The prevalence of heterozygous F12 mutations in Chinese population and its relevance to incidents of thrombosis

Background The contribution of moderate coagulation factor XII (FXII) deficiency to development of thromboembolism is still undetermined. We have tried to show the relevance of FXII deficiency to incidences of venous thrombosis by exploring the prevalence of F12 gene mutations in Chinese patients with thrombotic disorders.
