Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
Autosomal dominant A 50/50 chance of inheritance. 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.

The sickle cell trait provides a survival advantage against malaria fatality over people with normal hemoglobin in regions where malaria is endemic. The trait is known to cause significantly fewer deaths due to malaria, especially when Plasmodium falciparum is the causative organism.
Sickle cell disease is a group of inherited blood disorders, caused by a genetic abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [57] Under certain circumstances, this leads to the red blood cells adopting an abnormal sickle -like shape; with this shape, they are unable to deform as they pass through capillaries ...
In cases of a sickle cell bone marrow transplant, the best results come from a sibling. A sibling HLA match gives the procedure a 95% success rate, as opposed to a rate of around 78% with an ...

A few indications and symptoms include anemia , sporadic episodes of excruciating pain, hand and foot edema , recurrent infections , delayed puberty or growth, and visual issues . [ 19 ]
The characteristic sickle-shaped appearance of red blood cells can be observed. Sickle cell disease , in which a mutation in the globin gene causes the formation of sickle hemoglobin . [ 2 ] This disease is marked by the manifestation of chronic compensated hemolytic anemia , with laboratory findings not limited to unconjugated ...
According to Kukushkin, the memories stored in non-brain cells in other parts of the body are memories strictly related to the roles that those specific cells play in human health. Thus, he detailed:
