How is thalassemia defined?
Thalassemia (thal-uh-SEE-me-uh) is an inherited blood disorder that causes your body to have less hemoglobin than normal. Hemoglobin enables red blood cells to carry oxygen. Thalassemia can cause anemia, leaving you fatigued.
What type of anemia is thalassemia?
There are two main types of thalassemia: alpha and beta. Different genes are affected for each type. Thalassemia can cause mild or severe anemia. Anemia occurs when your body does not have enough red blood cells or hemoglobin.
What are the three types of thalassemia?
When you have beta thalassemia, your body doesn’t make enough protein in red blood cells called hemoglobin. That makes it hard for oxygen to get to all of your body’s cells. There are three main types of the disease: beta thalassemia major, intermedia, and minor.
What type of mutation is thalassemia?
Thalassemia is an inherited autosomal recessive disease resulting from mutations in the α- and β-globin gene clusters on chromosome 16 and chromosome 11, respectively. It is characterized by the absence or reduced synthesis of globin chains of hemoglobin and includes two main types, α- and β- thalassemia (1, 2).
What are the two major types of thalassemia?
There are two main types of thalassemia:
- Alpha thalassemia occurs when a gene or genes related to the alpha globin protein are missing or changed (mutated).
- Beta thalassemia occurs when similar gene defects affect production of the beta globin protein.
What gene is thalassemia?
What is thalassemia test called?
Hemoglobin electrophoresis is used to diagnose beta thalassemia.
What is alpha and beta thalassemia?
The thalassemias are a group of inherited hematologic disorders caused by defects in the synthesis of one or more of the hemoglobin chains. Alpha thalassemia is caused by reduced or absent synthesis of alpha globin chains, and beta thalassemia is caused by reduced or absent synthesis of beta globin chains.
Which gene is responsible for thalassemia?
Mutations in the HBB gene cause beta thalassemia. The HBB gene provides instructions for making a protein called beta-globin. Beta-globin is a component (subunit) of hemoglobin . Hemoglobin consists of four protein subunits, typically two subunits of beta-globin and two subunits of another protein called alpha-globin.
Is thalassemia a beta anemia?
Beta thalassemia major (also called Cooley’s anemia). People with beta thalassemia major have life-threatening anemia. They need regular blood transfusions and other medical care.
