A substantial proportion of cancer driver genes (CDG) are also cancer predisposition genes. However, the associations between genetic variants in lung CDGs and the susceptibility to lung cancer have rarely been investigated. We selected expression-related single-nucleotide polymorphisms (eSNP) and nonsynonymous variants of lung CDGs, and tested their associations with lung cancer risk in two large-scale genome-wide association studies (20,871 cases and 15,971 controls of European descent). Conditional and joint association analysis was performed to identify independent risk variants. The associations of independent risk variants with somatic alterations in lung CDGs or recurrently altered pathways were investigated using data from The Cancer Genome Atlas (TCGA) project. We identified seven independent SNPs in five lung CDGs that were consistently associated with lung cancer risk in discovery ( < 0.001) and validation ( < 0.05) stages. Among these loci, rs78062588 in (1q21.3) was a new lung cancer susceptibility locus (OR = 0.86, = 1.65 × 10 ). Subgroup analysis by histologic types further identified nine lung CDGs. Analysis of somatic alterations found that in lung adenocarcinomas, rs78062588C allele ( in 1q21.3) was associated with elevated somatic copy number of (OR = 1.16, = 0.02). In lung adenocarcinomas, rs1611182 ( in 6p22.1) was associated with truncation mutations of the transcriptional misregulation in cancer pathway (OR = 0.66, = 1.76 × 10 ). Genetic variants can regulate functions of lung CDGs and influence lung cancer susceptibility. Our findings might help unravel biological mechanisms underlying lung cancer susceptibility.
