Genetic polymorphisms in DNA repair genes and their association with cervical cancer.

: Carcinoma of cervix is the second most common cancer among women worldwide. The DNA repair network plays an important role in the maintenance of genetic stability, protection against DNA damage and carcinogenesis. Alterations in repair genes and and been reported in certain cancers. We hypothesised an association between +399A/G, +31467G/A and +18067C/T polymorphisms and the risk of cervical cancer. : This study included 525 subjects (265 controls and 260 cervical cancer cases). Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). : Women with GA and AA genotypes of +399A/G showed 2.4-3.8 fold higher risk of cervical cancer ( = 0.001). The +399A* allele was significantly linked with cervical cancer ( = 0.002). However, +31479G/A and +18067C/T polymorphisms did not show any statistically significant associations. : The +399A/G SNP is linked with cervical cancer. We suggest that this variant can be utilized as a prognostic marker for determination of cervical cancer susceptibility.
