GenotypingMethod: Sequence variations in the VWF were identified through direct sequencing, while the detection of large rearrangements utilized the multiplex ligation-dependent probe amplification (MLPA) technique or assessed copy number variations (CNVs). Sanger sequencing methodology was applied for VWF analysis in patients investigated prior to 2016 (approximately 14% of IPs), whereas next-generation sequencing (NGS) was employed for the analysis of VWF in patients inspected from 2017 onwards (about 86% of IPs).

FamilyInfo: Mother is unaffected carrier of F8 Asn2129Ser. The VWF deletion of exons 33-34 segregates in 5 other affected male family members including the father and a full brother of IP-6. The patient’s father displayed a significant decrease in VWF:Ag and VWF:RCo, 13% and 7%, respectively, FVIII: C of 18.5% and the VWF:RCo/VWF:Ag ratio of 0.5 pointing out to type 2 VWD.

CasePreviousTesting: Direct sequencing of exons 2–52 including exon/intron boundaries of the VWF gene

GenotypingMethod: multiple ligation‐dependent probe amplification (MLPA; using kit P011 and P012; MRC Holland, Amsterdam, the Netherlands) according to the manufacturer’s instructions. The PCR products were run on an ABI PRISM 3130XL sequencer with the GeneScan 500 LIZ size standard and analyzed using GeneMapper Software 5.0 (Applied Biosystems, Darmstadt, Germany). Dosage analysis based on a comparison between deleted and reference wild‐type DNA samples was performed using the Excel‐based software Coffalyser V9.4 (MRC Holland).

CasePreviousTesting:

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).
