Sickle cell anemia is caused by an abnormalHBB gene. The abnormal hemoglobin produced by this gene mutation (hemoglobin S) can cause the red blood cells to form into an abnormal sickle shape.3 A normal RBC lives for about 120 days before the cell dies.

This impairs its function of carrying oxygen in the blood and hence can cause symptoms of anaemia such as dizziness, rapid heart rate and fatigue. Quite rarely, a condition is caused by a simple point mutation of just one DNA base. This …
