Rare inherited coagulation disorders due to the deficiency or dysfunction of coagulation factors have until recently received less clinical attention than hemophilias and von Willebrand disease. This situation has changed in the last decades, mainly due to therapeutic progress with the availability of more and safer products for replacement therapy produced by plasma fractionation or recombinant DNA technology. This narrative review, based on the latest literature and expert opinion, emphasizes the progress achieved for each of the rare deficiencies, mentions the still unmet therapeutic needs, and sketches the perspectives for further progress.
Rare inherited coagulation disorders have experienced much progress regarding treatment.
Single-factor plasmatic or recombinant products are available for factor (F)VII, FX, FXI, and FXIII deficiencies.
However, FV and prothrombin deficiencies are still missing a specific treatment agent.
Coagulation rebalancing agents promise to fulfill the unmet needs of these patients.
