The mutation which causes sickle cell disease results in an abnormal hemoglobin known as hemoglobin S (HbS), which replaces HbA in adults. [20] The human genome contains a pair of genes for β-globin; in people with sickle cell disease, both genes are affected and the erythropoietic cells in the bone marrow will only create HbS.
Sickle cell disease is a blood disorder wherein there is a single amino acid substitution in the hemoglobin protein of the red blood cells, which causes these cells to assume a sickle shape, especially when under low oxygen tension.
The hemoglobin structural variants can be broadly classified as follows: [19] Sickle cell disorders, which are the most prevalent form of hemoglobinopathy. Sickle hemoglobin (HbS) is prone to polymerize when deoxygenated, precipitating within the red blood cell. This damages the RBC membrane resulting in its premature destruction and consequent ...
Hemoglobin S (α 2 β S 2) – A variant form of hemoglobin found in people with sickle cell disease. There is a variation in the β-chain gene, causing a change in the properties of hemoglobin, which results in sickling of red blood cells.
[15] [16] [17] Hemoglobin C gene is found in 2-3% of African-Americans [4] while 8% of African-Americans have hemoglobin S (Sickle) gene. Thus Hemoglobin SC disease is significantly more common than Hemoglobin CC disease. The trait also affects people whose ancestors came from Italy, Greece, Latin America, and the Caribbean region. [4]
Sickle cell-Hb Lepore Boston syndrome is a type of sickle cell disease (HbS) that differs from homozygous sickle cell disease where both parents carry sickle hemoglobin. In this variant one parent has the sickle cell hemoglobin the second parent has Hb Lepore Boston, the only one of the three variants described in association with HbS. [7]
For people living with the disease, a sickle cell crisis can happen at any time. When it does, their rigid, sickle-shaped red blood cells become stuck in their blood vessels, blocking flow and ...
Hemoglobin A (HbA), also known as adult hemoglobin, hemoglobin A1 or α 2 β 2, is the most common human hemoglobin tetramer, accounting for over 97% of the total red blood cell hemoglobin. [1] Hemoglobin is an oxygen-binding protein, found in erythrocytes , which transports oxygen from the lungs to the tissues. [ 2 ]
