We also reported proteins with a colocalised association for one outcome and little evidence for an association with others after correction for multiple testing, such as IFNA14, ISLR2, MMP7, and TNSFRS10B which were associated exclusively with overall prostate cancer [ORIFNA14 = 0.74, 95% CI: 0.70–0.78; ORISLR2 = 0.82, 95% CI: 0.75–0.90; ORMMP7 = 0.67, 95% CI: 0.58–0.76; ORTNFRSf10B = 0.87, 95% CI: 0.83–0.92, Fig. 2]. This evidence concerns the gene ISLR2 and Familial prostate cancer.
