Molecular basis of Glanzmann's Thrombasthenia and current strategies in treatment

Abstract

Glanzmann Thrombasthenia, an exceptional inherited platelet disorder is characterized by a complete lack of platelet aggregation due to a defect in the alpha(IIb)beta(3) complex or to a qualitative abnormality of this complex. Advances in molecular biology have permitted to precise the molecular abnormality on alpha(IIb) or beta(3) genes responsible for the disease and have also contributed to a better knowledge of normal platelet physiology. Hemorrhages are the main clinical problem. Current principles of therapeutic management are proposed, with special reference to the risk of platelet alloimmunisation.
