The gamma chain heterogeneity of fetal hemoglobin in black beta-thalassemia and HPFH heterozygotes.
High pressure liquid chromatography (HPLC) was applied to the HbF isolated from blood of numerous black patients with beta-thalassemia trait or homozygosity, G gamma-delta beta-thalassemia trait, G gamma A-gamma HPFH heterozygosity, or the G gamma-[delta+ beta+]-HPFH condition. The method allowed an accurate evaluation of the relative quantities of three types of gamma-chain (G gamma, A gamma I...
متن کاملSimvastatin and t-butylhydroquinone suppress KLF1 and BCL11A gene expression and additively increase fetal hemoglobin in primary human erythroid cells.
UNLABELLED Although increased fetal hemoglobin (HbF) levels have proven benefit for people with β-hemoglobinopathies, all current HbF-inducing agents have limitations. We previously reported that drugs that activate the NRF2 antioxidant response signaling pathway increase HbF in primary human erythroid cells. In an attempt to increase HbF levels achieved with NRF2 activators, in the present stu...
متن کاملCompound heterozygosity for KLF1 mutations associated with remarkable increase of fetal hemoglobin and red cell protoporphyrin.
The persistence of high fetal hemoglobin level in adults may ameliorate the clinical phenotype of beta-thalassemia and sickle cell anemia. Several genetic variants responsible for hereditary persistence of fetal hemoglobin, linked and not linked to the beta globin gene cluster, have been identified in patients and in normal individuals. Monoallelic loss of KLF1, a gene with a key role in erythr...
متن کاملTen novel mutations in the erythroid transcription factor KLF1 gene associated with increased fetal hemoglobin levels in adults.
We investigated whether mutations in the KLF1 gene are associated with increased Hb F levels in ethnically diverse patients referred to our laboratory for hemoglobinopathy investigation. Functionally effective KLF1 mutations were identified in 11 out of 131 adult samples with an elevated Hb F level (1.5-25.0%). Eleven different mutations were identified, 9 of which were previously unreported. K...
متن کاملKLF1 gene and borderline hemoglobin A2 in Saudi population
Introduction Elevated HbA2 (hemoglobin A2) level is considered the most reliable hematological parameter for the detection of β-thalassemia carriers. However, some carriers are difficult to recognize because the level of HbA2 is not in the distinctive carrier range, i.e. 4.0-6.0%; instead, some carriers have HbA2 levels between normal and carrier levels, i.e. borderline HbA2 (HbA2 = 3.1-3.9%). ...
