This can cause swelling and pain or tightness in the joints it often affects the knees, elbows, and ankles. This type is caused by a lack or decrease of clotting factor IX. This type is caused by a lack or decrease of clotting factor VIII. There are several different types of hemophilia.

Get tested regularly for blood-borne infections.

Exercise and maintain a healthy weight to protect your joints.

Get vaccinated-Hepatitis A and B are preventable.

Get an annual comprehensive checkup at a hemophilia treatment center.

Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain.

Bleeding in the head and sometimes in the brain which can cause long term problems, such as seizures and paralysis.

Bleeding within joints that can lead to chronic joint disease and pain.

However, about one-third of the time, the baby with hemophilia is the first one in the family to be affected with a mutation in the gene for the clotting factor. Sometimes, there are carrier females in the family, but no affected boys, just by chance. Learn more about the inheritance pattern for hemophilia.Įven though hemophilia runs in families, some families have no prior history of family members with hemophilia. In addition, she can pass the affected X chromosome with the clotting factor gene mutation on to her children. Sometimes a female who is a carrier can have symptoms of hemophilia. In these females, bleeding symptoms may be similar to males with hemophilia.Ī female with one affected X chromosome is a “carrier” of hemophilia. In such cases both X chromosomes are affected or one is affected and the other is missing or inactive. Females can also have hemophilia, but this is much rarer. Thus, males can have a disease like hemophilia if they inherit an affected X chromosome that has a mutation in either the factor VIII or factor IX gene. This means that males only have one copy of most of the genes on the X chromosome, whereas females have 2 copies. The X chromosome contains many genes that are not present on the Y chromosome. Females inherit one X chromosome from each parent. Males inherit the X chromosome from their mothers and the Y chromosome from their fathers.

Males have one X and one Y chromosome (XY) and females have two X chromosomes (XX). These genes are located on the X chromosome. This change or mutation can prevent the clotting protein from working properly or to be missing altogether. Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot. This condition often resolves with appropriate treatment. The majority of cases involve middle-aged or elderly people, or young women who have recently given birth or are in the later stages of pregnancy. In rare cases, a person can develop hemophilia later in life. The lower the amount of the factor, the more likely it is that bleeding will occur which can lead to serious health problems. The severity of hemophilia that a person has is determined by the amount of factor in the blood. People with hemophilia have low levels of either factor VIII (8) or factor IX (9). This can lead to spontaneous bleeding as well as bleeding following injuries or surgery. Blood contains many proteins called clotting factors that can help to stop bleeding. Hemophilia is usually an inherited bleeding disorder in which the blood does not clot properly.
