DNA Direct - How Testing for Alpha-Thalassemia Works

Blood tests are usually sufficient to to confirm alpha-thalassemia carrier status. Genetic testing is needed to confirm the type, and therefore severity, of alpha-thalassemia. In practice, genetic testing is usually only performed in people at risk for alpha -thalassemia. The vast majority (about 90%) of alpha-globin mutations are deletions.

Testing for Thalassemia Trait

A trait carrier of thalassemia will always be a trait carrier. It is a genetic trait passed down from parents to children. Being a trait carrier is not contagious. Over two million people in the United States carry the genetic trait for thalassemia. There are two types of thalassemia trait: Alpha thalassemia trait and Beta thalassemia trait.

Genetic testing can help with this diagnosis, since severity of β-thalassemia can partially be predicted from the nature of the causative mutations in HBB, the gene coding for β-globin. In addition, genetic testing can also identify mutations associated with rare cases of dominantly inherited β-thalassemia.

What Blood Tests Are Done To Detect Thalassemia?

 · Reason for this is that beta thalassemia disturbs the balance of chain formed by alpha and beta hemoglobin components. Because of this, such patients have Hemoglobin F in relatively higher percentage, while hemoglobin HbA2 in elevated fraction than of normal ones. Hemoglobin H is present among patients dealing with alpha thalassemia problem.

Beta-Globin-Related Hemoglobinopathies (HBB) - Sema4

Pathogenic variants in the beta-globin gene (HBB) cause a variety of autosomal recessive diseases of aberrant hemoglobin, the protein that carries oxygen in the blood. The most frequent hemoglobinopathies are beta-thalassemia, sickle cell disease and HbC disease. In individuals with beta-thalassemia, hemoglobin is not properly synthesized and results in small red blood cells that are […]
