What is Sickle Cell Disease?
Sickle Cell Disease (SCD) is a group of inherited red blood cell disorders that is present from birth. Normal red blood cells are round and move easily through blood vessels. For someone who has SCD, the red blood cells become hard and sticky, and have a C-shape, like a farmer’s sickle. These “sickled” cells become stuck in blood vessels and block blood flow. In addition to the changes in red blood cell shape, these sickled cells die early, which results in a constant shortage of red blood cells. This can cause pain, damage to body organs and anemia.
SCD is inherited, which means it can run in families. It occurs when a person gets two sickle cell genes, one from each parent. A person cannot catch this disease from someone else.
What is Sickle Cell Trait?
Sickle cell trait is not a disease, but it can be passed on to your children. When a person has sickle cell trait (SCT), they are a carrier of the sickle cell gene. This means a person with SCT could pass the trait on to their children. People who inherit one sickle cell gene and one normal gene have sickle cell trait. However, someone who has SCT will not get SCD; sickle cell trait does not change into sickle cell disease.
