Epidermal Growth Factor Receptor Activation in Glioblastoma through Novel Missense Mutations in the Extracellular Domain
[Paper-level Aggregated] PMCID: PMC1702556
Evidence Type(s): Predictive
Summary: Mutation: L858R | Summary: The L858R mutation may sensitize transformed cells to EGFR kinase inhibitors, indicating a correlation with response to therapy.
Evidence Type: Predictive Mutation: L861Q | Summary: The L861Q mutation is suggested to sensitize transformed cells to EGFR kinase inhibitors, indicating a potential response to therapy.
Evidence Type: Predictive Mutation: L790M | Summary: The L790M mutation, in combination with L858R, is described as drug-resistant, suggesting a role in therapy resistance to EGFR kinase inhibitors.
Evidence Type: Predictive Mutation: R108K | Summary: The R108K mutation in EGFR was associated with clinical responses to erlotinib in gliomas, suggesting a correlation with treatment sensitivity, and was also identified in gliomas that failed EGFR kinase inhibitor therapy, indicating a possible link to treatment resistance.
