Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous).
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. The most common type is known as sickle cell anemia. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells.
Sickle cell-beta thalassemia is an inherited blood disorder. The disease may range in severity from being relatively benign and like sickle cell trait to being similar to sickle cell disease.
For gene therapy to even be an option, people in developing nations must stay alive long enough to get it. There, sickle cell disease is more likely to disable or kill than in wealthy regions.
Sickle Cell Anemia, a Molecular Disease" is a 1949 scientific paper by Linus Pauling, Harvey A. Itano, Seymour J. Singer and Ibert C. Wells that established sickle-cell anemia as a genetic disease in which affected individuals have a different form of the metalloprotein hemoglobin in their blood.
In a hilly part of eastern Uganda that’s a sickle cell hot spot, the main referral hospital looks after hundreds of patients arriving from nearby villages to collect medication.
Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition. [1]
Sickle cell retinopathy can be defined as retinal changes due to blood vessel damage in the eye of a person with a background of sickle cell disease. It can likely progress to loss of vision in late stages due to vitreous hemorrhage or retinal detachment . [1]
Sickle cell nephropathy is a type of nephropathy associated with sickle cell disease which causes kidney complications as a result of sickling of red blood cells in the small blood vessels.
In 1954 he discovered, confirming his preconception, that people with sickle-cell trait are resistant to the deadly falciparum malaria . In the 1970s, Allison had worked out the enzyme, inosine monophosphate dehydrogenase, as a key molecule of the immune response in autoimmune diseases and in organ transplantation.
