When untreated, a person with SCA may suffer from painful periodic bouts, often causing damage to internal organs, strokes, or anemia. Typically, the disease results in premature death. Possible advantage of being heterozygous for sickle cell anemia disease (A) vs. normal blood cell response (B) when infected with malaria.
Exagamglogene autotemcel, sold under the brand name Casgevy, is a gene therapy used for the treatment of sickle cell disease [1] [3] and transfusion-dependent beta thalassemia. [1] It was developed by Vertex Pharmaceuticals and CRISPR Therapeutics .
The Sickle Cell Disease Association of America, Inc. (SCDAA) is a nonprofit organization with the sole purpose of supporting research, education and funding of individuals, families those who are impacted by sickle cell disease.
Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are single-gene disorders and, in most cases, they are inherited as autosomal co-dominant traits.
As the amount of fetal hemoglobin decreases and hemoglobin S increases, a mild hemolytic anemia appears in the early stage of development. Patients with this disease experience some of the symptoms of sickle cell anemia, including mild-moderate anemia, increased risk of infection, and painful sickling crises. [5]
Defects of red blood cell membrane production (as in hereditary spherocytosis and hereditary elliptocytosis). [2] Defects in hemoglobin production (as in thalassemia, sickle-cell disease and congenital dyserythropoietic anemia). [2] Defective red cell metabolism (as in glucose-6-phosphate dehydrogenase deficiency and pyruvate kinase deficiency ...
Healthy embryos are then selected and transferred into the mother's womb, while unhealthy embryos are discarded. In addition to Tay–Sachs disease, preimplantation genetic diagnosis has been used to prevent cystic fibrosis and sickle cell anemia among other genetic disorders. [34] Pre-marriage screening.
a decreased production of normal-sized red blood cells (e.g., anemia of chronic disease, aplastic anemia); an increased production of HbS as seen in sickle cell disease (not sickle cell trait); an increased destruction or loss of red blood cells (e.g., hemolysis, posthemorrhagic anemia, hypersplenism);
