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).

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).

      Note: The article assumed that 5053+1G→A causes a frameshift mutation. No potential splice site mutation was confirmed at the mRNA level; “Splice Site Prediction program” found all mutations likely to disrupt normal splicing. No possible splice site mutation could be identified on 100 chromosomes from a group of 50 normal subjects with same genetic background as patients, excluding the possibility that these mutations represent common polymorphisms.

      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.

      CasePreviousTesting: Nucleotide sequences of beta3 cDNA and beta3 genomic DNA were analyzed by the dye terminator cycle sequencing method, in addition the nucleotide sequences of alphaIIbeta cDNA were anlso analyzed based on the published sequence of alphaIIbeta

    1. 3-month-old male

      Case#: 3 month old male neonate

      Disease: Glazmann's Thrombasthenia

      CasePresentingHPOs: HP:0000967, HP:0007420, HP:0003010

      Petechiae, Spontaneous hematomas, Prolonged bleeding time

      PlateletAgreggation: Impaired in response to all stimuli including adenine diphosphate (2%), collagen (24%), arachidonic acid (13%), and epinephrine (13%). In contrast, platelet aggregation to ristocetine was almost normal (67%; lower limit of normal is 70%).

      ExpressionEvidence: Flow Cytometry analysis showed reduced αIIbβ3 expression on patient platelets

      FamilyInfo: Pedigree Figure 1. Homozygous HPA-1aa father and heterozygous HPA-1ab mother indicating that both HPA-1a alleles inherited to the GT son are defective carrying either Cys460Trp or Trp11Arg mutation.

      FunctionalEvidence: Flow cytometry analysis of wild-type (Cys460) and mutant (Trp460) expressed on HEK293 cells showed equal surface expression of αIIbβ3 and αvβ3. Immunoblotting analysis (Figure 2B) showed that the mutant β3 migrated slightly slower in comparison with wild-type β3 isoform, indicating that the disruption of one disulfide bond due to Cys460Trp mutation alters the secondary structure of integrin αIIbβ3. However, evidence that Csy460Trp mutation alters the binding of some mAbs against HPA-1a.
