Congenital prekallikrein deficiency
A rare genetic coagulation disorder characterized by the usually incidental laboratory finding of a prolonged activated partial thromboplastin time (aPTT) but normal prothrombin time due to a deficiency of normal prekallikrein or the presence of nonfunctional prekallikrein. Most patients remain clinically asymptomatic although an association with cardiovascular conditions (hypertension myocardial infarction other coronary artery diseases and ischemic strokes) and venous thrombosis as well as rare cases with increased bleeding tendency have been reported.
