Platelet-specific alloantigens have been implicated in the pathogenesis of immune mediated diseases such as neonatal alloimmune thrombocytopenic purpura, post-transfusion purpura and platelet transfusion refractoriness. Recently, it has been paid attention in terms of an inherited risk factor for coronary thrombosis. Because all the established polymorphisms are located on important receptors for adhesive molecules, including integrins alpha 2 beta 1 and alpha IIb beta 3 and GPIb alpha, effects of these polymorphisms on function of the receptors have been studied. In this review, recent studies on molecular characterization of these polymorphisms will be described.

UI	MeSH Term	Description	Entries
D011110	Polymorphism, Genetic	The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.

D016824	Antigens, Human Platelet	Human alloantigens expressed only on platelets, specifically on platelet membrane glycoproteins. These platelet-specific antigens are immunogenic and can result in pathological reactions to transfusion therapy.

D019039	Platelet Glycoprotein GPIIb-IIIa Complex	Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. It is an integrin complex containing INTEGRIN ALPHAIIB and INTEGRIN BETA3 which recognizes the arginine-glycine-aspartic acid (RGD) sequence present on several adhesive proteins. As such, it is a receptor for FIBRINOGEN; VON WILLEBRAND FACTOR; FIBRONECTIN; VITRONECTIN; and THROMBOSPONDINS. A deficiency of GPIIb-IIIa results in GLANZMANN THROMBASTHENIA.
