Platelet glycoprotein 1b alpha polypeptide

Glycoprotein 1b is a receptor exposed on the surface of platelets where it binds von Willebrand factor. Mutations can cause the autosomal recessive or dominant form of Bernard-Soulier syndrome. Genetic variations of this gene have also been associated with nonarteritic anterior ischemic optic neuropathy.
