<prompt> Answer this question truthfullyWhat classification does Glanzmanns thrombasthenia fall under?  <response>: <reason> Glanzmanns thrombasthenia is mainly divided into the following types: Glanzmann thrombasthenia GT is an autosomal recessive inherited qualitative platelet disorder characterized by absence or reduction of platelet glycoprotein GPIIb or GPIIIa or CD61. Glanzmann thrombasthenia is classified into three typesPatients with less than 5 of normal GPIIbIIIa are classified as type I Type II variants have 5 to 20 normal GPIIbIIIa ype III possess near-normal GPIIb IIIa levels but dysfunctional receptorsThe subtypes vary based on ethnicity. For example, Type I is more common in Arabs and Iraqi-Jews living in Israel, whilst type II is relatively frequent in the Japanese population. This subset includes patients with platelets expression of αIIbβ3 more than 20 in which mainly the platelets are able to aggregate but they present the clinical phenotype of GT. The reason being that the stimulated platelets can not bind to soluble Fg or antibodies recognizing activation-dependent determinants on αIIbβ3. It is due to a single amino acid substitution. Acquired GT is defined by inhibition of platelet αIIbβ3 actual function due to the attack of autoantibodies. These antibodies can be produced in numerous disorders such as hematologic malignancy, transfusion, drugs and autoimmune diseases.
