We found PROM1 mutation in 3 pairs of lung cancers and normal tissues, including 1 SCC and 2 ADCs with mutation frequency being 1.5% and CRTC2 mutation in 5 pairs of lung cancers and normal tissues, including 3 ADCs and 2 SCCs with mutation frequency being 2.5%. This evidence concerns the gene CRTC2 and lung carcinoma.
