Decreased risk of developing lung cancer in subjects carrying the CLPTM1L rs401681 (G>A) polymorphism: evidence from a meta-analysis
2014
A genome-wide association study revealed that a single nucleotide polymorphism, CLPTM1L - rs401681 (G>A), located at the 5p15.33 locus was significantly associated with increased risk of various cancers; however, its association with lung cancer is currently inconclusive. In order to explore the relationship between this polymorphism and lung cancer risk more precisely, we performed a meta-analysis of eight eligible studies involving 9935 cases and 11,261 controls. The pooled odds ratio (OR) and the 95% confidence interval (CI) were calculated using a fixed- or random-effect models. Results indicated that this polymorphism was significantly associated with lung cancer risk in all genetic models ( GA vs GG: OR = 0.88, 95%CI = 0.83-0.94; AA vs GG: OR = 0.81, 95%CI = 0.70-0.93; AA/GA vs GG: OR = 0.86, 95%CI = 0.81-0.91; AA vs GA/GG:
