CasePreviousTesting: To detect mutations in ITGA2B or ITGB3, total RNA from peripheral blood was used for cDNA synthesis for RT-PCR.

CaseHPOFreeText: Article mentions patients presented with variable bleeding diathesis and Table 1 shows the several phenotypes that were seen among the cohort of 13 patients in this study (this article does not state a specific bleeding phenotype for each proband) "Most of the patients had gross blood loss due to epistaxis (54%), cutaneous bleeding (58%) and menorrhagia (100% of women), while other common symptoms (oral cavity, gastrointestinal, following dental extraction or mild injuries, postpartum, or hematomas) were in general milder.

ProteinExpression: Flow cytometry showed αIIbβ3 expression to be <5%

PlateletAggregation: Article mentions the disorder was indentified by platelet testing consisting in severely impaired aggregation in response to all physiological agonists and also TMA (See Table 4). Ristocetin-induced platelet aggregation was normal or reduced to some extent.

CasePreviousTesting: To detect mutations in ITGA2B or ITGB3, total RNA from peripheral blood was used for cDNA synthesis for RT-PCR. Using specific oligonucleotides and conditions, they amplified and sequenced ITGA2B and ITGB3 by Sanger sequencing, and every mutation found in cDNA was confirmed on DNA samples
