Inherited variation at chromosome 12p13.33, including RAD52, influences the risk of squamous cell lung carcinoma.

ABSTRACT:

Unlabelled

Although lung cancer is largely caused by tobacco smoking, inherited genetic factors play a role in its etiology. Genome-wide association studies in Europeans have only robustly demonstrated 3 polymorphic variations that influence the risk of lung cancer. Tumor heterogeneity may have hampered the detection of association signal when all lung cancer subtypes were analyzed together. In a genome-wide association study of 5,355 European ever-smoker lung cancer patients and 4,344 smoking control subjects, we conducted a pathway-based analysis in lung cancer histologic subtypes with 19,082 single-nucleotide polymorphisms mapping to 917 genes in the HuGE-defined "inflammation" pathway. We identified a susceptibility locus for squamous cell lung carcinoma at 12p13.33 (RAD52, rs6
