ProteinExpression: Standard glycoprotein analysis confirmed the absence of αIIbβ3 in their platelets but while western blotting failed to reveal αIIb, residual β3 was at about 10% of usual levels and of normal migration (illustrated for GT1 in supplemental Figure 1).

PlateletAggregation: Platelets of all 3 patients failed to aggregate in response to a range of physiologic agonists but were agglutinated by ristocetin. Clot retraction was also defective.
