A genetic problem causes sickle cell anemia. People with the disease are born with two sickle cell genes, one from each parent. If you only have one sickle cell gene, it’s called sickle cell trait. About 1 in 12 African Americans has sickle cell trait.

The most common symptoms are pain and problems from anemia. Anemia can make you feel tired or weak. In addition, you might have shortness of breath, dizziness, headaches, or coldness in the hands and feet.

A blood test can show if you have the trait or anemia. Most states test newborn babies as part of their newborn screening programs.

Sickle cell anemia has no widely available cure. Treatments can help relieve symptoms and lessen complications. Researchers are investigating new treatments such as blood and marrow stem cell transplants, gene therapy, and new medicines.
