To investigate the association between CTLA-4 +49A/G polymorphisms and the risk of susceptibility to cervical cancer. A hospital-based case-control study was conducted. 314 cases with primary cervical cancer and 320 healthy controls were collected and genotyped by PCR-based RFLP for +49A/G polymorphisms in the CTLA-4 gene. The A allele and AA genotype of CTLA-4 gene were 32.5% and 9.6% in the patients, and 25.8% and 5.6% in the controls, respectively. Subjects with CTLA-4 +49AA genotype conferred a higher risk of cervical cancer (OR = 2.06, 95%CI: 1.10 - 3.85; P = 0.024). However, the correlation between AA genotype in CTLA-4 polymorphisms and clinicopathological characteristics was not significant. The results of this study suggest that CTLA4 gene is associated with cervical cancer risk and may be a susceptible gene of cervical cancer.
