How to Say It: Kron-ik gran-u-lo-ma-tus disease
Chronic granulomatous disease (CGD) is a rare genetic problem. White blood cells called phagocytes are not able to kill some types of bacteria and fungi. This can lead to frequent and deadly infections.
CGD is caused by one of five faulty genes. One type of CGD is x-linked, meaning the faulty gene is passed from mother to son. The other four types are recessive. This means one of the faulty genes is passed from each parent to their child.
The x-linked form of CGD is more common in males.
Symptoms usually start in early childhood. Often, a baby will have a history of frequent infections that do not respond to treatment.
Problems may be:
Bacterial Skin Infection

The doctor will ask about your symptoms and health history. A physical exam will be done.
A blood test or tissue biopsy will be done to look for signs of CGD or the faulty gene.
The goal of treatment is to manage symptoms. Choices are:
A stem cell transplant may be done. It may cure the disease in some people. It is not right for everyone.
There are no known ways to prevent this health problem.
