Alpha thalassemia deletions found in suspected cases of beta thalassemia major in Pakistani population
BACKGROUND & OBJECTIVE Alpha (α) thalassemia is a hereditary disorder and is caused by deletions or mutations in globin genes. It is present in two clinically significant forms: hemoglobin Bart hydrops fetalis (Hb Bart) syndrome and hemoglobin H (HbH) disease. It is highly prevalent in South-East Asia or Mediterranean countries. The most common deletion reported in alpha thalassemia in Pakistan...
متن کاملSkeletal and extraskeletal manifestations of mixed alpha and beta thalassemia
A 33-year-old male with known thalassemia intermedia presented with acute mid-back pain. Radiography and MRI were useful to evaluate the extent of iron deposition and assess for complications (such as cirrhosis) of the disease.
متن کاملMild thalassemia: the result of interactions of alpha and beta thalassemia genes.
Homozygous thalassemia is due to inherited unbalanced synthesis of the alpha- or beta-chains of hemoglobin. Clinical severity may be in part related to the extent of alpha:beta imbalance. Two families are presented that illustrate this concept. Thalassemia in these individuals was evaluated by clinical and genetic criteria. The relative rates of alpha- and beta-chain synthesis in their reticulo...
متن کاملControlling alpha-globin: a review of alpha-globin expression and its impact on beta-thalassemia.
Synthesis of alpha-globin and alpha-globin subunits of hemoglobin occurs at high levels during erythrocyte differentiation in a tightly controlled and coordinated fashion. Expression of alpha-globin is a fascinatingly complex process which has been meticulously defined in several recent studies, from chromatin modifications to Pol II recruitment. Following this, alpha-globin transcripts are pro...
متن کاملHematologic Features of Alpha Thalassemia Carriers
Alpha thalassemia (α-thal) is relatively common worldwide. Most carriers are defective in either one or two alpha globin genes out of four functional ones, with deletions being more common than point mutations. The hematologic features are very important for the selection of the appropriate molecular tests while determining the genotype. The aim of this study was to compare hematologic features...
