The type of mutation that causes sickle cell anemia is called a point mutation.
A point mutation in both copies of the HBB gene results in the hereditary illness sickle cell disease (SCD).
An element of hemoglobin, the protein in red blood cells that carries oxygen, is encoded by this gene. Because of the mutation, hemoglobin molecules clump together to form red blood cells with a sickle shape.
About 100,000 people in the US have the rare disease sickle cell anemia. It primarily affects persons who have ancestors in regions of the world where malaria is common and who also have a gene that offers some protection against anemia. Additionally, this gene causes sickle cell anemia.
