    1. A 30year old primigravida type-I GT patient

      Case1: 30 year old, Female (primigravada), ethnicity not reported

      DiseaseAssertion: Type-1 Glanzmann thrombasthenia

      FamilyInfo: N/A

      ParentalGenotype: See Table 1 (Father wild type and mother has frameshift mutation)

      CasePresentingHPOs: HP:0000132 (Menorrhagia)

      CaseHPOFreeText: Vaginal bleeding, haematochezia

      CaseNotHPOs: N/A

      CaseNotHPOsFreeText: Proband did not have any bleeding manifestations at the age of 16

      ProteinExpression: Using flow cytometry, the test sample (normal plate-lets+patient plasma) showed only 28% GPIIb-IIIa expression as compared to 81.4% GPIIb-IIIa expression seen in the control sample(normal platelets+control plasma) (Fig. 1B) confirming the presence of GPIIbIIIa antibodies in patient plasma.

      PlateletAggregation: Absent aggregation in response to ADP and collagen and normal response to ristocetin (Platelet aggregation information found in Table 1)

      CasePreviousTesting: The mutation analysis was performed by Sanger sequencing of both ITGA2B and ITGB3 genes, which showed a frameshift mutation: c.1230_1230delC, cDNA.1262_1262delC (Y411Tfs*20) due to a single base deletion in exon 13 of ITGA2B

      Gene: ITGA2B

      Variant: NM_000419.3:c.1230del

      LegacyVariant: N/A

      ClinVar: N/A

      CAiD: CA915940214

      gnomAD: N/A

    1. 9

      Case9: Female, 5 years old, Indian

      DiseaseAssertion: Glanzmann thrombasthenia

      FamilyInfo: N/A

      ParentalGenotype: N/A

      CasePresentingHPOs: HP:0000421 (Epistaxis)

      CaseHPOFreeText: Hematomas at the site of injury

      CaseNotHPOs: N/A

      CaseNotHPOFreeText: N/A

      ProteinExpression: HP:0000421

      PlateletAggregation: Diagnosis of GT was made on the basis of impaired platelet aggregation (platelet aggregation was tested against ristocetin, ADP, collagen, epinephrine and arachidonic acid)

      CasePreviousTesting: Multiplex PCR by using GPIIb primers and CSGE analysis were performed

      Gene: ITGA2B

      Variant: NM_000419.3:c.1230del

      LegacyVariant: N/A

      ClinVar: N/A

      CAiD: CA915940214
