General Discussion
Antiphospholipid syndrome (APS) is a rare immunological disorder characterized by recurring blood clots. Blood clots can form in any blood vessel of the body. The specific symptoms and severity of APS vary greatly from case to case depending upon the exact location of a blood clot and the organ system affected. APS may occur as an isolated disorder (primary antiphospholipid syndrome) or may occur along with another autoimmune disorder such as systemic lupus erythematosus (secondary antiphospholipid syndrome).

APS is characterized by the presence of antiphospholipid antibodies in the body. Antibodies are specialized proteins produced by the body?s immune system to fight infections. In individuals with APS, certain antibodies mistakenly attack healthy tissue. This healthy tissue is a certain proteins that bind to phospholipids. Phospholipids are a type of fat molecule that is involved in the proper function of cell membranes and found throughout the body. The reason for these antiphospholipid antibodies attacking the phospholipid proteins and the process by which they cause blood clots is not known.
