Sickle cell disease: MedlinePlus Genetics

WebSickle cell disease (SCD) is a genetic disorder caused by a mutation in both copies of a person’s HBB gene. This gene encodes a component of hemoglobin, the oxygen-carrying protein in red blood cells. The mutation causes hemoglobin molecules to stick together, creating sickle-shaped red blood cells. This can lead to blood cell rupture, anemia ... WebHemoglobin S arises as a result of a point mutation (A–T) in the sixth codon of the β-globin gene on chromosome 11, which causes a single amino acid substitution (glutamic acid to valine at position 6 of the β-globin chain).
