      CaseNotHPOs: N/A

      CaseNotHPOsFreeText: On admission to the hospital, proband had no sign or symptoms of bleeding.

      ProteinExpression: In comparison to normal platelets, very low αIIbβ3 (1,053 ± 544 copies/platelet, n=3) and αvβ3 (755 ± 180 copies/platelet, n=3) expression were measured on the cell surface expression of our patient’s platelets.

      PlateletAggregation: Light transmission aggregometry showed his platelets were unable to respond to ADP, collagen, arachidonic acid, and epinephrine; however, platelet agglutination in response to ristocetin was normal.

      CasePreviousTesting: To identify the molecular genetic defect in this patient, we isolated genomic DNA from the patient’s leukocytes and amplified all exons of ITGA2B and ITGB3 gene by PCR.

      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.

      GenotypingMethod: Sequence variations in the VWF were identified through direct sequencing, while the detection of large rearrangements utilized the multiplex ligation-dependent probe amplification (MLPA) technique or assessed copy number variations (CNVs). Sanger sequencing methodology was applied for VWF analysis in patients investigated prior to 2016 (approximately 14% of IPs), whereas next-generation sequencing (NGS) was employed for the analysis of VWF in patients inspected from 2017 onwards (about 86% of IPs). In both strategies, the entire VWF, encompassing all 52 exons, intron/exon boundaries, and promoter regions, was analyzed.

      CasePreviousTesting:

      GenotypingMethod: Genetic analysis was performed at the laboratory of hematology of the Radboud University Medical Center in Nijmegen. Ion semiconductor sequencing (Ion-Torrent) was used to analyze the VWF gene from peripheral blood obtained in EDTA tubes or from saliva samples. The 52 exons of VWF gene were analyzed including ±20 bp exon-intron boundaries. If no VWF gene variant was detected, multiplex ligation-dependent probe amplification (MLPA) analysis was performed to find large deletions or duplications. Thus, MLPA was performed in 183 patients (46.9%). All variants were confirmed with Sanger sequencing.

    1. In family 1, the proposita (1A)

      Case#: 1A

      DiseaseAssertion:

      FamilyInfo: Family 1. Her 2 offspring, 1B (son) and 1C (daughter), reported minor bleeding symptoms that had not required treatment. 1B was found to be heterozygous for Trp1745Cys only and 1C was heterozygous for Arg760His only, confirming that these mutations are in trans in 1A.

      CaseHPOFreeText4: was an elderly woman with lifelong bleeding episodes, including epistaxis, ecchymosis, menorrhagia, and prolonged bleeding after dental extractions, requiring multiple medical interventions. The coexistence of both mutations appears to produce a more significant bleeding disorder as the bleeding score in 1A (8) was higher than that in either of her children (4 and 2). The position of Trp1745 in the A3 domain is shown in Figure 2. Both persons with this mutation (1A and 1B) had markedly reduced ratios of VWF collagen-binding activity to VWF antigen (CB:Ag) with type III collagen (0.1 and 0.3, respectively) and type I collagen (0.2 and 0.3, respectively). The ratio of VWF:RCo to VWF:Ag (RCo:Ag) was near unity in both persons, and VWF multimer analysis (Figure 1B) and RIPA were normal. Closure times in the PFA-100 were mildly prolonged with the ADP cartridge (1A = 173 seconds, 1B = 189 seconds, NR < 112 seconds). With the epinephrine cartridge, the closure time was prolonged in 1A only (1A = 271 seconds, 1B = 90 seconds, NR < 179 seconds).

      CasePreviousTesting: Fifty-one primer sets were used to amplify the essential regions of VWF (52 exons, flanking intronic regions, 5′ promoter region, and the 3′ untranslated region).

      Gene: VWF

      Variant: 1A demonstrated compound heterozygosity for 2 mutations in the VWF gene. The first is a novel mutation in exon 30:c.5235 G → T resulting in Trp1745Cys and the second is c.2279 G → A resulting in Arg760His.
