CasePreviousTesting:

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). In both strategies, the entire VWF, encompassing all 52 exons, intron/exon boundaries, and promoter regions, was analyzed.
