Integrated Genomic Characterization Reveals Novel, Therapeutically Relevant Drug Targets in FGFR and EGFR Pathways in Sporadic Intrahepatic Cholangiocarcinoma
[Paper-level Aggregated] PMCID: PMC3923676
Evidence Type(s): Oncogenic, Predictive
Justification: Oncogenic: The E384X mutation in ERRFI1 is described as a loss of function mutation that leads to nearly complete loss of function, suggesting its role in tumorigenesis by negatively regulating EGFR activation. Predictive: The presence of the E384X mutation in ERRFI1 was associated with rapid and robust disease regression when treated with erlotinib, indicating its potential as a predictive biomarker for response to EGFR inhibitors.
