FamilyInfo: N/A

ParentalGenotype: N/A

CasePresentingHPOs: N/A

CaseHPOFreeText: Inclusion criteria were patients with a history of mucocutaneous bleeding (Figure 1 shows a bar diagram of all the clinical manifestations in the patient cohort in this article)

CaseNotHPOs: N/A

ProteinExpression: Platelet receptor alphaIIbbeta3 protein was analyzed by flow cytometry followed by western blotting

Platelet Aggregation: Inclusion criteria for probands was absent or reduced platelet aggregation with agonists such as ADP, adrenaline, arachidonic acid, and collagen (no mention of ristocetin here-- this article does not tell us the specific aggregation for each proband in the paper)

CasePreviousTesting: For mutation analysis of ITGA2B and ITGB3 genes, DNA extraction from whole blood, PCR, heteroduplex PCR followed by CSGE and DNA sequencing were performed. All 30 exons of ITGA2B and 15 exons of ITGB3, as well as their promoters, were analyzed by CSGE following heteroduplex PCR.
