It was the aim of this study to report a new point mutation in the clotting factor V gene in the general Arab population.
The HR2 haplotype was tested in 288 Arabs living in Kuwait--188 patients with venous thromboembolic disorders (VTE) and 100 healthy subjects--using polymerase chain reaction and restriction fragment length polymorphism techniques. The presence of the new mutation was verified by DNA sequencing.
Two (1.06%) VTE patients had guanine instead of the wild-type adenine at nucleotide number 3935 (A3935G) of the factor V gene. This mutation caused a histidine to arginine change in amino acid number 1254 of the factor V molecule. The new mutation is termed 'factor V Kuwait' (His1254Arg) and was absent in the 100 healthy subjects.
It appears that factor V Kuwait could be a risk factor for developing VTE in Arabs. A larger study is needed to confirm this observation.
