Mutations previously correlated with response were detected in five tumours, four with exon 19 deletions and one with an exon 21 missense L858R point mutation. Increased gene copy number was observed in thirteen tumours,
[Paragraph-level] PMCID: PMC1952070 Section: ABSTRACT PassageIndex: 6
Evidence Type(s): Predictive, Diagnostic
Justification: Predictive: The passage discusses mutations, including the L858R point mutation, in the context of their correlation with response to treatment, indicating a predictive relationship. Diagnostic: The mention of the L858R mutation as part of a group of mutations previously correlated with response suggests its role in defining or classifying a disease subtype.
