Notes

From SNPedia

rs664677 polymorphism was associated with decreased lung cancer risk and increased breast cancer risk (for lung cancer: TC vs. TT: OR = 0.76, 95% CI 0.62-0.92, CC vs. TT: OR = 0.80, 95% CI 0.64-0.99 and for breast cancer: TC vs. TT: OR = 1.42, 95% CI 1.17-1.73, CC vs. TT: OR = 1.51, 95% CI 1.21-1.87).
