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.

The sickle cell trait provides a carrier with a survival advantage against malaria fatality over people with normal hemoglobin in regions where malaria is endemic. [65] [66] Infection with the malaria parasite affects asymptomatic carriers of the abnormal hemoglobin gene differently from patients with full SCD. Carriers (heterozygous for the ...
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 anemia.
Renal medullary carcinoma is a rare type of cancer that affects the kidney.It tends to be aggressive, difficult to treat, and is often metastatic at the time of diagnosis. . Most individuals with this type of cancer have sickle cell trait or rarely sickle cell disease, suggesting that the sickle cell trait may be a risk factor for this type of ca
It is possible for a person to have both the gene for hemoglobin S (the form associated with sickle cell anemia) and the gene for hemoglobin C; this state is called hemoglobin SC disease, and is generally more severe than hemoglobin C disease, but milder than sickle cell anemia. [2]
In persons with sickle cell disease, high levels of fetal hemoglobin as found in a newborn or as found abnormally in persons with hereditary persistence of fetal hemoglobin, the HbF causes the sickle cell disease to be less severe. In essence the HbF inhibits polymerization of HbS. A similar mechanism occurs with persons who have sickle cell trait.
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]
