We then performed additional colocalization analyses based on the obtained conditional association statistics, and identified a positive colocalization between the OPN association signal at rs4253311 at the KLKB1 locus and rs1593 for deep venous thrombosis (DVT; H4: p12 = 0.96; S7 Table and S10 Fig). This evidence concerns the gene KLKB1 and Venous thrombosis.
