Sickle cell disease (sickle cell anemia) is a genetic, inherited disease affecting red blood cells, in which a child can be ill if both parents are transmitters, ie asymptomatic carriers of the gene for sickle cell disease. It is a hereditary autosomal recessive disease, that is, it affects girls as well as boys, and only manifests itself when one carries two genes of the disease.
