Cases showing discrepant results between standard methods and the Idylla EGFR Mutation Assay
| ID sample | Reference methods | Idylla EGFR Mutation Assay | NGS analysis |
| 9 | WT | p.G719X | p.G719A |
| 25 | WT | p.G719X | p.G719A |
These cases harboured a mutation in exon 18, which was detected by the Idylla method and confirmed by next-generation sequencing (NGS); such mutation was however missed by the reference methods that targeted only exon 19 and exon 21.
WT, wild-type.
