Causes of Thalassemia

The prime cause of thalassemia is the inheritance of the affliction in recessive fashion. When both the parents carry the thalassemia trait, it leads to 25% of transmittance of the affliction in the offspring. However, there has been evidence of dominant inheritance of the disease.

When both the parents are thalassemia positive, genetic check-up and counseling is recommended to prevent or avert the affliction in the progeny.
