The von Willebrand Factor (vWF) gene located on Chromosome 12 spans ~ 180 kilobases with 52 exons. Changes in the vWF gene could alter VWF biosynthesis, secretion, clearance, and adhesion activity. Single nucleotide polymorphisms (SNPs) in exons, 5′ regulatory region, and introns are also reported to influence levels of vWF in healthy subjects. Some of these vWF SNPs are associated with an elevated risk for thrombosis and may be causally associated with coronary heart disease. The objective of this work was to detect the association between-1185A/G vWF gene polymorphism and CHD in Gaza strip. We conducted case-control study included 126 samples comprised 85 CHD patients and 41 control subjects. Questionnaire interview was applied. Blood samples were collected in EDTA tube for ABO blood grouping and DNA extraction. Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) use to detect – 1185A/G polymorphism. The vWF -1185A/G genotype was the most common in the control and the CHD groups. The frequencies of vWF -1185 alleles in the CHD subjects were 0.541 for A and 0.459 for G. These frequencies are comparable to those found in the control group which were 0.622 for A and 0.378 for G. No statistically significant differences in vWF-1185 genotypes were found between the patients and the control groups. Moreover, there was no significant difference between the vWF-1185 polymorphism: gender, blood group, hypertension and diabetic in case and controls. However, there was a significant difference between the CHD: age, physical activity and education. To our knowledge, this is the first study in Gaza Strip investigating the relation between vWF-1185 A/G polymorphism and CHD. Further investigations are needed to link other genetic factors to CHD.
