Abstract

Objective: This study aimed to explore whether VDR polymorphisms (Fok1, Apa1 and Taq1) are associated to the cervical cancer in Thai population. Materials and methods: Subjects of 204 cervical cancer patient and 204 age-matched healthy control were enrolled in the case-control study. VDR polymorphisms were detected by using real-time PCR. Haplotype analysis of three loci was applied to the obtained genotypes. Results: Significantly increased risk for cervical cancer was observed in carriers of TT genotype (p = 0.0388) and T allele (p = 0.0357) of Fok1 and TC genotype (p = 0.0001), CC genotype (p = 0.0160) and the C allele of Taq1 (p = 0.0001). Haplotype analyses revealed a significant correlation between C-T-C, T-G-C and T-T-C haplotypes and elevated risk for cervical cancer (OR = 2.06; 95%CI = 1.06-4.00; p = 0.0313, OR = 2.15; 95%CI = 1.22-3.80; p = 0.0078 and OR = 2.81; 95%CI = 1.53-5.16; p = 0.0006, respectively). Furthermore, haplotype carrying C allele of Taq1 (C-G-C + C-T-C + T-G-C + T-T-C) significantly increased cervical cancer risk with OR of 1.92 (95%CI = 1.32-2.79, p = 0.0006). Conclusion: Our finding revealed an association between VDR polymorphisms and cervical cancer risk. Taq1 C allele might be a molecular marker for cervical cancer development.
