heterozygous beta thalassemia|Beta Thalassemia : Cebu Although the IVS-II-654(C>T)β + heterozygous mutation may cause ‘light’ β-thalassemia that does not require special treatment, homozygous and compound heterozygous mutations may lead to severe disease and the affected patient usually requires regular blood transfusions.

heterozygous beta thalassemia,
Beta-thalassemia minor, also called carrier or trait, is the heterozygous state that is usually asymptomatic with mild anemia. Homozygosity or compound heterozygosity for beta-thalassemia mutations cause a more severe spectrum of anemias called beta-thalassemia intermedia and beta-thalassemia major.
Beta thalassemia is an inherited blood disorder that limits your body’s ability to make beta-globin. Beta-globin is an important protein needed to make hemoglobin and red blood cells. Beta thalassemia can cause you to experience anemia symptoms. Types include beta thalassemia major, beta thalassemia intermedia and beta thalassemia minor.
Beta thalassemia trait (beta thalassemia minor) involves heterozygous inheritance of a beta-thalassemia mutation. Individuals usually have microcytosis with mild anemia; they are usually asymptomatic or have mild symptoms. [ 20 ]Individuals doubly heterozygous for α- and β-thalassemia have microcytosis but essentially normal circulating hemoglobin concentrations. Individuals homozygous for β-thalassemia who inherit a chromosome having a single α-globin gene deletion may have a milder phenotype, whereas deletion of both α-globin genes on one chromosome is typically .Beta Thalassemia Beta-thalassemia (β-thalassemia) has two clinically significant forms, β-thalassemia major and β-thalassemia intermedia, caused by absent or reduced synthesis of the hemoglobin subunit beta (beta globin chain).heterozygous beta thalassemia Beta Thalassemia Beta-thalassemia (β-thalassemia) has two clinically significant forms, β-thalassemia major and β-thalassemia intermedia, caused by absent or reduced synthesis of the hemoglobin subunit beta (beta globin chain).

Thalassemias are a heterogeneous grouping of genetic disorders that result from a decreased synthesis of alpha or beta chains of hemoglobin (Hb). Hemoglobin serves as the oxygen-carrying component of the red blood cells. It consists of two proteins, an alpha, and a .heterozygous beta thalassemia Thalassemias are a heterogeneous grouping of genetic disorders that result from a decreased synthesis of alpha or beta chains of hemoglobin (Hb).

Individuals with thalassemia major usually come to medical attention within the first two years of life .
