Answer:
P53, EGFR and KRAS genes
Explanation:
Mutations on somatic cells will disturbs the cell cycle and induce cell proliferation which lately results in tumour formation. The mutated P53, EGFR and KRAS genes causes lung cancer. P53 has direct contact with DNA acts a suppressor of tumour and guards the cell divisions. When these genes are mutated they induce expression of different genes (especially P53) leading to lung cancer.
