Genetic association between AGPHD1 variant and lung cancer risk.

The knowledge of molecular mechanism that underlies the genetic predisposition to lung cancer is yet limited. Results from previous studies addressing the association of AGPHD1 variant rs8034191 with lung carcinogenesis remain inconclusive. Herein, we combined these data and re-examined the association. We performed a meta-analysis of Asian studies identified through various ways. Using the data collected from each eligible study, we combined the effect estimates (ORs and its 95 % CIs) with the fixed effects model (Mantel-Haenszel method). Statistical analyses were done using software. Data from nine studies (29,290 subjects) carried out in Asian populations were analyzed in this work. There was no overall association between variant rs8034191 and lung cancer risk under the allele frequency model (OR = 1.03, 95 % CI = 0.93-1.13, P heterogeneity = 0.522). We observed the same associations under other genetic models and in the subgroup analyses by ethnicity and smoking status. Our results indicate that variant rs8034191 in the AGPHD1 gene may not modify the genetic risk of lung cancer in Asian populations.
