Causes of sickle cell anaemia. Sickle cell anaemia is caused by a genetic mutation that affects the normal development of haemoglobin. A genetic mutation is a permanent change in the normal pattern of genetic information inside all living cells.This results in one or more of the body's processes not working properly.ickle cell anaemia is caused by a genetic mutation that affects the normal development of haemoglobin.

Abnormal hemoglobin, called hemoglobin S, causes sickle cell disease (SCD). The problem in hemoglobin S is caused by a small defect in the gene that directs the production of the beta globin part of hemoglobin. A 25 percent chance of inheriting two normal genes: In this case the child does not have sickle cell trait or disease. ( 2 Case 1). 3  A 50 percent chance of inheriting one hemoglobin A gene and one hemoglobin S gene: This child has sickle cell trait.
