particularly common in populations from sub-Saharan Africa, the Caribbean, India,
the Middle East and the Mediterranean basin.
The characteristics of the different levels of the phenotype of sickle cell
disease are:

(blood circulation is Unusual).
- At the cellular level: the low number of red blood
cells, Change its shape (crescent, or sickle), this latter leads to the blockage
of blood vessels and thus non saturate tissue of blood
