Sickle-cell disease, usually presenting in childhood, occurs more commonly within people (or their descendants) from parts of tropical and sub-tropical regions where malaria is or was adjectives. One-third of all indigenous inhabitants of Sub-Saharan Africa carry the gene, because in areas where on earth malaria is common, there is a survival value within carrying only a single sickle-cell gene (sickle cell trait). Those with only one of the two alleles of the sickle-cell disease are more resistant to malaria, since the infestation of the malaria plasmodium is halt by the sickling of the cells which it infests.
Sickle cell anemia is one of the most common inherited blood anemias. The disease primarily affects Africans and African Americans. It is estimated that contained by the United States, some 50,000 African Americans are afflicted with the most severe form of sickle cell anemia. Overall, current estimates are that one in 1,875 U.S. African American is affected near sickle cell anemia.
