WebHemophilia is often inherited, meaning genetics play a strong role in who develops hemophilia. But in some cases, hemophilia is acquired. 2 In most cases, a mutation in the genes responsible for making clotting factors causes hemophilia. 2 The genes for factors VIII and IX are only found on the X chromosome, while the factor XI gene is found on … WebHemophilia B also called factor IX (FIX) deficiency or Christmas disease which is a recessive X-linked genetic disorder involving a lack of functional clotting Factor IX.
