Glanzmann thrombasthenia
Glanzmann thrombasthenia (GT) is a rare autosomal recessive bleeding syndrome affecting the megakaryocyte lineage and characterized by lack of platelet aggregation. The molecular basis is linked to quantitative and/or qualitative abnormalities of alphaIIb beta3 integrin. This receptor mediates the binding of adhesive proteins that attach aggregating platelets and ensure thrombus formation at si...
متن کاملPatients With Glanzmann Thrombasthenia Lacking Platelet Glycoprotein
Background—Platelets have been suggested to play a role in the early development of atherosclerosis. As one test of this hypothesis, we assessed whether patients with Glanzmann thrombasthenia who lack platelet glycoprotein IIb 3 (GPIIb/IIIa) complexes or both IIb 3 and the more ubiquitous v 3 cell membrane complexes are protected from development of atherosclerosis. Methods and Results—Seven pa...
متن کاملGlanzmann thrombasthenia in a neonate.
Glanzmann thrombasthenia is a qualitative platelet function disorder manifested by skin bleeds, epistaxis, gingival bleeding, gastrointestinal hemorrhage, hematuria, hemarthrosis, intracranial hemorrhage and visceral hematomas. We report a six day old newborn presenting with hematuria following suprapubic aspiration, who was diagnosed as Glanzmann thrombasthenia. We believe it to be the younges...
متن کاملGlanzmann thrombasthenia in Pakistan: molecular analysis and identification of novel mutations.
Glanzmann thrombasthenia (GT) is an inherited genetic disorder affecting platelets, which is characterized by spontaneous mucocutaneous bleeding and abnormally prolonged bleeding in response to injury or trauma. The underlying defect is failure of platelet aggregation due to qualitative and/or quantitative deficiency of platelet integrin αIIbβ3 resulting from molecular genetic defects in either...
متن کاملNovel Mutations in the GPIIb and GPIIIa Genes in Glanzmann Thrombasthenia.
BACKGROUND: Glanzmann thrombasthenia (GT) is an inherited autosomal recessive platelet disorder characterized by a complete or partial lack, or mutation, of the GPIIb/IIIa complex (integrin α(IIb)β(3)) on the thrombocytes' surface, leading to a severe bleeding syndrome. MATERIAL AND METHODS: Molecular genetic analysis was performed in patients with suspected GT. The aim of the present study was...
