Thalassemia: The bloody disorder


Thalassemia is an inherited disorder of blood resulting in abnormal production of hemoglobin. The protein substance in blood. Hemoglobin carries oxygen, large numbers of which is destroyed leading to anemia. Anemia may be mild to severe and the symptoms include tiredness and pale and yellow skin.


Symptoms of thalassemia

  1. Deformities of bone, specially face

  2. Slow growth

  3. Yellow and pale skins

  4. Excessive fatigue

  5. Enlarged spleen

  6. Poor appetite

  7. Liver and kidney dysfunction

  8. Heart failure

Causes of Thalassemia: -

Thalassemia is a genetic disorder, inherited from the parents where mutation in one of the genes occur which is involved in hemoglobin production. If only one of the parents is the carrier of the gene then the disorder may result in thalassemia minor and if both the parents are the carrier of the disease then a severe form of thalassemia known as Thalassemia Major my result.

Diagnosis of Thalassemia-

Blood sample is taken by the lab to diagnose the abnormal forms of red blood cells in the blood. Hemoglobin electrophoresis separates the different molecules in the RBC’s, to identify the abnormal type.

Testing of embryos obtained through In vitro fertilization through PGD may detect the possibility of mutated genes in the embryo of carrier parents.

Types of thalassemia.

The classification of thalassemia is done as Alpha Thalassemia and Beta Thalassemia depending on the mutation on the type of genes. Hemoglobin is made up of alpha and beta globin and the mutation or missing number of these genes causes thalassemia. Depending on the severity it may be thalassemia minor or thalassemia major.

  1. Alpha Thalassemia: - It usually occurs when the body cannot produce alpha globin. A total of four genes, two from each parent is required for the production of alpha globin. This type can be further sub classified into two as:

a-Hemoglobin H- Occurs when three alpha globin genes have mutation or the three genes are missing in a person. Associated with the bone deformities of jaw, cheek and forehead this may also cause enlarged spleen, jaundice and malnourishment.

b-Hydrops fetalis- This extremely severe form occurs when all the four alpha globin genes are either missing or have mutations. It occurs before birth and the babies either die within a short span after being born or are stillborn.

  1. Beta Thalassemia: - It occurs when the body cannot make beta globin due to the missing or mutated genes, responsible for the production of beta globin. It is also further sub classified in two types

  1. Thalassemia major: The most severe form of beta thalassemia occurs when the beta globin genes are missing.

The symptoms generally show up before a child’s second birthday and the symptoms include:

1-Paleness of the skin

2- Poor appetite

3- Frequent infection

4- Severe life- threatening anemia requiring blood transfusions

5- Enlarged organs

6- Jaundice

b-Thalassemia intermedia: Less severe form of Beta thalassemia where two beta globin genes are missing or mutated. Usually don’t require blood transfusions.

Treatment of thalassemia:

There’s no way to prevent thalassemia as it is a genetic disorder, However, there are some ways to manage the disease to help prevent complications.

Blood transfusions

Medications such as folic acid, iron and vitamins

Bone marrow transplant

Surgery for spleen or gall bladder removal


Frequent blood transfusions are combined with Chelation therapy where an injection of a chemical is given that binds with iron and other heavy metals to remove extra iron from the body.

Thalassemia and Anemia: Reduced number of red blood cells are not capable of carrying proper oxygen to the tissues and organs leading to dizziness, fatigue, weakness and shortness of breadth. Severe conditions may be fatal and lead to organ failure.


Thalassemia and Fertility:

Thalassemia has some concerns related to pregnancy, resulting from poor development of reproductive organs to fertility issues. The iron levels should be monitored carefully and if pregnant prenatal testing through NIPT or Chorionic villi sampling for thalassemia is done at 11 and 16 weeks of gestation. Pregnant woman with thalassemia may develop following complications: -

Risk of frequent infections

Heart problems

Gestational diabetes

Increased blood transfusions

Hypothyroidism

Low bone density


The gene and genetics of Thalassemia: -


Thalassemia is a genetic disorder. Either one or both of the carrier parents have their children affected by Thalassemia minor or major. The only way to not to have children with thalassemia is genetic testing. The embryos are obtained through the procedure of IVF and cultured till blastocyst stage. One or more cells are taken out through biopsy and then preimplantation genetic diagnosis is done to rule out the possibility of genetic disease. The missed gene/genes or the mutated genes are diagnosed and only aneuploidy free embryos are transferred into the uterus. This technique ensures the birth of healthy baby. At Seeds of innocence we are committed not only to deliver babies but healthy babies by opting genetic testing in most of the IVF cases. Our genetic lab “Genestrings” is fully equipped with modern technologies to ensure the birth of healthy generations.
