KLK15 SNP rs2659056 was found to be associated with risk of prostate cancer in UK stage 1 GWAS only, with OR = 2.01 (95% CI = 1.50–2.68; p = 5.45×10−7), but was not found to be significantly associated with prostate cancer risk in the QLD dataset (OR = 1.16, 95% CI = 0.83–1.62; p = 0.41) or the PLCO study group from CGEMS dataset (OR = 0.95, 95% CI = 0.68–1.33; p = 0.94) (Table S2). This evidence concerns the gene KLK15 and prostate cancer.
