Brief description This application aims to confirm our preliminary identification of the first candidate gene as a risk factor for developing venous leg ulceration. Since patients with venous leg ulcers experience pain and psychological consequences including anger and depression, all of which impact negatively on quality of life, active prevention of ulceration will have significant lifestyle and financial benefits. Venous leg ulcers occur in patients who have venous disease, in particular in patients with previous deep vein thrombosis. However, not all patients with a deep vein thrombosis or other forms of venous disease will go on to develop a venous ulcer. Our preliminary results show that patients with a venous ulcer have a greater frequency of this gene than healthy controls without venous ulcers, and suggest that patients with the candidate gene have a greater risk of developing venous ulceration. In this study we aim to determine whether the gene itself contributes to ulcer susceptibility or whether it is just a marker of that susceptibility. We can do this by assessing related genes and the levels of the protein produced by this gene. In this study we also aim to assess whether patients with a proven deep vein thrombosis are more likely to develop venous ulceration if they have the candidate gene. These studies have the potential to lead to the development of a diagnostic screening test for use in patients with venous disease, to assess the likelihood of developing leg ulceration. This will enable more active treatment to prevent leg ulceration. If this gene contributes to ulcer susceptibility new specific treatments may be developed for ulcer management and prevention.
