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).
