D72.0: Genetic anomalies of leukocytes

Blood is made up of a liquid part and different blood cells, among other things. The blood cells include the red blood cells, the white blood cells and the platelets. White blood cells are part of the body’s immune system. They fight pathogens.

There are various types of white blood cell. Some of your white blood cells look changed. This can be seen under the microscope, for example. The disease is congenital, which means you were born with it.

The changed white blood cells may not work properly as a result. However, the body may also no longer be able to fight off some of the pathogens properly, causing you to get sick more quickly, for example. Other diseases, for example, also lead to white blood cells being changed. It is also possible that you will have other symptoms.
