Study the Association between TP53 (rs12602273C>G) Gene Polymorphism with Susceptibility to the Breast Cancer in North West of Iran

Introduction: The TP53 gene on the short arm of chromosome 17p, which is known as a tumor suppressor gene, encodes the transcription factor p53, and this factor controls cell cycle progression. This study was done to assess the association of TP53 (rs12602273C>G) gene polymorphism with the risk and prognosis of breast cancer in women of northwest of Iran. Methods: In this case-control study, the association of TP53 (rs12602273C>G) gene polymorphism with breast cancer risk was studied in a population, including 100 patients and 100 healthy individuals was investigated by Tetra ARMS-PCR technique. The analysis of the resulting data was done using SPSS version 16 software and JavaStat online statistics package. Results: In the case group, the frequency of CC, CG, and GG genotypes were 81.52, 16.3, 2.17 percent, respectively and they were 79.34, 17.39, and 3.26 percent for the control group. Similarly, C and G allele frequency in case group was 89.67 and 10.32 percent and those in the control group was 88.04 and 11.95 percent, respectively. Statistical analyzes showed no association between genotypic (P>0.05) and allelic (P>0.05) polymorphism (rs12602273C>G) of TP53 gene with breast cancer. Also, the results showed that the studied polymorphism was not associated with the clinical characteristics of breast cancer patients in the Northwest of Iran (P>0.05). Conclusion: These research findings suggest that TP53 polymorphism of rs12602273C>G is not related to the risk of breast cancer. The association of the genotypic distribution of this SNP with the clinical characteristics of the patients was insignificant.
