A Thalassemia SEA heterozygous generally refers to thalassemia SEA deletion heterozygous, which is mild and usually does not worsen with active treatment.
Thalassemia is a hereditary, hemolytic anemia disease that can be divided into two categories: α-thalassemia and β-thalassemia. It is caused by α-thalassemia gene or β-thalassemia gene deletion and mutation respectively.
Thalassemia SEA deletion heterozygous refers to the detection of SEA deletion, which indicates that two of its four alpha-pearl protein genes are missing and the other two are normal, and is classified as mild alpha-thalassemia.
Patients may have symptoms of mild anemia, such as dizziness and nausea. There may also be no obvious symptoms of anemia, but microcytic hypochromicity can be found in routine blood tests. After active treatment, the symptoms of most patients can be relieved or reduced, and usually will not continue to deteriorate.
It is recommended that patients with thalassemia go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying their condition.
