WebNov 25, 2024 · Sickle cell disease (SCD) is a group of inherited red blood cell disorders. If you have SCD, there is a problem with your hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells.

WebJan 1, 2015 · 1. Introduction. Sickle cell disease (SCD) or sickle cell anemia (SCA) is an inherited disorder of hemoglobin (Hb) caused by substitution of a single nucleotide from thymine to adenine (GAG → GTG) in the β-chain of hemoglobin resulting in amino acid valine instead of glutamic acid (Rees et al., 2010).This point mutation is responsible for … WebMar 13, 2024 · Summary. Sickle cell anaemia is a disease of red blood cells. It is caused by an autosomal recessive single gene defect in the beta chain of haemoglobin, which results in production of sickle cell haemoglobin (HbS). Sickle cells can obstruct blood flow and break down prematurely, and are associated with varying degrees of anaemia.
