Moderately severe haemophilia A – http://id.who.int/icd/entity/1491982251

Moderately severe haemophilia A is a form of haemophilia A (see this term) characterised by factor VIII deficiency leading to abnormal bleeding as a result of minor injuries, or following surgery or tooth extraction. Moderately severe haemophilia A accounts for around 20% of all cases of haemophilia A. The biological activity of factor VIII is between 1% and 5%. Spontaneous haemorrhages are rare. Transmission is X-linked recessive and the disorder is caused by mutations in the F8 gene (Xq28) encoding coagulation factor VIII.
