This syndrome is a disorder characterized by recurrent venous or arterial thrombosis and/or fetal losses associated with characteristic laboratory abnormalities, such as persistently elevated levels of antibodies directed against membrane anionic phospholipids (anticardiolipin antibody, antiphosphatidylserine) or their associated plasma proteins, predominantly beta-2 glycoprotein I (β2GPI), or evidence of a circulating anticoagulant. Here, APOH is linked to Arterial thrombosis.
