    1. A 19-year-old woman was diagnosed with a reduced coagulation factor VIII activity of 30% after bleeding complications from wisdom tooth surgery

      Case: Female, 19 y.o., ethnicity unknown.

      DiseaseAssertion: VWD2N

      FamilyInfo: Proband has one older symptomatic sister who shares an identical compound heterozygous genotype, presenting with a mild bleeding tendency, reduced FVIII activity (20-30%), and severely reduced FVIII binding (<2%). The family features one younger unaffected sister who tested negative for both variants, and an unaffected carrier mother. Both parents had normal factor VIII, and there was no male relative with reduced factor VIII or bleeding symptoms.

      ParentalGenotype(s): Mother is heterozygous for the c.2561G>A (p.R854Q) variant, negative for the c.2402G>A (p.S801N) variant, and has normal baseline factor VIII levels, confirming the sisters' variants are in trans. Father unavailable/not tested.

      CasePresentingHPOs: HP:0004846 (Prolonged bleeding after surgery), HP:0003645 (Prolonged partial thromboplastin time).

      CaseHPOFreeText: Index patient experienced bleeding complications following wisdom tooth surgery. Factor VIII binding activity is reduced at 32%. Reduced coagulation factor VIII activity (30%). Prolonged activated partial thromboplastin time (aPTT) of 37 seconds.

      CaseNOTHPOs: HP:0001873 (Thrombocytopenia), HP:0012147 (Reduced quantity of von Willebrand factor), HP:0030130 (Impaired von Willebrand factor collagen binding activity).

      CaseNOTHPOFreeText: Normal vWF antigen (vWF:Ag) levels (101%), normal vWF activity (116%), normal vWF-collagen-binding activity (104%), normal vWF multimer distribution structures, normal hemoglobin level (128 g/L), and normal Prothrombin Time (PT/QUICK) of 83%.

      CasePreviousTesting: Siblings did not carry any known mutations in the F8 gene or the LMAN1 and MCFD2 genes (which encode for endoplasmic reticulum carrier proteins of coagulation factors V and VIII).

      GenotypingMethod: Direct sequence analysis of VWF exons 18-20.

      PreviouslyPublished: NA.

      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).

      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).

      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).

      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).

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).

    2. The proband was a 9-year-old boy, whose family pedigree is shown in Fig. 1. He suffered from frequent bruise, epistaxis, prolonged bleedings from small wounds, and delayed wound healing.

      Case: Patient V-2, Male, 9 years old (proband) DiseaseAssertion: Type 2A VWD, based on history of abnormal bleeding, low plasma VWF:Ag and activity, low FVIII:C, and lack of plasma HMW VWF multimers. FamilyInfo: Proband of a pedigree (Fig. 1) with 5 affected individuals (V-2, III-3, IV-2, IV-3, IV-4) across multiple generations, all carrying the same variant; unaffected father (IV-5) does not carry it. ParentalGenotype(s): Mother (IV-4) heterozygous for the variant, affected. Father (IV-5) does not carry the variant, unaffected (normal VWF:Ag 95.2 IU/dL, normal multimer pattern). CasePresentingHPOs: HP:0000421 (Epistaxis), HP:0001934 (Persistent bleeding after trauma — "prolonged bleedings from small wounds"), HP:0012147 (Reduced quantity of VWF; VWF:Ag 20.5 U/dL), HP:0030129 (Impaired VWF:RCo; VWF:Rco 6.2 U/dL), HP:0030132 (Absence of large VWF multimers — plasma), HP:0011871 (Impaired RIPA; 28.5%), HP:0003645 (Prolonged partial thromboplastin time; APTT 58.1 sec) CaseHPOFreeText: Frequent bruising, delayed wound healing (no matching HPO code in the approved list); FVIII:C 25.0 U/dL (nv 50-150); TT 16.7 sec and PT 14.2 sec both within normal range. CaseNOTHPOs: NA CaseNOTHPOFreeText: Platelet-associated VWF multimers were normal (HMW multimers present, indistinguishable from controls) despite the plasma multimer defect — supports a secretion defect rather than a synthesis defect. CasePreviousTesting: Not genome-wide; targeted VWF gene analysis — Sanger sequencing of all 52 exons and intron-exon boundaries of VWF using published primers, followed by allele-specific cloning (pMD18-T vector) and sequencing to resolve the heterozygous deletion. GenotypingMethod: Direct Sanger sequencing (Applied Biosystems 310 DNA analyzer) of all VWF exons/boundaries; PCR amplification and cloning of individual alleles into pMD18-T vector to confirm and characterize the heterozygous deletion. PreviouslyPublished: NA — first report of this variant/family. Gene: VWF Variant: Novel heterozygous in-frame 6-bp deletion in exon 28, removing residues D1529 and V1530 (ΔD1529V1530) in the VWF A2 domain. Functional studies (HEK293 transfection) showed the mutant is expressed but its secretion is markedly impaired (42±4% of WT in conditioned medium, p<0.01) with intracellular retention (174±29% of WT in cell lysate, p<0.05) and ER colocalization (PDI co-staining); co-transfection with WT VWF reduced WT secretion (61±16% of WT alone, p<0.05), indicating a dominant-negative effect. Classified as a "Group I" type 2A mechanism (impaired intracellular transport/secretion). HGVS: c.4585_4590del (p.Asp1529_Val1530del) — confirmed against the authors' GenBank submission (JN625247) and cross-validated against a real ClinVar-confirmed exon 28 variant ClinVarID: NA CAID: NA gnomAD: NA

    3. IV-3

      Case: Patient IV-3 (son of III-3; first cousin of proband's mother IV-4) DiseaseAssertion: Type 2A VWD, based on low plasma VWF:Ag and activity and lack of plasma HMW VWF multimers. FamilyInfo: Son of III-3 (proband's granduncle); first cousin of IV-4 (proband's mother); part of 5-affected-member pedigree (Fig. 1). ParentalGenotype(s): Father (III-3) heterozygous for the variant, affected. Mother's genotype not reported. CasePresentingHPOs: HP:0012147 (Reduced quantity of VWF; VWF:Ag 19.5 U/dL), HP:0030129 (Impaired VWF:RCo; VWF:Rco 7.6 U/dL), HP:0030132 (Absence of large VWF multimers — plasma), HP:0003645 (Prolonged partial thromboplastin time; APTT 45.2 sec) CaseHPOFreeText: Described only generically as having "abnormal bleedings" / "similar clinical symptoms" — no itemized bleeding symptoms given specifically for this individual.

    1. Case presentation A 27-year-old woman

      Case: Proband, female, 27 years old at report; ethnicity not reported.

      DiseaseAssertion: VWD2A. The authors confirmed type 2A VWD based on VWF:Ac/VWF:Ag ratio <0.7 (excluding types 1C, 2N, and 3), RIPA negative for increased platelet affinity (excluding type 2B), and multimer analysis showing HMWM deletion with IMWM reduction (excluding type 2M).

      FamilyInfo: The patient denied a family history of abnormal bleeding. The father carried VWF c.2281+1G>A and was not diagnosed with VWD (VWF:Ag 61%, VWF:Ac 60.6%, FVIII activity 82%, VWF:Ac/VWF:Ag ratio 0.9). The mother carried VWF c.4654T>A and was diagnosed by the authors as having low VWF per British Committee for Standards in Haematology criteria (VWF:Ag 40%, VWF:Ac 26.6%, FVIII activity 66%, VWF:Ac/VWF:Ag ratio 0.6). Neither parent had a history of abnormal bleeding. Parental laboratory results and genotypes are reported in Table 2.

      ParentalGenotype: Both parents were genotyped. The father was heterozygous for c.2281+1G>A and the mother was heterozygous for c.4654T>A (Table 2). The authors report that the two variants were inherited separately from each parent, establishing compound heterozygosity. Note: Figure 2 shows Sanger sequencing validation for c.2281+1G>A only, confirming the variant in the patient and father and a normal genotype at that locus in the mother. No confirmatory sequencing trace is shown for the maternal c.4654T>A variant; that genotype is reported only in Table 2.

      CaseHPOFreeText: Gingival bleeding persisted for two days after tooth extraction. History of frequent epistaxis and one episode of heavy menorrhagia in 2007 treated with plasma transfusion. ISTH-BAT bleeding score 7 (epistaxis score 1, bleeding after tooth extraction score 2, heavy menorrhagia with plasma transfusion score 4). VWF:Ag 26.2%, VWF:Ac 5.7%, FVIII activity 43%, VWF:Ac/VWF:Ag ratio 0.21. Low-concentration RIPA 23.7% (reference 30.0-70.0%). VWF multimer analysis demonstrated deletion of high-molecular-weight multimers and reduction of intermediate-molecular-weight multimers (Figure 1). Arachidonic acid-induced platelet aggregation was impaired, with a maximal aggregation rate of 14.3%.

      CaseNotHPOs: HP:0003645, HP:0001873 (Prolonged partial thromboplastin time, Thrombocytopenia)

      CaseNotHPOFreeText: APTT 39.2 s (reference 32.0-45.0), platelets 183x10^9/L (reference 125-350), PT 13.6 s (reference 11.0-15.0), and fibrinogen 2.71 g/L (reference 2.0-4.0) were all within reference ranges, as was thrombin time. High-concentration RIPA 52.9% (reference 40.0-80.0), normal. Systemic physical examination unremarkable with no active bleeding on admission. Prior laparoscopic surgery for luteal rupture without a remarkable increase in bleeding. Hemoglobin 125 g/L was marginally below the stated reference range (130-175), although the authors described the complete blood count as normal.

      CasePreviousTesting: Whole-exome sequencing was performed, which is a genome-wide method. No genes other than VWF were reported as tested or implicated. No earlier molecular genetic testing was reported.

      GenotypingMethod: Whole-exome sequencing followed by one-generation (Sanger) sequencing validation, performed on the proband and both parents.

Note: the article gives the protein consequence as p.Phe1152Ile in the Case Presentation and p.Phe1552Ile in the Discussion; these are internally inconsistent. p.Phe1552Ile is correct, as confirmed by HGVS validation and by the ClinGen Allele Registry record (NP_000543.3:p.Phe1552Ile), and is consistent with the stated exon 28 location.

    4. The affected mother (II-3), the two affected daughters (III-3 and III-5) and the affected son (III-1) of the original family with VWD type IIC Miami were available for our study

      Case: Patient II-3, Female, 67 years (as of Dec 2010 follow-up) DiseaseAssertion: VWD type 2A, phenotype IIC ("VWD2AIIC-Miami") — a historically named variant of type 2A characterized by paradoxically elevated VWF:Ag with reduced function; dominantly inherited in this family (unlike classic/most VWD2AIIC, which is recessive). Bleeding score 21 (very high; nv <4). FamilyInfo: Mother of III-1, III-3, and III-5 (all three affected); 4-member, 2-generation pedigree, dominant transmission. ParentalGenotype(s): NA — her own parents not part of this study. 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.
