The absence of ANXA2 affects tissue-type plasminogen activator (tPA)-dependent plasmin generation on endothelial cell surfaces, which may contribute to cerebral venous thrombosis and systemic lupus erythematosus, leading to thrombus formation (Ao et al., 2011; Cesarman-Maus et al., 2011; Fassel et al., 2021). The gene discussed is PLG; the disease is systemic lupus erythematosus.
