CD79A and Venous thrombosis: An analysis of the relationship between the presence of aPL and the incidence of thrombosis showed an OR (CI 95%) of 6.67 (1.5–30.2), p = 0.014, meaning that patients with positive IgA anti-β2GPI have an incidence of thrombosis over six times higher than those who have normal antibody concentrations; the patients with thrombosis had a significantly higher positive percentage of IgA anti-β2GPI than the group of patients without thrombosis (25.0% vs. 4.8%, p = 0.029) (Figure 1).
