What causes thrombotic thrombocytopenic purpura (TTP)?
A lack of activity in the ADAMTS13 enzyme (a type of protein in the blood) causes thrombotic thrombocytopenic purpura (TTP). The ADAMTS13 gene controls the enzyme, which is involved in blood clotting. Not having enough enzyme activity causes overactive blood clotting. In TTP, blood clots form in small blood vessels throughout the body.
What causes TTP blood disorder?
TTP, as with other microangiopathic hemolytic anemias (MAHAs), is caused by spontaneous aggregation of platelets and activation of coagulation in the small blood vessels. Platelets are consumed in the aggregation process and bind vWF .
