Association of XRCC1 Trp194 allele with risk of breast cancer, and Ki67 protein status in breast tumor tissues

Prevalence of Arg194Trp x-ray repair cross-complementing group 1 (XRCC1) genotypes in studied subjects. The prevalence of Arg194Trp XRCC1 gene polymorphism was statistically significant (p<0.05), *between the Trp/Trp (TT genotype) in patients and controls, **between Arg/Arg (CC genotype) in patients and controls, ***between Trp/Trp (TT genotype) and Arg/Arg (CC genotype) in patients, ****between Trp/Trp (TT genotype) and Arg/Arg (CC genotype) in controls
