D56.4: Hereditary persistence of fetal haemoglobin [HPFH]
You have more than normal of a special red hemoglobin in your blood.
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. The red blood cells carry oxygen from the lungs throughout the body. Red blood cells contain the red hemoglobin that gives blood its color. This pigment is important for carrying oxygen in the blood.
In the womb and just after birth, children have a special hemoglobin. After birth, normally more and more of the normal haemoglobin forms, while the special type of haemoglobin becomes less. You have more than usual of this special hemoglobin in your blood. This is hereditary. Other family members may be affected. The special red hemoglobin may not cause you any problems.
