WebJan 18, 2024 · Introduction. Sickle-cell disease (SCD) is a group of blood disorders caused by mutations in HBB that promote haemoglobin (Hb) polymerization and sickling of red blood cells. The most common and most clinically severe form of SCD is sickle-cell anaemia (SCA, MIM: 603903), caused by homozygosity of the sickle-cell gene variant [HBB; … WebSickle-cell disease results from a mutation in a protein called hemoglobin, that you'd find in red blood cells. This mutation turns hemoglobin into a much less functional form, which we'll call "HbS". It's much less efficient at moving oxygen around the human body. Another effect of sickle-cell disease is it makes the diseased person less ...

WebSickle hemoglobin (HbS) is caused by a mutation in the β globin gene which affects the stability and solubility of the β chain. When HbS is deoxygenated (e.g. during inflammation, infection, dehydration or hypoxia) it polymerizes and distorts the red cell, eventually resulting in the characteristic sickle shape.

WebThe first known protein-misfolding disease, indeed the first inherited human disease to have a known molecular mechanism, was sickle cell anemia.
