HBA1-related alpha thalassemia spectrum

HBA1-related alpha thalassemia spectrum, also known as alpha-thalassemia trait, is a condition caused by changes in the HBA1 gene. These genetic changes affect the production of hemoglobin, the protein in red blood cells that carries oxygen, leading to mild microcytic anemia. In microcytic anemia, red blood cells are smaller than normal, which may result in lower hemoglobin levels. This condition is generally mild and many people may not notice significant symptoms in daily life. Because the alterations occur in both copies of the HBA1 gene (biallelic variation), the impact on hemoglobin production is limited. While some individuals might experience mild fatigue or other subtle signs of anemia, the condition itself tends to be less severe compared to other forms of thalassemia. This understanding helps healthcare providers monitor and manage the health of people with this condition effectively.

The primary symptom seen in HBA1-related alpha thalassemia spectrum is mild microcytic anemia. This means that the red blood cells are smaller and may be fewer in number, which can sometimes result in mild fatigue or feelings of weakness. However, many people with this condition experience few noticeable symptoms and may remain largely asymptomatic.

This condition is caused by biallelic variation in the HBA1 gene. In people with HBA1-related alpha thalassemia spectrum, both copies of the gene have changes that affect the production of hemoglobin. As a result, the decrease in hemoglobin is generally mild, which helps explain why the condition typically leads to a less severe form of anemia.
