      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: 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).

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

      CasePresentingHPOs:BAT score=16, Arterial thrombosis=ischemic stroke, FVIII:C*=1, VWF:Ag=3, Proein S:58, Protein C:100, antithrombin III=106, activated protein C resistance:2.9. 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.

    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
