Thalassaemia test result showing 4.2 gene deletion usually means that the patient is α-resting thalassaemia, which is a thalassaemia gene carrier.
Normal people inherit 2 α-protein genes from each parent, and if there is an abnormal α-gene in thalassemia, it is thalassemia quiescent, and the patient may not have any clinical symptoms, and will not show the symptoms of thalassemia, such as dizziness and weakness, pallor, yellowish sclera, hepatosplenomegaly and other symptoms, and it does not affect normal growth and development, and the patient can have a normal work and life.
However, thalassemia gene carriers need to pay attention to the fact that if their spouses are also thalassemia gene carriers, there is a possibility that their offspring will have moderate or severe thalassemia, which will cause serious effects. Therefore, patients should undergo strict marriage examination before marriage and regular examination before and during pregnancy.
It is recommended that patients should consult a medical professional if they have any questions, and take a good marriage test as well as a pregnancy test.
