WFDC1 and urinary bladder cancer: The colocalization analysis revealed that, among the 115 plasma proteins associated in the Olink dataset, three proteins - SLURP1, LY6D, and WFDC1 - exhibited strong evidence of colocalization with bladder cancer risk loci (PP.H3+PP.H4 values ~0.9999, 0.9998, and 0.758, respectively; Figure 3A-C, Supplementary Table S3).
