A congenital bleeding disorder with prolonged bleeding time, absence of aggregation of platelets in response to most agents, especially ADP, and impaired or absent clot retraction. Platelet membranes are deficient in or have a defect in the glycoprotein IIb-IIIa complex (PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX).
platelet abnormality characterized by defective clot formation, impaired aggregation, and prolonged bleeding time; other manifestations include nosebleeds, inappropriate bruising, and excessive bleeding.
A rare, autosomal recessive inherited and less frequently acquired platelet disorder. It is characterized by deficient or dysfunctional glycoprotein IIb/IIIa complex. It leads to defective platelet aggregation, resulting in bleeding.
