Abstract

Factor XI deficiency is a very rare autosomal recessive coagulation factor deficiency, comprising 1/million in ethnic groups other than Ashkenazi Jews. The clinical manifestations are extremely variable, and generally milder than those of hemophilia A and B. We describe herewith 3 children with factor XI deficiency, who were found to have prolonged aPTT in routine laboratory studies, or in evaluation of intermittent epistaxis.
