Genetic polymorphisms of cytochrome P450 19 and 1B1, alcohol use, and breast cancer risk in Korean women

Br J Cancer. 2003 Mar 10;88(5):675-8. doi: 10.1038/sj.bjc.6600761.


A case-control study was performed to assess the potential influence of CYP19 Arg(264)Cys and CYP1B1 Leu(432)Val polymorphisms on breast cancer risk in a series of Korean breast cancer patients and controls. The results suggest that the CYP19 Arg(264)Cys polymorphism modifies breast cancer risk (OR=1.5, 95% CI=1.1-2.2), especially in association with alcohol consumption (P for interaction=0.04), whereas the CYP1B1 Leu(432)Val polymorphism appears to play no role here.
