Final answer:
Glanzmann's Thrombasthenia is the disorder caused by the deficiency in glycoprotein IIb-IIIa resulting in a defect in platelet aggregation. This receptor found on platelets plays a crucial role in blood clotting. The condition leads to symptoms such as easy bruising and nosebleeds.
Step-by-step explanation:
The Autosomal Recessive (AR) disorder due to a deficiency in glycoprotein IIb-IIIa, which results in a defect in platelet aggregation, is called Glanzmann's Thrombasthenia. Glycoprotein IIb-IIIa is a receptor found on the surface of platelets which plays a crucial role in the aggregation of platelets, a key process in blood clotting. Glanzmann's Thrombasthenia, named after the Swiss pediatrician Eduard Glanzmann who first described it, is a rare genetic disorder characterized by impaired clotting of the blood and consequently prolonged bleeding times. The disorder manifests itself in various symptoms such as easy bruising, nosebleeds, gum bleeding, and heavy menstrual bleeding.
