DAB2IP and lung cancer: In this hospital-based case-control study including 1056 lung cancer patients and 1056 sex and age frequency-matched genetic unrelated cancer-free controls, we genotyped two common polymorphisms in DAB2IP gene (−1420T>G, rs7042542, in promoter region; 97906C>A, rs1571801, in intron 1) and investigated their association with the risk of lung cancer.
