Résumé
Genetic variations influence the Von Willebrand Factor plasma level and function. This study aims to evaluate the frequency and clinical phenotype effects of eight single nucleotide polymorphism candidates in four genes (VWF, STXBP5, CLEC4M, and ABO) in Iranian patients with VWD type 1. The study recruited 50 patients with VWD type 1 and 100 healthy individuals. The demographic data from all participants were collected, and the High-Resolution Melting technique was used to determine the frequency of specific single nucleotide polymorphisms. Bleeding scores were also obtained from all patients to assess how these genetic variations might affect the severity of their bleeding symptoms. The study found notable variations in the occurrence of certain SNPs (rs7853989 and rs8176743 for ABO gene and rs1063856 and rs1063857 for VWF gene) between the control group and the patients. Additionally, the study discovered that two SNPs (rs868875 for CLEC4M gene and rs9390459 for STXBP5 gene) were significantly linked to the severity of bleeding, and two others (rs868875 for CLEC4M gene and rs8176746 for ABO gene) were associated with reduced levels of VWF antigen in the patients. According to this study, the above-selected SNPs can cause variations in VWF plasma levels in patients with VWD type 1. Furthermore, the effects of SNPs on bleeding phenotype prove the role of these SNPs in the severity of bleeding manifestations in patients.

BACKGROUND
BACKGROUND
Genetic variations influence the Von Willebrand Factor plasma level and function. This study aims to evaluate the frequency and clinical phenotype effects of eight single nucleotide polymorphism candidates in four genes (VWF, STXBP5, CLEC4M, and ABO) in Iranian patients with VWD type 1.
METHOD
METHODS
The study recruited 50 patients with VWD type 1 and 100 healthy individuals. The demographic data from all participants were collected, and the High-Resolution Melting technique was used to determine the frequency of specific single nucleotide polymorphisms. Bleeding scores were also obtained from all patients to assess how these genetic variations might affect the severity of their bleeding symptoms.
RESULTS
RESULTS
The study found notable variations in the occurrence of certain SNPs (rs7853989 and rs8176743 for ABO gene and rs1063856 and rs1063857 for VWF gene) between the control group and the patients. Additionally, the study discovered that two SNPs (rs868875 for CLEC4M gene and rs9390459 for STXBP5 gene) were significantly linked to the severity of bleeding, and two others (rs868875 for CLEC4M gene and rs8176746 for ABO gene) were associated with reduced levels of VWF antigen in the patients.
CONCLUSION
CONCLUSIONS
According to this study, the above-selected SNPs can cause variations in VWF plasma levels in patients with VWD type 1. Furthermore, the effects of SNPs on bleeding phenotype prove the role of these SNPs in the severity of bleeding manifestations in patients.
