Beta Thalassemia Minor

Persons with beta thalassemia minor rarely have physical signs or symptoms caused by this disorder and usually do not require any treatment. Hemoglobin levels may be slightly decreased but with little clinical consequence.

In this type of beta thalassemia, the body is able to produce enough hemoglobin A (due to a decreased, but adequate beta globin chain production), so oxygen delivery is close to normal as is the red blood cell lifespan.

This form of beta thalassemia does not typically require treatment as there are very little symptoms present, if any. In addition, these individuals will have a normal life expectancy.

The genotypes associated with beta thalassemia minor are B0/B or B+/B.
