating alterations in molecular function related to receptor activation and downstream signaling pathways.

      Evidence Type: Functional Mutation: mutant EGFR | Summary: The mutant EGFR leads to constitutive activation of signaling pathways, indicating an alteration in molecular function related to cell survival.

    3. Oncogenic Transformation by Inhibitor-Sensitive and -Resistant EGFR Mutants

      [Paper-level Aggregated] PMCID: PMC1240052

      Evidence Type(s): Predictive

      Summary: Mutation: G719S | Summary: The G719S mutation is associated with resistance to gefitinib, indicating its predictive value for therapy response in lung adenocarcinoma patients.

      Evidence Type: Predictive Mutation: L747_E749del A750P | Summary: The L747_E749del A750P mutation correlates with sensitivity to gefitinib and erlotinib, supporting its predictive role in therapy response for lung adenocarcinoma.

      Evidence Type: Predictive Mutation: L858R | Summary: The L858R mutation is linked to increased sensitivity to gefitinib and erlotinib, demonstrating its predictive significance for treatment outcomes in lung adenocarcinoma patients. Additionally, it is associated with a response to the irreversible EGFR inhibitor CL-387,785, which shows greater effectiveness compared to gefitinib or erlotinib in inhibiting colony formation and autophosphorylation.
