Summary

Autosomal dominant Bernard-Soulier syndrome type A2 (BSSA2) is characterized by chronic macrothrombocytopenia with mild or no clinical symptoms, normal platelet function, and normal megakaryocyte count. When present, clinical findings include excessive ecchymoses, frequent epistaxis, gingival bleeding, prolonged menstrual periods, or prolonged bleeding after tooth extraction (Savoia et al., 2001). Genetic Heterogeneity of Bernard-Soulier Syndrome Homozygous or compound heterozygous mutations in the GP1BA gene cause classic autosomal recessive Bernard-Soulier syndrome (BSSA1; 231200).
