      ProteinExpression: Showed 10-20% of αIIbβ3 expression measured by flow cytometry

      PlateletAggregation: Platelet aggregation showed no response to ADP and collagen but normal response to ristocetin

      CasePreviousTesting: All exons from ITGA2B and ITGB3 genes were amplified by PCR using intronic primers. DNA sequencing was determined by Sanger sequencing.

      Gene: ITGB3
