These independent events occurred between 3000 and 6000. Anemia Sickle Cellpathology Anemia Sickle Celltherapy. Sickle-cell disease is inherited in the autosomal recessive pattern.

Sickle cell disease is a genetic disorder caused by mutations in the beta globin gene that leads to faulty hemoglobin protein called hemoglobin S. What we call its discovery in 1910 occurred not in Africa but in the United States. 1The Bill Melinda Gates Foundation Seattle WA 98119 USA.

DNA polymorphism of the beta S gene suggests that it. SCD originated in West Africa where it has the highest prevalence.

Herrick discovered that the mans red blood cells exhibited an abnormal shape. The sickle cell allele most likely origunated when a mutation occurred in a normal hemoglobin allele. Falx was a synonym but was later used to mean any of a number of tools that had a curved blade that was.
