Definition

Chronic granulomatous disease develops when a specific gene from both parents passes to the child. This gene causes abnormal cells to develop in the immune system. The abnormal cells are called phagocytic cells. They normally kill bacteria. With this disease, these cells cannot work properly. As a result, the body can not fight some types of bacteria. It also makes infections likely to return.

The increased risk of infections can lead to premature death. Repeated lung infections are often the cause of death with this disease. Preventative care and treatment can help to reduce and temporarily control infections.

CGD is a rare condition.

Causes

The disease is usually caused by a recessive gene. This means two of these defective genes have to be present for the disease to develop. This gene is carried on the X chromosome. Both parents must have the gene.

Risk Factors

The following factors increase your chance of developing CGD:

• Parents who have the recessive trait
• Being female

Symptoms

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done.

Tests may include the following:

Treatment

Talk with your doctor about the best plan for you. Treatment options include:

Prevention

CGD is an inherited disease. There are no preventive steps to reduce the risk of being born with the disease. Genetic counseling may be helpful. It can be used to detect carrier status in woman. Early diagnosis is vital. It will allow for early treatment. The bone marrow transplant donor search can also be started.
