FXI plays an important role in the amplification of the initial coagulation response via a positive feedback mechanism for the generation of additional thrombin [1,2,3,4]. Congenital FXI deficiency is characterized by decreased levels or activity of FXI in the plasma and may cause an inherited bleeding disorder. The FXI gene is located on 4q34- 35 and consists of 15 exons.eninfo:eu-repo/semantics/openAccessFactor XiMutationFamilyLetter351798028947414WOS:0004265722000162-s2.0-85042436343Q410.4274/tjh.2017.0140Q3267216
