a–c) Case 1, with epidermal growth factor receptor (EGFR) exon 21 mutations (V843I and L858R). a) Pedigree chart. The black case corresponds to the index patient. b) DNA sequencing electrophoretograms for DNA obtained from lung tumour tissue identifying EGFR exon 21 mutations; both mutations are present. c) DNA sequencing electrophoretograms for DNA obtained from blood, identifying one EGFR exon 21 mutation, the V834I variant, is present and confirming it is germ-line. d–f) Case 2, with EGFR exon 21 mutation (P848L). d) Pedigree chart. The black case corresponds to the index patient. The hatched box represents a case with head and neck carcinoma. e) DNA sequencing electrophoretograms for DNA obtained from lung tumour tissue identifying an EGFR exon 21 mutation (P848L). f) DNA sequencing electrophoretograms for DNA obtained from blood identifying the EGFR exon 21 P848L variant is present and confirming it is germ-line.
