How is the hbb gene changed with sickle cell
Web11 feb. 2024 · Sickle cell disease results from a change in a key protein in hemoglobin, which helps transport oxygen in red blood cells. Hemoglobin normally allows “red blood cells to be very floppy... WebSickle cell disease (SCD) is an autosomal recessive genetic condition that describes a group of haemoglobin disorders caused by genetic variants in the HBB gene, resulting in the production of sickle haemoglobin (HbS) rather than normal haemoglobin A (HbA).
