WebWhat type of mutation is Hemophilia? Hemophilia is inherited in an X-linked recessive pattern.

WebHemophilia A is a disorder characterized by congenital deficiency of FVIII. Almost all patients with hemophilia A have F8 gene mutations. Because F8 is located on the X chromosome, hemophilia A follows an X-linked inheritance pattern. As a result, most affected individuals are male. WebHemophilia A and B are rare X-linked bleeding disorders caused by mutations in the genes encoding coagulation factor VIII (FVIII) and factor IX (FIX). Hemophilia A (HA) is more common than hemophilia B (HB), with a prevalence of one in 5,000 male live births compared to one in 30,000, respectively. 1
