Factor X: A coagulation factor, a substance in blood essential to the normal clotting process. Production of factor X takes place in the liver and requires vitamin K . The gene for factor X is located on chromosome 13 and is in band 13q34.

The "X" in factor X is the Roman numeral "ten." (All numbered coagulation factors bear Roman numerals.) Factor X became known because of a genetic condition in which the factor is lacking.

Factor X deficiency is inherited as an autosomal recessive trait manifest by prolonged nose bleeds, gastrointestinal hemorrhage , menorrhagia (abnormally heavy menstrual bleeding), hematuria (blood in the urine), and hemarthrosis (bleeding into joints). Pregnancy in women with factor X deficiency is often associated with adverse fetal outcomes ( recurrent spontaneous abortion , placental abruption , and premature birth ).

Factor X is also called Stuart-Prower factor because Mr. Stuart and Miss Prower were the first persons shown to have deficiency of this factor.
