Highly active women harboring variant alleles in CAT rs1001179 were at increased risk of breast cancer compared with women with the common CC genotype (OR = 1.61; 95 % CI, 1.06-2.45).
Here, we investigated the effect of MnSOD (p.Val16Ala, rs4880) and CAT (-262C>T, rs1001179) SNPs on the association between the MD and BC risk in the case-control study of BC MASTOS in Cyprus.
