The Bernard-Soulier syndrome ranked seventh among the most common coagulation disorders; it is a rare genetic disease, characterized by dysfunction or absence of the glycoprotein Ib-IX-V platelet complex, which is the main receptor of von Willebrand factor, important in platelet adhesion to the subendothelium. Its incidence can be more than 1 per 1 million because it is often misdiagnosed if the patient does not present with the typical clinic or if there are no conclusive laboratory results. The syndrome presents macrothrombocytopenia with variable platelet counts as well as prolongation of the coagulation time. To date, more than 100 mutations related to the components of the platelet complex have been described, the presentation of the disease can become very heterogeneous even in patients who have an identical mutation.
