    Abstract:
    Cardiovascular disease (CVD) remains a major health hazard worldwide. Single nucleotide polymorphisms (SNPs) represent a part of risk factors that contributes to cardiovascular disease. SNP in the coagulation factor V genes have been shown to play a role in the development of cardiovascular disease. Coagulation Factor V is an enzyme cofactor of the coagulation system and contributes to a normal haemostatic balance. The His1299Arg polymorphism in the Factor V gene has been identified and linked to hereditary thrombophilia. The aim of the present study is to determine the prevalence of HR2 haplotype and allele frequency of His1299Arg polymorphism in the Factor V gene among randomly selected healthy individuals from Taif population which belonging to western region of Saudi Arabia. Genotyping of this SNP was carried out via CVD StripAssay, which based on a polymerase chain reaction-reverse hybridization technique. Two hundred healthy unrelated individuals were included in the study. Seventeen out of the studied population (8.5%) had the HR2 haplotype; 14 (7%) were heterozygous (R1/R2), and three (1.5%) were homozygous (R2/R2), with an allelic frequency of 0.05. This is the first report for a Saudi Arabian population that estimates the prevalence of HR2 haplotype and its allele frequencies. In conclusion, the His1299Arg mutant was noticeable within population of western Saudi Arabia. Further larger studies are needed to (1) estimate the prevalence of this mutant among individuals belonging to different KSA locations (2) assess the relative contribution of this mutational event separately and in combination with other thrombophilic polymorphisms in the etiology of cardiovascular disease in KSA.
