ITPR3 gene haplotype is associated with cervical squamous cell carcinoma risk in Taiwanese women.


ABSTRACT: Host immunogenetic background plays an important role in human papillomavirus (HPV) infection and cervical cancer development. Inositol 1,4,5-triphosphate receptor type 3 (ITPR3) is essential for both immune activation and cancer pathogenesis. We aim to investigate if ITPR3 genetic polymorphisms are associated with the risk of cervical cancer in Taiwanese women. ITPR3 rs3748079 A/G and rs2229634 C/T polymorphisms were genotyped in a hospital-based study of 462 women with cervical squamous cell carcinoma (CSCC) and 921 age-matched healthy control women. The presence and genotypes of HPV in CSCC was determined. No significant association of individual ITPR3 variants were found among controls, CSCC, and HPV-16 positive CSCC. However, we found a significant association of haplotype AT between CSCC and controls (OR = 2.28, 95% CI 1.31-3.97, P = 2.83 × 10-3) and the OR increased further in CSCC patients infected with HPV-16 (OR = 2.89, 95% CI 1.55-5.37, P = 4.54 × 10-4). The linkage disequilibrium analysis demonstrated that ITPR3 association with CSCC was independent of HLA-DRB1 alleles. In conclusion, these findings suggest that AT haplotype in the ITPR3 gene may serve as a potential marker for genetic susceptibility to CSCC.
