The several studies pointed out diverse predictors of future thrombosis events, such as multiple aPL positivity, the presence of antinuclear antibodies, heart valve disease, a younger age of OAPS, higher adjusted Global Antiphospholipid Syndrome score (aGAPPS) and systemic lupus erythematosus [63,64,66]. Here, FASLG is linked to systemic lupus erythematosus.
