Preferred Label : Factors VIII, ix and XI, combined deficiency of;

CISMeF acronym : FMFD V; MCFD5;

Type : Other, mainly phenotypes with suspected mendelian basis;

Alternative titles and symbols : Familial multiple coagulation factor deficiency V; Multiple coagulation factor deficiency V; MCFD5; FMFD V;

Description : Soff et al. (1981) reported 4 families with combined deficiency of coagulation factors VIII, IX and XI. Family 1 had several persons with dislocations, e.g., of patella and hips, and several who had possible hemarthrosis related to trauma. Other probands were referred because of the finding of prolonged partial thromboplastin time (PTT) on preoperative testing. Two generations were affected in 2 families, and males and females had similar procoagulant levels and histories of abnormal hemostasis. No male-to-male transmission was observed. The pathogenesis of FMFD V is unknown. The 3 factors are biochemically and functionally different and the possibility of a common precursor or subunit is highly unlikely. Possibly a common regulator is deficient. Angelopoulos et al. (1964) described combined deficiency of factors;

Inheritance : Autosomal dominant;
