Sickle cell disease is caused by a genetic mutation in the hemoglobin within red blood cells. This abnormal hemoglobin sticks together, changing the shape of a person's red blood cells. These misshapen cells can disrupt blood flow, leading to pain, anemia, infection, and other complications. Pe...
Hemoglobin SS disease; Sickle-cell anemia Definition Sickle-cell disease is a hereditary condition in which red blood cells form abnormal crescent shapes, instead of their usual disk shapes. These abnormal cells tend to clump together more frequently than do normal red blood cells, and because of...

Sickle Cell Anemia Odds When Both Biological Parents Have Sickle Cell Trait Now, let’s talk odds. If both biological parents have sickle cell trait, then: Each child born to that couple has a 25% chance of inheriting two normal hemoglobin A genes. This outcome means the child doesnothave...

Because these cells are destroyed faster than they are made, people with sickle disease often have a shortage of red blood cells — a condition known as anemia, the most common symptom of the sickle cell. People with sickle cell also may experience swelling in the hands and feet, and ...
People with sickle cell disease are also prone to infections, anemia and enlarged spleens, said Dr. Radhika Peddinti, a pediatric hematologist at La Rabida Children's Hospital in Chicago. However, the prognosis for people with sickle cell disease has improved dramatically. "It used to be that...
A daily hydroxyurea pill may finally bring some relief for young children living with the painful and deadly blood disease sickle cell anemia (SCA) in resource-challenged sub-Saharan Africa, where the disease is prevalent and health care availability is
