Background: 8-Oxo-7, 8-dihydro-2'-deoxyguanosine (8-oxodG) is a potent DNA damage marker that leads to cellular oxidative stress. It is a DNA-repair enzyme that participates in “8-oxodG” DNA adducts removal. Previous studies show weak associations of rs1052133 (hOGG1) in breast cancer patients of Northern India. We performed this study to explore the variant rs1052133 (hOGG1) with breast in the population of Jammu and Kashmir (J and K).
Method: A polymerase chain reaction–restriction fragment length polymorphism -based single-nucleotide polymorphism (SNP) genotypic study was carried out in peripheral blood samples of 165 breast cancer patients and 200 healthy controls, using specific primers. Sanger sequencing verified the results.
Results: hOGG1-Ser326Cys polymorphism occurred frequently in cases as compared with controls. Data were evaluated by SPSS V.13 software, following Hardy–Weinberg equilibrium (P = 0.002 at OR 2.57; 95% CI [1.68–3.93]), which showed that the SNP rs1052133 had a significant association with increased risk of breast cancer.
Conclusion: Overall, the results of this analysis show that the hOGG1-Ser326Cys polymorphism may be associated with an increased risk for breast cancer in the J and K population.
