RESUMO
Childhood acute lymphoblastic leukemia (ALL) is the leading cause of cancer-related deaths among children. Two recent genome-wide association studies and several replicated studies have provided convincing evidence that inherited genetic variation in ARID5B contributes to childhood ALL predisposition. In the present study, we performed a meta-analysis to systematically summarize the association between ARID5B genetic polymorphism and the risk for ALL. We conducted a search of case-control studies on the association of ARID5B genetic polymorphisms with susceptibility to ALL in PubMed, EMBASE, Wanfang database in China, and Chinese National Knowledge Infrastructure databases. Data from eligible studies were extracted for meta-analysis. ALL risk associated with ARID5B genetic polymorphism was estimated by pooled odds ratios (ORs) and 95% confidence intervals (95% CIs). Nine articles including 13 case-control studies were included in the present meta-analysis. We found that rs10821936 polymorphism in ARID5B gene was associated with increased risk for ALL (P < 0.0001; OR = 1.27; 95%CI, 1.17-1.37). This meta-analysis suggests that ARID5B genetic polymorphism was associated with the increased risk of ALL.
