WebWhat causes alpha thalassemia? Alpha thalassemia occurs when some or all of the 4 genes that make hemoglobin (the alpha-globin genes) are missing or damaged. There are 4 types of alpha thalassemia: Alpha thalassemia silent carrier. One gene is missing or damaged, and the other 3 are normal. Blood tests are usually normal. WebMost b-thal patients in Japan are heteorozygote and thal minor as a phenotype. They are prone to be misdiagnosed as iron deficiency anemia. Thirty-four mutations of b-thal were thus far identified, and ten of which comprise 80% of beta-thal carriers. Among them 60% are unique to Japanese and 40% possibly from abroad.

Beta thalassemias (β thalassemias) are a group of inherited blood disorders. They are forms of thalassemia caused by reduced or absent synthesis of the beta chains of hemoglobin that result in variable outcomes ranging from severe anemia to clinically asymptomatic individuals.
