On the other hand, the genomic alteration/mutation analysis of the hub-DEGs reflected that most mutation for the EGFR occurred across the four lung cancer studies and was followed by the MYC and CHEK1 genes, since EGFR is a highly mutant/altered gene for lung cancer and NSCLC as well [79]. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
