Case1: (M.S) Female, 19 years old, Caucasian

DiseaseAssertion: Glanzmann thrombasthenia

FamilyInfo: N/A

ParentalGenotype: The mutation has been inherited from proband's parents who are heterozygous for the same mutation the proband has.

ProteinExpression: See Fig 4 for flow cytometry analysis of protein expression

PlateletAggregation: Absence of platelet aggregation in response to all agonists tested i.e. ADP, collagen, platelet activating factor acether thrombin, and arachidonic acid; however, ristocetin induced platelet aggregation was normal

CasePreviousTesting: Sequenced patient's GPIIIa exons encompasing a highlight conserved reion of GPIIIa.

Gene: ITGB3

Case1: (Patient L.W) Male, 55 years old, ethnicity not specified

DiseaseAssertion: Glanzmann thrombasthenia

FamilyInfo: N/A

ParentalGenotype: Father passed away and mother has not yet been studied

CasePresentingHPOs: HP:0004406, HP:0006298, HP:0002239

CaseHPOFreeText: Pharyngeal bleeding

CaseNotHPOs: N/A

CaseNotHPOFreeText: N/A

ProteinExpression: Surface expression levels found in Table 2

PlateletAggregation: Absent platelet aggregation tests in response to ADP but a normal initial response to ristocetin

CasePreviousTesting: Sequence analysis of GPIIb RNA was performed. Using 10 pairs of primers that hybridize to sequences specific for GPIIb cDNA, PCR products were generated by RT-PCR from total RNA of the patient and a normal control
