INTRODUCTION: Von Willebrand disease (VWD) is an autosomal congenital bleeding syndrome that was described as being the most widespread genetic condition among men. In Saudi Arabia, the genotyping of the VWF gene is necessary to establish a diagnosis procedure for VWD.
AIM: The current research, however, attempted to evaluate the phenotypic-genotypic association of the Von Willebrand factor (exon 18 and 20) gene in healthy subjects to establish effective molecular diagnostic strategies.
METHODS: This was a cross-sectional retrospective included 100 healthy people who have been chosen from King Fahad University Hospital. Whole blood samples were collected from all individuals, as well as the laboratory analysis was done using automatic analyzers for; platelet count, ABO blood group and coagulation parameters. DNA Sanger sequencing has been used to sequestrate the full exons 18 and 20.
RESULTS: In exon 18 of healthy people, three unusual sequence variations (1 missense and 2 synonymous; rs775479826, rs1286572448 and rs369828268) compared to other recorded VWF variations (3 missense and 1 synonymous; c.2365A > G, c.2385T > C, c.2344C > T and c.2340C > G). But in exon 20 only 1 synonymous novel (rs113240752) 1 registered VWF variations in missense (c.2555G > A) were identified.
CONCLUSION: The present variants found on those participates could be a realistic approach to detect mutation in the VWF gene to illustrating the relationship of phenotypic and genetic abnormalities variables may lead to determining the functional effect in mutations specific to the Saudi people that can be used to develop a diagnostic tool for VWD in KSA.
