Preferred Label : Antiphospholipid syndrome, familial;
Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : Lupus anticoagulant, familial;
Description : The designation 'antiphospholipid syndrome' was proposed for the association of arterial
and venous thrombosis, recurrent fetal loss, and immune thrombocytopenia with a spectrum
of autoantibodies directed against cellular phospholipid components. Anticardiolipin
antibodies may react with cardiolipin and with other negatively charged phospholipids,
including beta-2-glycoprotein I (B2GPI, APOH; 138700). The term 'lupus anticoagulant'
refers to a heterogeneous group of antibodies, most commonly of the IgG type, that
are detected by their inhibitory effect on coagulant-active phospholipid components
of in vitro coagulation tests (summary by Matthey et al., 1989). Shoenfeld et al.
(2008) noted that antiphospholipid syndrome is characterized by up to 30 different
autoantibodies, including those against platelets, glycoproteins, coagulation factors,
lamins, mitochondrial antigens, and cell surface markers. Some of these may have an
additive effect on the prothrombotic tendency of the syndrome. Ruiz-Irastorza et al.
(2010) reviewed pathophysiologic, clinical, diagnostic, and therapeutic advances related
to the antiphospholipid syndrome. Various autoimmune disorders that cluster in families,
including autoimmune thrombocytopenia (188030), are discussed elsewhere (e.g., 109100,
269200).;
