An important gene associated with Livedoid Vasculitis is F2 (Coagulation Factor II, Thrombin), and among its related pathways/superpathways are Response to elevated platelet cytosolic Ca2+ and Regulation of Insulin-like Growth Factor (IGF) transport and uptake by Insulin-like Growth Factor Binding Proteins (IGFBPs). Affiliated tissues include skin and endothelial, and related phenotypes are skin ulcer and abnormality of the lower limb
