Rare Coagulation Factor Deficiencies Associated with Congenital Abnormalities

Abstract

Baris Malbora, Murat Derbent and Namik Ozbek

Among bleeding disorders, hemophilia A, hemophilia B and von Willebrand diseases are the most commonly occurring, whereas deficiencies of other coagulation factors are rare worldwide. Unlike hemophilias, which are X-chromosome linked disorders, the inheritance pattern of the rare coagulation factor deficiencies is generally autosomal recessive. In literature, association of these factor deficiencies and congenital abnormalities are especially rare. In this study, we present our cases having both rare factor deficiencies and congenital abnormalities, including Cenani-Lenz syndrome and Duane retraction syndrome.
