Venous leg ulceration is a severe complication of chronic venous insufficiency. Despite numerous studies, understanding of the possible mechanisms involved in venous ulceration development remains incomplete. It is assumed that, in addition to well-documented behavioral and/or environmental conditions, as yet poorly defined genetic risk factors may play important roles in chronic wound progression or healing. It is difficult to overestimate the clinical usefulness of genetic screening in the determination of the risk of wound development and/or its healing course. From a pharmacogenomic perspective, genetic screening may aid in the planning of individualized treatment. In addition, the detection of venous ulcer-promoting gene variants may facilitate the decision to introduce prophylaxis or, if necessary, appropriate treatment for venous insufficiency, long before a leg ulcer develops. In addition to significant economic benefits, this approach would reduce the risk of health- and life-threatening conditions. In this review, we focus on several gene mutations/polymorphisms with previously documented significance in leg ulceration pathophysiology, and briefly speculate about possible candidates for further study.
