    en.wikipedia.org/wiki/Sickle_cell_disease

    Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to a rigid, sickle -like shape under ...

    The types of anemia treated with drugs are iron-deficiency anemia, thalassemia, aplastic anemia, hemolytic anemia, sickle cell anemia, and pernicious anemia, the most important of them being deficiency and sickle cell anemia with together 60% of market share because of highest prevalence as well as higher treatment costs compared with other ...

    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.

    Such mutations are responsible for diseases such as Epidermolysis bullosa, sickle-cell disease, and SOD1-mediated ALS. [51] On the other hand, if a missense mutation occurs in an amino acid codon that results in the use of a different, but chemically similar, amino acid, then sometimes little or no change is rendered in the protein.

    In 2023, the first drug making use of CRISPR gene editing, Casgevy, was approved for use in the United Kingdom to cure sickle-cell disease and beta thalassemia. [ 13 ] [ 14 ] Casgevy was approved for use in the United States on December 8, 2023, by the Food and Drug Administration .

  7. Genetics - Wikipedia

    en.wikipedia.org/wiki/Genetics

    Sickle-cell versions of hemoglobin stick to themselves, stacking to form fibers that distort the shape of red blood cells carrying the protein. These sickle-shaped cells no longer flow smoothly through blood vessels, having a tendency to clog or degrade, causing the medical problems associated with this disease. [citation needed]

    1 in 10,000 people [2] Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting. [3][4][5] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. [6] It may also appear later in life and then ...
