An inherited disorder of red blood cells with only mild anemia. (See Sickle Cell Anemia.)
The condition in which a person has both normal and sickle hemoglobin in the red cells as a result of inheriting a normal hemoglobin gene and a gene for sickle hemoglobin. Sickle cell trait is not a disease and does not change to sickle cell disease. Persons with sickle cell trait may pass the sickle gene to their children.
Sickle cell trait means that the child is a carrier of a sickle cell disorder. Testing for sickle cell disorders also detects babies with sickle cell trait. Although an infant with sickle cell trait does not have the problems of sickle cell disorders, if his or her parents are both carriers they could have another child who does have a sickle cell disorder.
The inheritance of one gene for the usual hemoglobin (A) and one gene for sickle hemoglobin (S). A person who has sickle cell trait (AS) is a carrier of the sickle gene, does not have the disease, does not have painful episodes, and is generally not affected by the sickle hemoglobin.
a normal hemoglobin gene is inherited from one parent and a single hemoglobin gene from the other.
A person who has one gene for sickle cell anemia is said to have sickle cell trait. Sickle cell trait cannot change to become sickle cell anemia. A person will develop sickle cell anemia only if both parents pass on the trait (gene) to him or her.
having one copy of the gene which causes sickle cell anemia (HbS), and one copy of the normal hemoglobin gene.
Symptoms shown by those possessing a heterozygous genotype for sickle cell anemia.
Sickle cell trait describes the way a person can inherit some of the genes of sickle cell disease, but not develop symptoms. Sickle cell disease is a blood disorder in which the body produces an abnormal type of the oxygen-carrying substance hemoglobin in the red blood cells.
