Besides p.T790M, the pathogenic germline EGFR exon20 p.R776H and p.V769M identified in our cohort have also been reported in sporadic lung cancer cases (23, 24); whereas pathogenic germline mutations MET exon16 p.H1094R, RET exon14 p.V804M and p.V804L, and likely pathogenic EGFR exon20 p.G719D are reported in lung cancer for the first time. The gene discussed is EGFR; the disease is lung carcinoma.
