We explored the association between single nucleotide polymorphisms (SNPs) in ACYP2 and liver cancer risk. Thirteen SNPs were genotyped in 473 cases and 564 controls. Genetic model, linkage disequilibrium, and haplotype analyses were performed to evaluate the association between ACPY2 SNPs and liver cancer risk. We found that rs6713088 (G allele: odds ratio [OR] = 1.27, 95% confidence interval [CI]: 1.07−1.52, P = 0.007; GG vs. CC: OR = 1.49, 95% CI: 1.02−2.1, P = 0.038), rs843711 (T allele: OR = 1.29, 95% CI: 1.09−1.54, P = 0.004; TT vs. CC: OR = 1.62, 95% CI: 1.13−2.31, P = 0.008), rs843706 (A allele: OR = 1.30, 95% CI: 1.09−1.55, P = 0.003; AA vs. CC: OR = 1.62, 95% CI: 1.13−2.31, P = 0.008), and rs843645 (GG vs. AG: OR = 1.40, 95% CI: 1.07−1.82, P = 0.014) were associated with an increased risk of liver cancer. In contrast, rs1682111 (A allele: OR = 0.77, 95% CI: 0.640−0.94, P = 0.007; AT vs. TT: OR = 0.69, 95% CI: 0.53−0.91, P = 0.007), rs843720 (additive model: OR = 0.82, 95% CI: 0.68−1.00, P = 0.049), ATATCGCC and CG haplotypes (OR = 0.76, 95% CI: 0.62−0.92, P = 0.006; OR = 0.78, 95% CI: 0.65−0.93, P = 0.006, respectively) were significantly decreased liver cancer risk. Our results confirmed that rs6713088, rs843645, rs843711 and rs843706 were significantly increased liver cancer risk, but rs1682111, rs843720 and haplotypes (ATATCGCC and CG) were significantly decreased liver cancer risk in a Han Chinese population.
