Sickle-cell disease is a single gene disorder where by the mutations in the beta-globin gene leads to formation of deformed haemoglobin molecules called haemoglobin S.
The signs and symptoms found in sickle-cell disease is the sickling of the red blood cells which leads to:
- premature break down of red cells,
- anaemia
- yellowing of eyes and skin (signs of jaundice)
- Painful episodes can occur when sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels.
