Haemophilia is a group of hereditary genetic disorders in which the blood clotting mechanism is impaired. Haemophilia A (clotting factor VIII deficiency) is the most common form of the disorder, occurring at about 1 in 5,000–10,000 male births.Haemophilia B (factor IX deficiency) occurs at about 1 in about 20,000–34,000 male births.
Haemophilia is a X linked ressesive disorder, which is more likely to occur in males rather than females.Females are almost exclusively asymptomatic carriers of the disorder. Female carriers may inherit the defective gene from either their mother, father, or it may be a new mutation. Only under rare circumstances do females actually have haemophilia.Severe complications of Haemophilia are Deep internal bleeding,Joint damage from hemarthrosis,Transfusion transmitted infection and Intracranial hemorrhage.
