Factor X
Factor X deficiency is an inherited bleeding disorder that is caused by a problem with factor X. Reasons behind this include: the body produces less factor X than it should, the factor X is not working properly, or the clotting reaction is blocked prematurely and the blood clot does not form.
Factor X deficiency is an autosomal recessive disorder, which means that both parents must carry the defective gene in order to pass it on to their child. This also means that the disorder affects both males and females. Factor X deficiency is one of the rarest inherited clotting disorders, but like all autosomal recessive disorders, it is found more frequently in areas of the world where marriage between close relatives is common.
Factor X deficiency may also be inherited with other factor deficiencies.
