Thalassaemia is an inherited blood disorder where due to the instability of the wall of the red blood cell (RBC), the patient constantly suffers from anaemia (low levels of haemoglobin, the oxygen carrying part of the RBCs). It is estimated that one in 20 Malaysians are thalassaemia carriers, which is about 1.5 million Malaysians, affecting mainly the Chinese. If both parents of a child are thalassaemia carriers, there is a 25% chance the child have major thalassaemia, which is a serious condition. PGD now offers a chance for the couple to have a disease free child by testing the embryos created from IVF for the thalassaemia gene before being implanted into the womb. This also effectively stops the thalasaemia gene from being passed down to the subsequent generations.
