Case1: Patient 9, Female, 10 years old
DiseaseAssertion: Glanzmann thrombasthenia III (Diagnosed at 3 months of age)
FamilyInfo: N/A
ParentalGenotype: N/A
CasePresentingHPOs: N/A
CaseHPOFreeText: Bleeding phenotypes are not specified per patient in this article, rather, it states: "Petechia, epistaxis, and prolonged bleeding after trauma were the most common symptoms among studied patients"

ProteinExpression: This patient has type III Glanzmann thrombasthenia; therefore, according to this article, this proband showed normal or near-nromal levels of the GPIIb/IIIa complex via flow cytometry.
PlateletAggregation: Prolonged bleeding time, abnormal clot retraction, impaired platelet aggregation induced by most physiological agonists (ADP, epinephrine, and collagen) except ristocetin, mucosal bleeding, easy bruising, epistaxis, as well as normal prothrombin/acivated partial thromboplastin time, and normal platelet count. (This is among inclusion criteria for this study)
CasePreviousTesting: To identify the underlying molecular mechanism of GPIIb/IIIa complex abnormalities among probands in this study, all the 30 exons of ITGA2B and the 15 exons of ITGB3 were analyzed using PCR–CSGE and DNA sequencing.
