Cation exchange-high performance liquid chromatography (CE-HPLC) is increasingly being used as a first line of investigation for hemoglobinopathies and thalassemias. Together with a complete blood count, the CE-HPLC is effective in categorizing hemoglobinopathies as traits, homozygous disorders and compound heterozygous disorders. We carried out a one year study in Apollo Hospitals, Chennai (Ta...
Beta-thalassemia and sickle cell disease (SCD) are common disorders in Turkey. Compound heterozygosity for these two disorders (betaS/beta-thalassemia) is encountered frequently. In this report we present hematological and molecular data of two Turkish siblings with betaS/beta(del)-thalassemia caused by a 290 base pair (bp) deletion and associated with increased levels of hemoglobin A2 (HbA2) a...
BACKGROUND Co-inheritance of β- and δ-globin mutations in Iran is not uncommon. This situation may interfere with correct diagnosis and genetic counseling of α- and β-thalassemia in screening programs. Here we report the co-inheritance of β- and δ-globin gene mutations in an individual with microcytosis, hypochromia and a normal hemoglobin A₂ (HbA₂) level. METHODS Genomic DNA extraction, ampl...
Mutations in human Krüppel-like factor 1 (KLF1) have recently been reported to be responsible for increased fetal hemoglobin (HbF) and hemoglobin A2 (HbA2). As increased HbF and HbA2 levels are important features of β-thalassemia, we examined whether there is any relationship between KLF1 mutation and β-thalassemia in China. For this, we first studied the incidence of KLF1 mutations in two Chin...
The inherited diseases of hemoglobin have remarkable phenotypic variability because of genetic modifiers necessitating medical intervention at various stages of disease. Genotype–phenotype relationship is crucial in this regard. So three year retrospective study of biochemical pattern of Hemoglobinopathies and Thalassemias and their clinical manifestations was done in a cohort of 689 patients i...
Mutations in human Krüppel-like factor 1 (KLF1) have recently been reported to be responsible for increased fetal hemoglobin (HbF) and hemoglobin A2 (HbA2). Because increased HbF and HbA2 levels are important features of β-thalassemia, we examined whether there is any relationship between KLF1 mutation and β-thalassemia in China. To do this, we first studied the incidence of KLF1 mutations in 2...
BACKGROUND Thalassemia syndromes are highly prevalent in Southeast Asia. In Thailand, high performance liquid chromatography (HPLC) is the most common technique routinely performed in diagnosis of thalassemia and hemoglobinopathies, while isoelectric focusing (IEF) is rarely employed. We compared the diagnostic utility of IEF and HPLC in neonatal screening for thalassemia and non-sickling hemog...
In order to investigate the contributions of visual experience vs. preprogrammed mechanisms on visual development, the current study compared contrast sensitivity in preterm vs. fullterm infants. If development is tied to time since conception, preterm infants should match the developmental trajectories of fullterm infants when plotted in postterm age. By contrast, if development is influenced ...
