Thrombasthenia of Glanzmann and Naegeli

Clinical feature: 

Definition: Glanzmann thrombasthenia is a rare autosomal recessive bleeding disorder as a result of platelet's inability to bind fibrinogen and form clots. This failure is caused by glycoprotein IIb-IIIa complex deficiency. Underlying mutations can be found in two distinct genes, ITGA2B and ITGB3.

Diagnostics: 

Differential: Differential diagnosis includes other hereditary bleeding disorders caused by platelet dysfunction. Bernard-Soulier syndrome is characterized by makrothrombocytopenia.  » » »
