      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.

It comprised all 52 exons, intronic flanking regions, promoter and 3’UTR region of the VWF gene. Libraries were prepared by using the Twist NGS target enrichment solution (Twist BioScience) according to the manufacturer protocol. Samples were analyzed on a NovaSeq 6000 sequencer (Illumina) with a median read depth of 2500X by using the 300-cycle S1 NovaSeq 6000seq reagent kit with 150-bp paired-end reads. The raw data were analyzed with Mutect21 and Vardict2 tools. The inhouse NGSreport software (CHU Lille) was used for data visualization, sequences check and conservation of variants with high quality metrics. In some cases, patients genomic DNA was screened for sequence variations (large deletions, insertions and duplications) by Multiplex Ligation-dependent Probe Amplification (MCR Holland).

      GenotypingMethod: All samples were analyzed by captured-based high throughput sequencing which was performed with a custom-design of the VWF gene provided by Twist BioScience (San Francisco, USA). It comprised all 52 exons, intronic flanking regions, promoter and 3’UTR region of the VWF gene. Libraries were prepared by using the Twist NGS target enrichment solution (Twist BioScience) according to the manufacturer protocol. Samples were analyzed on a NovaSeq 6000 sequencer (Illumina) with a median read depth of 2500X by using the 300-cycle S1 NovaSeq 6000seq reagent kit with 150-bp paired-end reads. The raw data were analyzed with Mutect21 and Vardict2 tools. The inhouse NGSreport software (CHU Lille) was used for data visualization, sequences check and conservation of variants with high quality metrics. In some cases, patients genomic DNA was screened for sequence variations (large deletions, insertions and duplications) by Multiplex Ligation-dependent Probe Amplification (MCR Holland).

      CasePreviousTesting:

      GenotypingMethod: All samples were analyzed by captured-based high throughput sequencing which was performed with a custom-design of the VWF gene provided by Twist BioScience (San Francisco, USA). It comprised all 52 exons, intronic flanking regions, promoter and 3’UTR region of the VWF gene. Libraries were prepared by using the Twist NGS target enrichment solution (Twist BioScience) according to the manufacturer protocol. Samples were analyzed on a NovaSeq 6000 sequencer (Illumina) with a median read depth of 2500X by using the 300-cycle S1 NovaSeq 6000seq reagent kit with 150-bp paired-end reads. The raw data were analyzed with Mutect21 and Vardict2 tools. The inhouse NGSreport software (CHU Lille) was used for data visualization, sequences check and conservation of variants with high quality metrics. In some cases, patients genomic DNA was screened for sequence variations (large deletions, insertions and duplications) by Multiplex Ligation-dependent Probe Amplification (MCR Holland).

CasePresentingHPOs: HP:0000421 (Epistaxis), HP:0000132 (Menorrhagia), HP:0001934 (Persistent bleeding after trauma — bleeding from minor wounds), HP:0004846 (Prolonged bleeding after surgery — post-surgical bleeding, bleeding at tooth extraction), HP:0030130 (Impaired VWF collagen binding activity; VWF:CB/Ag ratio 0.18, nv ≥0.8), HP:0030129 (Impaired VWF:RCo; VWF:RCo/Ag ratio 0.22, nv ≥0.8), HP:0030132 (Absence of large VWF multimers) CaseHPOFreeText: VWF:Ag markedly ELEVATED at 2.50× normal (nv 0.5-1.6). Absolute VWF:RCo 0.54 and VWF:CB 0.46 (both near/within the lower end of normal in absolute terms, nv ≥0.5, but severely reduced relative to the elevated antigen). VWF:GPIbα binding 0.74 absolute / 0.30 ratio. FVIII:C 1.08 (normal, nv ≥0.6) with reduced FVIII-binding ratio (F8Br 0.61, at threshold, nv ≥0.6). VWF propeptide:Ag ratio (ppr) 0.71, reduced (nv 0.8-2.2) — indicates decreased clearance of mature VWF relative to propeptide. PFA-100 closure times markedly prolonged (Epinephrine and ADP both >300 sec, nv ≤165/≤118). Hematoma (bruising) and oral cavity bleeding also reported. Post-partum bleeding ultimately requiring hysterectomy. Historical DDAVP test performed in this patient specifically showed findings consistent with delayed VWF clearance. Oral contraceptive/desmopressin use not specified. CaseNOTHPOs: NA CaseNOTHPOFreeText: NA CasePreviousTesting: Extensive prior negative testing — partial sequencing in the original 1993 study plus subsequent complete Sanger sequencing of all VWF coding exons by multiple independent groups over ~20 years found no candidate mutation. The causative variant was only found via MLPA (multiplex ligation-dependent probe amplification), which detects copy-number changes that exon sequencing alone misses. Not genome-wide; VWF-targeted. GenotypingMethod: MLPA identified signal gain at exons 9-10 in all 4 family members; confirmed by duplication-junction-specific RT-PCR (sense primer in exon 10, antisense in exon 9) and by RT-PCR/sequencing across exons 8-11. Full genomic characterization (PCR primer walking, RepeatMasker, MFold in silico DNA-folding analysis) defined a complex rearrangement: a 5,047 bp duplication (intron 8 through part of intron 10, including exons 9 and 10) plus two deletions (1,348 bp and 2,301 bp) within intron 10, apparently mediated by inverted Alu repeat elements (proposed mechanism: replication slippage for the duplication, a stable Alu3/Alu4 inverted-repeat DNA secondary structure for the deletion). PreviouslyPublished: PMID 8324222 (Ledford MR, Rabinowitz I, Sadler JE, Kent JW, Civantos F. "New variant of von Willebrand disease type II with markedly increased levels of von Willebrand factor antigen and dominant mode of inheritance: von Willebrand disease type IIC Miami." Blood. 1993;82:169-75) — this is the original report of this same family. Gene: VWF Variant: Heterozygous complex in-frame duplication of VWF exons 9-10 (net transcript-level effect), D1 domain (VWF propeptide region). Recombinant expression studies (not patient-specific, applies to the variant generally): "homozygous" mutant VWF secreted only as dimers (no higher-order multimers); co-expression with WT VWF reproduced the patients' plasma multimer pattern exactly; mutant retained in unusually large intracellular granules colocalizing with PDI in the ER; ADAMTS13 proteolysis was not resistant, but an aberrant extra proteolytic band appeared in both patient plasma and recombinant mutant; infusion of recombinant mutant VWF into VWF-/- mice showed significantly prolonged half-life vs. WT (mean residence time 3.15h vs 1.90h, p=0.015), supporting decreased clearance as the mechanism for the paradoxically elevated VWF:Ag.

      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.

      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. Classification and Characterization of Hereditary Types 2A, 2B, 2C, 2D, 2E, 2M, 2N, and 2U (Unclassifiable) von Willebrand Disease

      PMID: 17000885

      Gene: VWF

      HGNC: 12726

      Disease: von Willebrand disease type 2M

      MONDO: 0015630

      InheritancePattern: Autosomal Dominant

      Prevalence: Overall VWD prevalence is estimated to be as high as 1 in 100 in the general population, with 1 in 10,000 pursuing tertiary care referral (PMID: 28847738).

      Penetrance: Fully penetrant / nearly fully penetrant for most pathogenic type 2 variants

    1. We report on the coinheritance of mild haemophilia A and type 1 von Willebrand disease (VWD) in a genetically characterized Italian family. The proband is a 56-year-old man carrying both the c.2167G>A mutation in the factor VIII (FVIII) gene (responsible for p.A723T substitution) and the c.4751A>G mutation (p.Y1584C) in the von Willebrand factor (VWF) gene.

      Case: Proband (II-1), male, 56yo, Italian

      DiseaseAssertion: VWD1 and Hemophilia A

      FamilyInfo: Pedigree in Fig. 1 - Father had VWD1 and Mother had Hemophilia A - parents have normal or higher VWF levels, and normal FVIII/VWF:Ag ratios, as well as a normal bleeding score; 2 daughters carry F8 variant

      ParentalGenotype(s): Paternal = NM_000552.4(VWF):c.4751A>G (p.Tyr1584Cys); Maternal = NM_000132.3(F8):c.2167G>A (p.Ala723Thr)
