Molecular Basis of β-Thalassemia Intermedia in Erbil Province of Iraqi Kurdistan.

abstract：:β-Thalassemia (β-thal) is the most frequently observed hereditary blood disorder that results from genetic defects causing deficient synthesis of hemoglobin (Hb) polypeptide chains. Detecting thalassemia mutations are necessary for prenatal diagnosis (PND) programs leading a better quality of life for the patients, as...
