Cleft lip and palate transmembrane protein 1 rs31489 polymorphism is associated with lung cancer risk: a meta-analysis

Research Article

Abstract

The potentially functional polymorphism, rs31489, in the promoter region of cleft lip and palate transmembrane protein 1 (CLPTM1L) gene has been implicated in cancer risk. However, individual published studies showed inconclusive results. To obtain a more precise estimate of the association between CLPTM1L rs31489 and risk of lung cancer, we performed a meta-analysis. Summary odds ratios (ORs) and corresponding 95 % confidence intervals (CIs) were estimated using random-effects models. Ten individual case–control studies in eight publications with 20,680 cases and 28,330 controls were included. Overall, the variant genotypes were associated with a significantly increased lung cancer risk in different genetic models (CC + AC vs. AA: OR = 1.20, 95 % CI 1.12–1.28, P < 0.001; CC vs. AC + AA: OR = 1.15, 95 % CI 1.07–1.23, P < 0.001; CC vs. AA: OR = 1.28, 95 % CI 1.17–1.41, P < 0.001; CC vs. AC: OR = 1.11, 95 % CI 1.05–1.17, P < 0.001; C vs. A: OR = 1.12, 95 % CI 1.06–1.18, P < 0.001). In the stratified analyses, the increased lung risk remained for the studies of Caucasian populations. In conclusion, this meta-analysis suggested that CLPTM1L rs31489 was a potential biomarker for lung cancer risk in Caucasians.
