Abstract

Previous studies have found inconsistent results regarding gene deletion in APOBEC3 (apolipoprotein B mRNA-editing catalytic polypeptide-like 3) and risk of cancer. We conducted a meta-analysis of all eligible case–control studies to find out the associations between APOBEC3 deletion and cancer risk by pooling the odds ratios (ORs) and corresponding 95% confidence intervals (CIs). Overall, the findings from 20 studies (13 articles) involving of a total of 26 225 cases and 37 201 controls revealed that DD genotype was associated significantly with increased cancer risk compared to II genotype (OR = 1.25, 95% CI = 1.01–1.56, P = 0.04). Stratified analysis from 10 studies including 14 757 cases and 17 930 controls revealed that I/D variant significantly increased the risk of breast cancer in heterozygous codominant (OR = 1.15, 95% CI = 1.03–1.28, P = 0.02, ID vs II), dominant (OR = 1.15, 95% CI = 1.01–1.31, P = 0.03, ID + DD vs II), overdominant (OR = 1.11, 95% CI = 1.05–1.25, P < 0.0001, ID vs DD + II) and allele (OR = 1.15, 95% CI = 1.13–1.25, P = 0.03, D vs I) inheritance models. In conclusion, the data propose that APOBEC3 deletion is significantly associated with increased susceptibility to cancer in overall and breast cancer. Our findings require well-designed replication in a larger independent genetic association study with larger sample sizes in diverse ethnicities.
