Methods: A hospital based case-control study in Shehong and Xuzhou centers was performed to evaluate the potential association of the indel polymorphism rs145204276 within GAS5 with CSCC risk, and further in vivo and in vitro assays were applied to confirm the plausible association. Results: When taking ins/ins genotype as reference in codominant model, ins/del genotype confers a slightly increased risk for CSCC [odds ratio (OR) =1.27, 95% confidence interval (CI): 1.04–1.52, P=0.02], the homozygous del/del genotype shows an increased risk for CSCC (OR =2.24, 95% CI: 1.60–2.97, P trend in vivo and in vitro , and stratified analysis has revealed that the relation is more marked in subjects with postmenopausal status, tobacco consumption, or senior age (>49 years). Furthermore, the association of the polymorphism with CSCC risk is salient in cases with tumor stage IV (P=0.001). Conclusions: We have found that the novel functional indel polymorphism rs145204276 is associated with CSCC risk. Replication investigations and further functional assays are required for the current investigation. UR - https://tcr.amegroups.org/article/view/12897
