Genetic variants in the acylphosphatase 2 gene and the risk of breast cancer in a Han Chinese population

Abstract

We performed a case-control study to investigate the associations between seven single nucleotide polymorphisms (SNPs) in the acylphosphatase 2 (ACYP2) gene and breast cancer (BC) risk in a Han Chinese population. There were 183 BC cases and 195 healthy controls included in the study. The SNPs were genotyped using the Sequenom MassARRAY platform. Logistic regression (adjusted for age group, body mass index [BMI], and menopause status), was used to evaluate the associations between the various genotypes and BC risk. Statistical analysis revealed that rs12621038 was associated with a decreased risk of BC in the allele (T vs. C: odds ratio [OR] = 0.71, 95% confidence interval [95% CI] = 0.52–0.94; p = 0.016), homozygous (TT vs. CC: OR = 0.47, 95% CI = 0.24–0.85; p = 0.014), dominant (OR = 0.62; 95% CI = 0.40−0.96; p = 0.032), and additive (OR = 0.68; 95% CI = 0.50–0.92; p = 0.012) models. In addition, we found that rs1682111 and rs17045754 were associated with the risk of BC and correlated with recurrence, and that rs6713088 correlated with tumor size. In sum, our findings reveal significant associations between SNPs in the ACYP2 gene and BC risk in a Han Chinese population.
