['MicroRNAs (miRNAs) play critical roles in cervical carcinogenesis. Common single nucleotide polymorphisms (SNPs) in pre/pri-miRNAs may change their property through altering miRNAs expression and/or maturation. Here we aimed to investigate the influence of three common SNPs in pre/pri-miRNAs (pri-miR-26a-1 rs7372209, pre-miR-27a rs895819 and pri-miR-100 rs1834306) on individual susceptibility to cervical cancer.', 'We genotyped these three polymorphisms in 103 cervical cancer cases and 417 cancer-free female subjects using polymerase chain reaction-ligation detection reaction (PCR-LDR) method. Unconditional logistic regression analysis was utilized to estimate the association between these polymorphisms and the risk of cervical cancer.', 'In a logistic regression analysis, we found that the rs895819 polymorphism in pre-miR-27a exhibited a significant effect on cervical cancer risk; T allele (OR = 0.68, 95% CI = 0.49-0.95, P = 0.025), and CT (OR = 0.33, 95% CI = 0.15-0.74, P = 0.007) or TT (OR = 0.33, 95% C I= 0.15-0.72, P = 0.006) genotype were associated with the decreased risk, compared to C and CC respectively. As we used further genotype association models, we found a similar trend of the association in additive (OR = 0.70, P = 0.041) and recessive model (OR = 0.33, P = 0.004). We did not detect any association of the other two SNPs in pri-miR-26a-1 (rs7372209) and pri-miR-100 (rs1834306) with cervical cancer risk.'] Is a genetic variant in pre-miR-27a associated with a reduced cervical cancer risk in southern Chinese women?
