Question

what causes sickle cell?

Explanation:

Sickle cell (sickle cell disease) is caused by a genetic mutation. Specifically, it's an inherited disorder resulting from a mutation in the gene that codes for hemoglobin (the protein in red blood cells that carries oxygen). This mutation leads to the production of abnormal hemoglobin (hemoglobin S), which causes red blood cells to become rigid and sickle - shaped under certain conditions. These abnormal cells can get stuck in blood vessels, leading to various complications.

Sickle cell (sickle cell disease) is caused by a genetic mutation in the gene that codes for hemoglobin, leading to abnormal hemoglobin (hemoglobin S) production and sickle - shaped red blood cells.
