We genotyped three variants associated with prostate cancer (rs10090154, rs13254738, and rs7000448), one associated with both prostate and colorectal cancer (rs6983267), and one associated with breast cancer (rs13281615) in a series of 1,499 breast cancer cases and 1,390 controls.
Significant associations were observed for rs4430796 TT with Gleason scores of ≥ 7 (OR = 1.76, 95% CI = 1.14-2.73) and prostate-specific antigen (PSA) levels of ≥ 10 ng/ml at diagnosis (OR = 1.63, 95% CI = 1.01-2.63), as well as for rs6983267 GG with stage 3-4 CaPs (OR = 1.91, 95% CI = 1.01-3.61).
