Preferred Name

Hereditary congenital prekallikrein deficiency

Definitions
A rare genetic coagulation disorder characterised 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 ischaemic strokes) and venous thrombosis, as well as rare cases with increased bleeding tendency have been reported.
