Platelet Dysfunctions and Rare Bleeding Disorders
CHS has descriptions of platelet function disorders that includes more information on the following:
Disorder of platelet adhesion – Bernard-Soulier Syndrome
It is caused by a deficiency on the surface of the platelet in an area called Glycoprotein Ib/IX. As a result, platelets fail to stick and clump together at the site of the injury.
Disorder of platelet aggregation – Glanzmann thrombasthenia
It is caused by a deficiency of a protein on the surface of the platelet, called Glycoprotein IIb/IIIa. As a result, platelets fail to form a plug at the site of an injury.
Storage Pool Deficiencies are a group of disorders caused by problems with platelet granules.
Disorders of platelets procoagulant activity – Scott syndrome
Combined abnormalities of number and function
