Furthermore, through a massive research effort over the last two decades focusing on epigenetic modifications in epistasis and/or gene-environment interactions as well as attempts to characterize the impacts of APP on thrombosis and cancer related to LND [109]–[147] are likely to emerge in the near future and will help to improve the prophylactic and treatment strategies for LND, VTE as well as cancer. The gene discussed is APP; the disease is deep vein thrombosis.
