Introduction Congenital factor X (FX) deficiency is a rare bleeding disorder inherited as an autosomal recessive trait with an incidence of 1 :500 000-1 000 000. A total or partial deficiency of FX causes an impairment of clot formation, leading to a haemorrhagic disease, which manifests with bleeding symptoms of different severity, also unprovoked.
