Genes passed from parents to children cause it. They affect hemoglobin, a blood protein. Sickle cell anemia, which is severe, happens if you inherit two copies of the sickle cell gene -- one from each parent. Sickle cell trait happens if you have one copy plus one normal gene. That mean...
Whereas some believe that screening or a priori knowledge of sickle cell trait (SCT) status may potentially save lives, others argue that screening may do more harm than good. In January 2012, the American Society of Haematology (ASH), which represents over 16 000 physicians and researchers, ...
The combination, in itself, of G6PD deficiency and sickle cell trait does not pose any particular problem. There is little or no interaction between G6PD deficiency and sickle cell trait. Because both traits are so frequent in some populations (peoples whose ancestors came from Sicily, Sardinia, ...
Hemoglobin helps red blood cells bind to and transport oxygen to cells and tissues of the body. Sickle cell is a result of a mutation in the beta-globin gene. This mutation results in red blood cells that are sickle-shaped, which causes them to clump together and become stuck in blood ve...

Sickle cell traitGenetic counselingIn August 2010, the National Collegiate Athletic Association (NCAA) mandated that all of its incoming Division I student-athletes be tested for sickle cell trait. Student-athletes have the additional options to provide proof of a previous sickle cell test result or...

Malaria is endemic in many areas of Africa and Asia. Malaria is such a fixture in certain parts of Africa that a protective mutation—sickle cell trait—has become common in local populations.9 Thesickle cell genemakes people less susceptible to malaria. However, it works best when people have...
It is a disease that was intended by God first never to happen. But only the trait. Because the trait fought malaria . . . since we know life was created in Africa first, this had [to be] the place to be able to develop so that it became the disease to prevent His population ...
