Genetic polymorphism in ERCC5 and breast cancer risk.

ABSTRACT: ERCC5 plays crucial role in excision repair DNA damage induced by UV in NER pathway. Single neuleotide polymorphism in ERCC5 were responsible for different cancers. Therefore, current study evaluated the relationship between ERCC5 (rs1047768 T>C) polymorphism and the risk of breast cancer in Pakistani population. The rs1047768 polymorphism was screened among 175 females including one hundred breast cancer cases and age matched seventy-five healthy controls. Genotyping was performed with Tetra amplification-refractory mutation system (ARMS) PCR and products were observed through electrophoresis. Multivariate logistic regression was used to calculate odds ratio (OR) and 95% confidence interval (95% CI) investigating relationship between genotypes, clinical parameters and risk of breast cancer. Statistical analysis exhibited significant relationship between the TC genotype (OR=7.2, 95% CI=1.5-34.3) and increased breast cancer risk. Moreover, family history (OR=6.25; 95% CI= 2.61-15.00) and late menopause (OR=2.41; 95% CI=1.20-4.83) were found to be breast cancer associated risk factors. In conclusion, ERCC5 (rs1047768 T>C) polymorphism may contribute towards increased risk of breast cancer in Pakistani population.
