      Case1: GT-1, age, gender, ethnicity not specified

      DiseaseAssertion: Glanzmann thrombasthenia type II

      FamilyInfo: Segregation analysis confirmed in presence of heterozygous mutations in this proband.

      ParentalGenotype: Although segregation analysis confirmed, we do not know which variant in particular came from mom or dad.

      CasePresentingHPOs: N/A

      CaseHPOFreeText: Patients presented with a variable bleeding diathesis; most patients had epistaxis (54%), cutaneous bleeding (58%), and menorrhagia (100% of women) while other common symptoms (oral cavity, GI, following dental extraction of mild injuries, postpartum, or hematomas) were in general milder. There is no specific phenotypes attached to probands in this paper.

      CaseNotHPOs: N/A

      CaseNotHPOsFreeText: N/A

      ProteinExpression: Flow cytometry showed that αIIbβ3 expression was between 5% and 20%

      PlateletAggregation: There was severely impaired aggregation in response to all physiological agonists, and ristocetin induced platelet agglutination was normal or reduced to some extent.

      CasePreviousTesting: Total RNA from peripheral blood was used for cDNA synthesis for RT-PCR. Then, using specific oligonucleotides and conditions, they amplified and sequenced ITGA2B and ITGB3 by Sanger sequencing. Every mutation found in cDNA was confirmed in DNA samples.

      NoEvidence: This article does not mention Glanzmann thrombasthenia probands with variants in ITGA2B and/or ITGB3; therefore, there is no evidence. In this study, they developed an assay method of platelet adhesion to collagen in which citrated platelet rich plasma could be used as well as washed platelets in the presence of anti GPIIb/IIIa monoclonal antibody. Here, they provided the first direct evidence that the activation depended platelet adhesion to collagen is induced by ADP and that this adhesion is also mediated by GPIa/IIa.
