Thalassemia is a type of anemia that is characterized by a deficiency in the synthesis of bead protein peptide chains, and carriers of bead protein disorders are those who carry the gene that causes bead protein disorders but do not have any obvious clinical symptoms. PDNA is a hereditary hemolytic anemia caused by a mutation or deletion of the hemoglobin peptide chain gene, resulting in a reduction or complete absence of peptide chain synthesis, and is a common single-gene disorder. Carriers of peptidergic anemia are those who do not have obvious clinical symptoms, but can be detected by genetic testing for the gene deletion. Usually, no special treatment is needed if there are no uncomfortable symptoms. However, it is important to note that carriers may give birth to a child with severe PD anemia, and prenatal genetic diagnosis is recommended. If carriers of PDAP experience discomfort, it is recommended that they go to a regular hospital and undergo relevant tests to determine the cause of the disease.
