Unfolded VWF levels above the 90th percentile in normal controls were associated with an odds of APS (OR: 8.51; CI:3.26 - 22.2; p<0.001), compared to ORs of non-APS thrombosis (OR:5.87; CI:2.07 - 16.7, p=0.001) and AID (OR:3.71; CI:1.40 – 9.87; p=0.009). The gene discussed is AICDA; the disease is Venous thrombosis.
