Antiphospholipid antibody (APLA) syndrome is an autoimmune condition wherein proteins bound to a certain fat found in the membranes of cells or phospholipids are attacked by the body’s immune system. Mostly observed in young women, the presence of these abnormal proteins in the blood causes improper blood flow, leading to the development of life-threatening clots in the arteries and veins. Pregnant women with this condition may also experience problems in fetal development or suffer from miscarriages and other complications in pregnancy, such as preeclampsia.
