P-Loop/αC-Helix Compressing Mutations and Exon 20 Insertions in EGFR-Mutant NSCLC: A Rapidly Evolving Therapeutic Landscape.
PURPOSE A structure-function classification has defined epidermal growth factor receptor (EGFR) P-loop/αC-helix compressing (PACC) mutations and exon 20 insertions (ex20ins) as distinct subsets of kinase domain EGFR alterations. Lung cancers harboring those mutations display reduced sensitivity to EGFR tyrosine kinase...
