      PlateletAggregation: Absence of platelet aggregation in response to ADP, epinephrine, and collagen but the presence of a normal response to ristocetin

      CasePreviousTesting: Genomic DNA was extracted by a standard protocol from the peripheral blood mononuclear cells of the patient and her parents. The flanking region of exon 25 of the GPIIb gene including the introns was amplified by PCR from the genomic DNA.
