COAGULATION DISORDERS

Coagulation defects (clotting factor deficiencies) may be inherited or acquired (Table 19.24), mainly including Hemophilia A and B-both being X-linked recessive, almost always seen in males only. Hemophilia C (_fXI deficiency), parahemophilia (_fV deficiency) and other coagulation defects are usually autosomal recessive and produce minor hemorrhagic disease.
