FamilyInfo: N/A

ParentalGenotype: N/A

CasePresentingHPOs: N/A

CaseHPOFreeText: All patients presented with a current or past history of bleeding and a bleeding time >15 min. Bleeding symptoms were evaluated by examining available hospital records. Mild bleeders were defined as those who bled only after trauma or surgery or had minor symptoms, such as epistaxis. Moderate/severe bleeders were defined as those with a history of spontaneous or life threatening hemorrhages, such as gastrointestinal bleeding, or who had repeated episodes requiring platelet transfusions
