Can Thalassemias Be Prevented?

Thalassemias can't be prevented because they're inherited (passed on from parents to children). However, these bleeding disorders can be found before birth through prenatal tests.

Family genetic studies may help find out whether people have missing or altered hemoglobin genes that cause thalassemias. (For more information, see "How Are Thalassemias Diagnosed?")

If you know of family members who have thalassemias and you're thinking of having children, consider talking with your doctor and/or a genetic counselor. They can help determine your risk for passing on the disorder to your child.

Thalassemia Minor: Understanding the Silent Carrier

Introduction: Thalassemia is a genetic blood disorder characterized by abnormal hemoglobin production, leading to anemia. Thalassemia minor, also known as thalassemia trait or carrier state, is the mildest form of thalassemia. Individuals with thalassemia minor typically have one normal hemoglobin gene and one mutated hemoglobin gene. Although it is considered a mild condition, understanding thalassemia minor is crucial due to its implications for genetic counseling and potential complications during pregnancy. Genetic Basis and Inheritance: Thalassemia minor is inherited in an autosomal recessive manner, meaning that both parents must carry the gene mutation for their child to have thalassemia minor. The mutated genes affect the production of either the alpha or beta globin chains that make up hemoglobin, the protein responsible for carrying oxygen in the blood. The severity of thalassemia is influenced by the specific gene mutation and the extent to which the normal gene is affected....

Diagnosis

Thalassemia can be diagnosed in different ways. Some types can be found on routine blood tests that show that the red blood cells are small or the patient is anemic. Testing of parents can be done before pregnancy to determine whether there is a risk of having a child with a severe form of thalassemia. The illness can be seen in sophisticated genetic testing, and can be found prenatally through amniocentesis or chorionic villus sampling (CVS).

Innovations and Research

As one of five thalassemia centers in the United States designated by the National Institutes of Health, the Children's Hospital Boston thalassemia program provides patients with access to experts in the field and the most cutting-edge clinical trials available in the world. One promising recent study, now awaiting approval by the FDA, tested the effectiveness of a new oral iron chelator, deferisirox. Researchers from Children's Hospital Boston have been at the forefront of thalassemia research and treatment for decades. Important advances in the field that were made here include: • Recognition of the important role of hypertransfusion by Dr. David Nathan, Senior Associate in Hematology, in the 1960s. • Demonstration of effective iron chelation by subcutaneous pump deferoxamine (Desferal ®) by Dr. Richard Proper and David Nathan in the 1970s. • Elucidation of the molecular biology of thalassemia syndromes by Drs. Nathan, YW Kan, Stuart Orkin and others.
