Beta thalassemia major causes major problems and can result in early death. Complications may include delayed growth, bone problems causing facial changes, liver and gall bladder problems, enlarged spleen, enlarged kidneys, diabetes, hypothyroidism, and heart problems.

Beta thalassemia major (Cooley’s anemia) is the most severe kind of beta thalassemia. It involves having two missing or defective beta-globin genes. Beta thalassemia major is now known as “transfusion-dependent thalassemia” because people …

2023年5月1日 · Beta-thalassemia refers to an inherited mutation of the beta-globin gene, causing a reduced beta-globin chain of hemoglobin. The highest prevalence of beta-thalassemia mutations is in people of Mediterranean, Middle Eastern, and Asian descent.

Beta-thalassemia (β-thalassemia) is an inherited blood disorder, and a form of thalassemia resulting in variable outcomes ranging from clinically asymptomatic to severe anemia individuals. It is caused by reduced or absent synthesis of the beta chains of hemoglobin, the molecule that carries oxygen in the blood. [5] .

2023年9月15日 · Beta-thalassemia major demonstrates a complete absence of beta-globin chain (beta0/beta0), therefore the HbF is 92% to 95%, HbA2 is 5% to 8%, and HbA 0%. Elevated HbA2 is also caused by hyperthyroidism, vitamin B12 and …

2000年9月28日 · 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).

2022年6月3日 · Thalassemia major is the most serious form and usually requires regular treatment. There are two types of thalassemia — alpha thalassemia and beta thalassemia — named after defects in these chains.

There are two main forms of Beta-thalassemia, classified based on the severity of symptoms: Thalassemia major (also called Cooley's anemia) - the more severe form, causing severe anemia and enlarged liver and spleen (hepatosplenomegaly).

Beta thalassemia is a group of genetic blood disorders that share in common the defective production of hemoglobin, similar to sickle cell. Learn about symptoms, treatment, who is a carrier, and diagnosis for beta thalassemia.
