      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).

      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).

    1. In FVIII-binding assays, vWF-W19 and vWF-Q54 show maximal binding that is 79% and 75% of wt vWF, respectively (Fig 6). Maximal binding for FVIII by vWF.3 was 52% of wt vWF. Added together, the percent reduction in binding for vWF-W19 and vWF-Q54 is nearly equal to the percent reduction of binding shown by vWF.3 (46% v 48%). These mutations also show an additive effect on the concentration of FVIII at which half-maximal binding occurs.

      ExperimentName: Factor VIII binding assays for variants exogenously expressed in COS-7 cells

      NonPatientCell: COS-7 cell line (CLO:0002597, EFO:0002009)

      GeneFunction: GO:0005515 (protein binding, specifically to Factor VIII)

      GeneAlteration: Site-directed mutagenesis was used to introduce a mutation encoding "His54Gln" (corresponding to the p.His817Gln substitution from the variant) into the mature (cleaved) VWF protein.

      FunctionalEvidence: The variant did not disrupt multimer formation (Figure 5) but reduced Factor VIII binding to 75% of wild-type levels (Figure 6). In combination with another missense mutation in cis that reduced Factor VIII binding by an additional 21-23%, and a frameshift mutation in trans predicted to cause the absence of a gene product, the variant appears likely to be contributing to pathogenicity.

      FAVariants: A construct equivalent to the c.2451T>A (p.His817Gln) variant was used (ClinVar:100224), although it expressed the proteolytically processed version of the protein product and referred to the variant as "His54Gln".

      PMID: 23690449

      Gene: VWF

      HGNC: 12726

      Disease: von Willebrand Disease Type 2N

      MONDO: 0015631

      InheritancePattern: Autosomal Recessive

      Prevalence: Various sources (PMID: 28847738, PMID:19809303, PMID:29115006) can be combined to estimate the prevalence of VWD Type 2N between 1:15,000 and 1:80,000.

      Penetrance: VWD type 2 is fully penetrant / nearly fully penetrant for most pathogenic variants.

    1. Wild type and several naturally occurring type 2N VWF variants (H817Q, R854Q+T789A, R782W, and R782W+H817Q) or a hereditary persistance of propeptide (HPP) variant (Fig. 1A) were constructed and expressed transiently in human embryonic kidney 293T cells.

      ExperimentName: Transient expression of VWD type 2N variants in 293T cells

      NonPatientCell: human embryonic kidney 293T cells (EFO:0001082)

      GeneFunction: GO:0005515 (protein binding, specifically to Factor VIII)

      GeneAlteration: A mutation encoding p.His817Gln was introduced into a construct for exogenous expression of the VWF protein.

      FunctionalEvidence: The variant protein exhibited a mild defect in FVIII binding relative to the wild-type (less severe than other VWD type 2N variants) (Figure 1C). Because of the defect in FVIII interaction, the variant also exhibits mildly reduced cleavage by ADAMTS13 (Figures 1F, 1G, and 1H).

      FAVariants: A construct equivalent to the c.2451T>A (p.His817Gln) variant was used (ClinVar:100224).

    1. p.(Val510 = ) variant

      PMID: 33134807

      Gene: VWF

      HGNCID:12726

      Case: Female patient from the French Caribbean island of Martinique

      DiseaseAssertion: VWF Type 3

      FamilyInfo: The proband had a combination of two variants p.(Val510+) and p.(Pro21452145Thrfs*5) in a heterozygous state. Her biological profile indicated VWD3: VWF:Ag = 1 to 5%, VWF:RCo = 5%, FVIII:C = 2 to 3%, VWFpp = 6%, and a total absence of multimers assessed by electrophoresis. She was usually treated with plasma-derived VWF concentrates. Interestingly, the VWFpp level in this patient was higher than expected for typical VWD3. The sister who died from a nonhemorrhagic cause had the same clinical-biological profile.

      ParentalGenotype(s): The mother had a normal biological assessment and was asymptomatic without any bleeding. Sequencing of the mother's VWF gene revealed a single variant on exon 37: resulting in the nucleotide change c.6432dup / a.a. change p.(Pro2145THRfs*5) which results in a stop codon. This molecular abnormality favors VWD3, even though the mother is asymptomatic. The father experienced excessive bleeding only as a result of trauma or surgery. Sequencing of the father's VWF gene led to the identification of one potential causative variant: p.(Val510 = ), on exon 13 with a nucleotide change c.1530G>A. A second sister of the proband has a clinical and biological phenotype similar to that of her father.

      CaseHPOFreeText: The proband presented with severe hemorrhagic manifestations.

      CaseSubsequentTesting:N/A

      GenotypingMethod:NGS

      PreviouslyPublished: No

      SupplementalData: The prediction softwares used (SpliceSiteFinder-like, MaxEntScan, GeneSplicer, NSPLICE, ESEFinder, RESCUE-ESE, and EX-SKIP) regarding c.1530G > A (p.(Val510 = )) interpreted the appearance of a donor site at 6 base pairs at the end of exon 13 which could potentially alter splicing. This synonymous mutation could therefore have an effect on VWF messenger ribonucleic acid processing, causing a shift in the reading frame and the appearance of a termination codon deletion of two codons. The ACMG predicted that this variant would probably be pathogenic.

      VariantEvidence: An additional 21 patients from Martinique were identified with the p.(Val510=) variant. Median age was 63 years (interquartile range [IQR], 45–77) and 65% were female. The striking feature in these patients was a significantly increased VWFpp/VWF:Ag ratio with a median of 5.62 (IQR, 4.36–6,14). This ratio could be calculated only for the 14 patients for whom the VWFpp level was measured. An increased VWFpp/VWF:Ag ratio (> 2.2) is indicative of an accelerated clearance of VWF. Addition testing in four patients involved DDAVP infusion compared to a patient with a VWD1 mutation that does not cause a clearance defect. The results showed accelerated VWF clearance compared to the control. The author propose to classify patient with the p.(Val510=) variant as Type 1C, a rare subtype that removes VWF more quickly than normal in the blood.

    1. The 26-year-old female IP is diagnosed to have type 3 VWD, due to no detectable VWF in plasma (VWF antigen (VWF:Ag) level < 4%).

      Case: Index Patient (IP), Female, 26 years old; described as from a genetically isolated population (not further specified), consistent with elevated homozygosity rates in that population. DiseaseAssertion: Type 3 VWD, confirmed by VWF:Ag <4 IU/dL (virtual absence of VWF). FamilyInfo: NA — no relatives' bleeding history or genotype reported ParentalGenotype(s): NA (not tested/not reported) CasePresentingHPOs: HP:0000421 (Epistaxis — frequent nosebleeds), HP:0000132 (Menorrhagia — heavy, prolonged, led to iron-deficiency anemia), HP:0001934 (Persistent bleeding after trauma — bleeding following injury), HP:0012147 (Reduced quantity of VWF; VWF:Ag <4 IU/dL), HP:0030129 (Impaired VWF:RCo-type activity; VWF:GPIbM <4 IU/dL) CaseHPOFreeText: Easy bruising (no matching HPO code in the approved list); FVIII:C 2.0 IU/dL (nv 70–157); referred to Hemophilia Centre at age 1 for bleeding complications; declined recommended lifelong prophylaxis due to injection discomfort, later underwent prophylaxis with plasma-derived VWF/FVIII concentrates and on-demand treatment (tranexamic acid, oral contraceptives, replacement therapy). Supporting functional evidence from patient-derived endothelial colony-forming cells (ECFCs): virtual absence of VWF mRNA (RQ ~0.04–0.05 vs. 1.00 in healthy controls, across 4 primer/probe sets); VWF secretion into ECFC medium 6.2% ± 0.4% of healthy controls (p<0.0001); near-total absence of Weibel-Palade bodies on immunofluorescence (only 1–3 small WPBs seen in some cells vs. normal stick-shaped WPBs in controls); altered intracellular trafficking of angiopoietin-2 (WPB inflammatory cargo) in the absence of WPBs. CaseNOTHPOs: NA CaseNOTHPOFreeText: NA CasePreviousTesting: Routine testing (Sanger sequencing of coding exons, ~50 bp flanking intronic regions, promoter, 5'/3'-UTR, plus MLPA) was negative — patient was "mutation-negative" prior to this study. Not genome-wide; targeted to VWF only, but comprehensive: this study's NGS covered the entire 176 kb VWF locus (all 52 exons, full intronic regions, promoter) at 30x coverage, going well beyond standard exon+flanking-intron approaches specifically to find deep intronic variants. GenotypingMethod: Illumina NovaSeq 6000 NGS (2×150 bp reads) of the whole VWF genomic region; variant annotation via Ensembl VEP with SpliceAI, PolyPhen-2, SIFT; splice effect independently confirmed with Neural Network Splicing, ASSP, and MaxEnt/HSF prediction tools. Functional validation via patient-derived ECFCs: RT-qPCR of VWF mRNA (4 primer/probe sets), cDNA sequencing, VWF:Ag ELISA of ECFC secretion, immunofluorescence microscopy, and whole-transcriptome RNA-seq. PreviouslyPublished: NA — no indication this patient was reported elsewhere; paper explicitly frames this variant/mechanism as a first report. Gene: VWF Variant: Novel homozygous deep intronic variant, intron 8, creating a new donor splice site that outcompetes the native donor site, causing inclusion of a 118-bp pseudoexon, frameshift, premature stop codon, and nonsense-mediated decay of the transcript. HGVS: NM_000552.5:c.997+118T>G (confirmed via ClinGen Allele Registry Community Standard Title; not explicitly stated in the paper's main text, which only gives cDNA/genomic coordinates without a transcript version). Genomic: g.6073501A>C (GRCh38/hg38; note the T>G/A>C discrepancy reflects VWF being transcribed from the minus strand of chr12). ClinVarID: NA CAID: CA3275979827 gnomAD: NA

      PMID 16322474

      Notes Recombinant full length p.Ile1628Thr expressed in HEK293 and purified from growth media was NOT digested by recombinant ADAMTS13 in non-denaturing conditions (Table 1, Fig 5a). However, the the A1-A3 p.Ile1628Thr truncations were digested by ADAMTS13 in non-denaturing conditions while WT recombinant VWF truncations were not (Fig 6).
