摘要: Abstract BACKGROUND: Percentage of free-to-total prostate-specific antigen (%fPSA) is an independent predictor risk for prostate cancer among men with modestly elevated level total PSA (tPSA) in blood. Physiological and pathological factors have been shown to influence the %fPSA value diagnostic accuracy. MATERIALS/METHODS: To evaluate genetic determinants %fPSA, we conducted a genome-wide association study serum by genotyping 642,584 single nucleotide polymorphisms (SNPs) 3192 European ancestry, each tPSA 2.5 10 ng/ml, that were recruited REduction DUtasteride Prostate Cancer Events study. Single P −5 further evaluated controls population-based case-control Sweden (2899 cases 1722 male controls), including 464 having levels ng/ml. RESULTS: We identified two loci associated at significance ( −8 ). The first SNP was rs3213764 = 6.45 × −10 ), nonsynonymous variant (K530R) ATF7IP gene 12p13. This also nominally .015). second locus
