Abstract
The type of beta thalassemia mutation found in heterozygous individuals is believed to influence hematological symptoms. Our data demonstrated that patients with the mild mutation (beta IVSI-nt 6) have a higher mean corpuscular hemoglobin (MCH) than those with the severe forms (beta(0)039 or beta IVSI-nt 1), and the hemoglobin A(2) levels were lower in beta(0) mutations than in the beta IVSI-nt 6 mutation. However, in contrast to previous studies, we were not able to indicate MCH as a clear discriminator between the beta(0) and beta(+) mutations.20231932
