Blood Rev. Signs and symptoms vary greatly from person to person. Glanzmann's thrombasthenia is associated with abnormal glycoprotein IIb/IIIa (GpIIb/IIIa), also known as α IIb β 3, which is an integrin aggregation receptor on platelets. Patients usually present with mucocutaneous bleeding and excessive bleeding associated with trauma and/or surgery. Identify the importance of an interprofessional team to optimize outcomes for patients with Glanzmann thrombasthenia. The αIIbβ3 is a platelet fibrinogen receptor, which is required for platelet aggregation, firm adhesion, and also spreading.
