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.
Base-pair substitution that causes sickle cell anemia. The gene defect is a single nucleotide mutation of the β-globin gene, which results in glutamate being substituted by valine at position 6 of the β-globin chain. [62] Hemoglobin S with this mutation is referred to as HbS, as opposed to the normal adult HbA.
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.

Testing HbA2 levels can be challenging because different disorders can cause it to have higher or lower values. Testing for the beta-thalassemia trait is usually identified when the value of HbA2 is higher than 3.5%. [3] HbA2 is also important for diagnosing sickle cell disease, which is one of the most prevalent genetic conditions.
Photomicrograph of normal-shaped and sickle-shape red blood cells from a patient with sickle cell disease. Sickle cell anemia is a genetic disease that causes deformed red blood cells with a rigid, crescent shape instead of the normal flexible, round shape. [29] It is caused by a change in one nucleotide, a point mutation [30] in the HBB gene.
The trait is normal-functioning and has no known negative effects. [2] The mutation was first discovered in 1971, during the boom of research in to hemoglobin. [3] The push was backed by the desire to research the causes and possibly fight sickle cell anemia and other types of Anemia. Because the strict laws of clinical testing had not existed ...
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]
