Mild haemophilia A – http://id.who.int/icd/entity/1275649978

Mild haemophilia A is a form of haemophilia A (see this term) characterised by a small deficiency of factor VIII leading to abnormal bleeding as a result of minor injuries, or following surgery or tooth extraction. Mild haemophilia A accounts for around 40% of all cases of haemophilia A. The biological activity of factor VIII is between 5 and 40%. Spontaneous haemorrhages do not occur. Transmission is X-linked recessive and the disorder is caused by mutations in the F8 gene (Xq28) encoding coagulation factor VIII.
