Bernard Soulier Type B


Bernard-Soulier Syndrome (BSS), also sometimes called Giant Platelet Syndrome, is a bleeding disorder characterized by mild to severe thrombocytopenia with large platelets. Onset can begin in infancy or childhood. Common bleeding problems include bruising, nose bleeds, gingival bleeding and menorrhagia. BSS is caused by defects in the von Willebrand factor receptor on the platelet cell surface.

BSS is an autosomal recessive disorder. It has been observed that carriers of a single causative mutation may also have large platelets and mild bleeding problems. Occasionally, the carrier symptoms are so strong that families display dominant inheritance.
