How Is Thalassaemia Inherited?


    If only one parent has thalassaemia minor, the following can occur:

  • 50% chance of having a child with thalassaemia minor

  • 50% chance of having a normal child

  • None of the couple’s children will get thalassaemia major.


    If both parents have thalassaemia minor, the following can occur:

  • 25% chance of having a child with thalassaemia major

  • 50% chance of having a child with thalassaemia minor

  • None of the couple’s children will get thalassaemia major.


The chances are the same with each pregnancy, no matter how many children the couple may have.



Who Should Go For Thalassaemia Screening?

    Since thalassaemia can be passed on from one generation to another, you and your partner should go for a thalassaemia screening if you are:

  • Planning to get married

  • Starting a family.

Thalassaemia screening involves a simple blood test and is available at all polyclinics.
