Involvement in diseasei

Quebec platelet disorder (QPD)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn autosomal dominant bleeding disorder due to a gain-of-function defect in fibrinolysis. Although affected individuals do not exhibit systemic fibrinolysis, they show delayed onset bleeding after challenge, such as surgery. The hallmark of the disorder is markedly increased PLAU levels within platelets, which causes intraplatelet plasmin generation and secondary degradation of alpha-granule proteins.
See also OMIM:601709

Pharmaceutical usei

Available under the name Abbokinase (Abbott). Used in Pulmonary Embolism (PE) to initiate fibrinolysis. Clinically used for therapy of thrombolytic disorders.
