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
