      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).

      FamilyInfo: The phenotypes of the affected propositus, the two unaffected parents, and the unaffected sibling are documented in Table I and Figure 1, while the family relationsihps and genotypes are not shown but described.

      ParentalGenotype(s): The parental genotypes are negative for the variant, indicating that the variant is likely de novo in the proband.

      CasePreviousTesting: Because of the detailed clinical phenotype, genotyping was limited to the VWF locus alone.

      GenotypingMethod: Genotyping consisted of PCR amplification and Sanger sequencing of the 52 exons of the VWF gene, as well as linkage analysis using four STRs located within the VWF locus.

    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".

    1. type 3‐VWD patient

      Case:44‐year‐old male patient

      DiseaseAssertion:type 3‐VWD patient

      FamilyInfo:positive family hsiory: The proband and his sister both had low FVIII:C (1 IU/dL) and VWF:Ag (3 IU/dL) levels, confirming the diagnosis of type 3 VWD. His father had nearly normal levels of FVIII:C (58 IU/dL) and VWF:Ag (57 IU/dL). His daughter had type 1 VWD with decreased FVIII:C (46 IU/dL) and VWF:Ag (19 IU/dL)., NGS identified a heterozygous VWF c.2328delT (p.A778Lfs*23) frame shift mutation only in the proband and his sister

      ParentalGenotype(s):VWF missense mutation, c.6521G > T (p.C2174F), was found heterozygous in father, but mother not tested

CaseHPOFreeRext: Complete blood count showed normocytic anemia (hemoglobin 74 g/L), normal white cell (and differential), and platelet counts. He had prolonged activated partial thromboplastin time (APTT) (89.4 s (s) [reference range (RR), 28.0–44.0 s]) with greatly decreased FVIII:C (1 IU/dL) and VWF:Ag (3 IU/dL) (Table 1). Abdominal ultrasound scanning revealed fatty liver, normal gallbladder, spleen, pancreas, and kidneys. Four hundred ml of virus inactivated fresh frozen plasma (FFP) was transfused, and his VWF:Ag increased to 6 IU/dL. On Day 2 after admission, the patient abruptly experienced numbness and weakness in his right limb.
