EGFR Exon 21 Mutation

This is the original ClinicalTrials.gov condition label, found in 4 distinct published trials. It is kept separate from a MONDO disease identifier until a specific normalization is supported. Related interventions are co-recorded in studies; they are not medical recommendations.

Data basis: current published ClinicalTrials.gov records and, where present, RxNorm, MONDO and FDA-label identifiers. See the evidence interpretation and counting methodology.
