Hemoglobin 2019 Jan 9:1-3. Epub 2019 Jan 9.

b Department of Paediatric Oncology, Haematology and Immunology , Heidelberg University , Heidelberg , Germany.

Over the last 43 years, surveys of over 200,000 subjects in Jamaica have identified β-thalassemia (β-thal) mutations. In most, these genes were detected at birth in patients with sickle cell-β-thal and so the prevalence and distribution would not be influenced by subsequent clinical course. There were two newborn populations, 100,000 deliveries in the corporate area between 1973-1981 and 84,940 in south and western Jamaica between 2008-2016. Read More

Novel nonsense mutation in the α1-globin gene [HBA1:C.49A>T] is responsible for non-deletion α-thalassemia.

Clin Biochem 2019 Jan 26;63:139-142. Epub 2018 Oct 26.

Servicio de Hematología y Hemoterapia, Hospital Clínico San Carlos, Madrid, Spain.

Background: In the α-thalassemia one of the less frequent mechanisms is the nonsense mutations, which generate the substitution of a triplet that encodes an amino acid for a stop codon and, therefore, protein synthesis stops prematurely. At present, 9 mutations of this type have been documented, 6 that affect the HBA2 gene and 3 that affect the HBA1 gene.

Objectives: We present a new mutation in CD16 of the HBA1 gene, where the change AAG>TAG generates a stop codon. Read More

Global analysis of erythroid cells redox status reveals the involvement of Prdx1 and Prdx2 in the severity of beta thalassemia.

PLoS One 2018 6;13(12):e0208316. Epub 2018 Dec 6.

Universidade Federal de São Carlos (UFSCar), Departamento de Genética e Evolução, São Carlos, Brazil.

β-thalassemia is a worldwide distributed monogenic red cell disorder, characterized by an absent or reduced beta globin chain synthesis. The unbalance of alpha-gamma chain and the presence of pathological free iron promote severe oxidative damage, playing crucial a role in erythrocyte hemolysis, exacerbating ineffective erythropoiesis and decreasing the lifespan of red blood cells (RBC). Catalase, glutathione peroxidase and peroxiredoxins act together to protect RBCs from hydrogen peroxide insult. Read More

Common fetal hemoglobin variants in Lebanese patients bearing the codon 29 beta gene mutation associated with different thalassemia phenotypes.

Ann Hematol 2018 Nov 30. Epub 2018 Nov 30.

Department of Internal Medicine, American University of Beirut Medical Center, PO Box 11-0236, Beirut, 11072020, Lebanon.

Beta-thalassemia can present with a wide spectrum of phenotypes determined by the coinheritance of α-thalassemia, hereditary persistence of fetal hemoglobin, and polymorphic variants in the BCL11A, HMIP, and HBB clusters. The codon 29 (cd29) mutation in the beta gene has been associated with a broad diversity of thalassemia phenotypes, possibly through genetic modifiers determining the genotype-phenotype relationship. In this study, we evaluated the effect of 10 single nucleotide polymorphisms (SNPs) on β-thalassemia severity in a group of 21 Lebanese patients bearing the cd29 mutation. Read More

University College London, London, United Kingdom.

Transfusion combined with chelation therapy for severe β thalassemia syndromes (transfusion-dependent thalassemia [TDT]) has been successful in extending life expectancy, decreasing comorbidities and improving quality of life. However, this puts lifelong demands not only on the patients but also on the health care systems that are tasked with delivering long-term treatment and comprehensive support. Prevention programs and curative approaches are therefore an important part of overall strategy. Read More
