<unk>  can be inherited in an autosomal recessive manner or acquired as an autoimmune disorder. The bleeding tendency in<unk>  is variable, some individuals having minimal bruising, while others have frequent, severe, potentially fatal hemorrhages. Moreover, platelet αIIbβ3 levels correlate poorly with hemorrhagic severity, as virtually undetectable αIIbβ3 levels can correlate with negligible bleeding symptoms, and 10%–15% levels can correlate with severe bleeding. Unidentified factors other than the platelet defect itself may have important roles.
