Background: Cardiac dysfunction due to chronic anemia and hemosiderosis are the major causes of death among patients with thalassemia intermedia. This study was performed to compare the cardiac function in thalassemia intermedia patients with normal subjects by means of echocardiography. Materials and Methods: This was a case-control study performed on 22 patients affected by thalassemia int...
A cohort of 106 patients included in the French National Registry for Thalassemia were genotyped for 5 genetic modifiers of severity: (i) beta-thalassemia mutations, (ii) the XmnI SNP, (iii) the -3.7 kb alpha-thal deletion, (iv) the tag-SNP rs 11886868 in BCL11A exon 2 and (v) the tag-SNP rs9399137 in the HBSB1L-cMYB inter-region. Multivariate analysis was performed to study the risk of Thalass...
Beta thalassemia dominant results from mutations in the β globin chain gene resulting in the production of elongated, highly unstable beta globin chains. Several such mutations have been described and in a heterozygous state they may confer a phenotype more severe than that of β thalassemia trait and lead to a clinical syndrome of thalassemia intermedia and its associated complications such as ...
The hereditary persistence of fetal hemoglobin (HPFH) and delta beta thalassemia are heterogeneous disorders characterised by increased levels of fetal hemoglobin and high level of this Hb continues in adulthood. The distinction between these two conditions is not always possible with routine hematologic analysis and molecular characterisation of the defect is required. We encountered such a ra...
background: thalassemia syndromes are the most prevalent single gene disorders in iran. this study aimed to evaluate the effect of different types of beta-globin gene mutations, co-inheritance of alpha-globin gene mutations and/or xmn1 snp on disease phenotype in a large cohort of iranian patients. subjects and methods: in total, 433 patients were clinically classified into β-thalassemia major ...
