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 ...

A normal RBC lives … WebPeople with all types of SCD inherit the gene for hemoglobin S from 1 parent and a gene for another type of hemoglobin from 1 parent. Hemoglobin S (also called sickle hemoglobin) is the most common type of abnormal hemoglobin. It has a mutation that causes it to form rigid strands that make red blood cells stiff and sickle-shaped. 1 Hemoglobin variants are different types of hemoglobin molecules, by different combinations of its subunits and/or mutations thereof. Hemoglobin variants are a part of the normal embryonic and fetal development. They may also be pathologic mutant forms of hemoglobin in a population, caused by variations in genetics.
