Description : Bernard-Soulier syndrome is an autosomal recessive bleeding disorder caused by a defect in or deficiency of the platelet membrane von Willebrand factor (VWF; 613160) receptor complex, glycoprotein Ib (GP Ib). GP Ib is composed of 4 subunits encoded by 4 separate genes: GP1BA, GP1BB, GP9, and GP5 (173511). - Genetic Heterogeneity of Platelet-Type Bleeding Disorders Inherited platelet disorders are a heterogeneous group of bleeding disorders affecting platelet number, function, or both. Functional defects can involve platelet receptors, signaling pathways, cytoskeletal proteins, granule contents, activation, or aggregation (review by Cox et al., 2011 and Nurden and Nurden, 2011). Platelet-type bleeding disorders include Bernard-Soulier syndrome (BDPLT1); Glanzmann thrombasthenia (BDPLT2; 273800), caused by mutation in the ITGA2B (607759) or ITGB3 (173470) gene; pseudo-von Willebrand disease (BDPLT3; 177820), caused by mutation in the GP1BA gene (606672); gray platelet syndrome (BDPLT4; 139090), caused by mutation in the;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the platelet glycoprotein Ib, beta polypeptide, gene (GP1BB, 138720.0001); Caused by mutation in the platelet glycoprotein Ib, alpha polypeptide, gene (GP1BA, 606672.0001); Caused by mutation in the platelet glycoprotein IX gene (GP9, 173515.0001);

Laboratory abnormalities : Prolonged bleeding time; Reduced platelet glycoprotein Ib complex; Normal platelet aggregation with ADP, collagen, epinephrine; Absent platelet agglutination in presence of ristocetin;

Prefixed ID : #231200;
