Causes

See the list below:

  • Glanzmann thrombasthenia is a genetic condition. The disease is clinically apparent in patients who are homozygous. Glanzmann thrombasthenia is normally of no clinical significance in patients who are heterozygous for this condition.

  • Rare acquired forms caused by antibodies against αIIb β3 integrin have been described. One such affected patient developed non-Hodgkin lymphoma, [2, 11] and another had no underlying cause. [11] It has also been described with hairy cell leukemia. [12]
