The beta-globin locus control region (LCR) is a powerful regulatory element required for high-level globin gene expression. We have generated transgenic mouse lines carrying a beta-globin locus yeast artificial chromosome lacking the LCR to determine if the LCR is required for globin gene activation. beta-Globin gene expression was analyzed by RNase protection, but no detectable levels of epsil...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 β-thalassemia (cooley anemia) initially was described by dr cooley. [1] it is recognized that various types of thalassemia are inherited anemia caused by mutations at the globin gene, affecting the production of é‘ - or β-globin protein. the anemia interferes with red cell maturation. [2] β-globin gene mutations give rise ...

High-level induction of fetal ( ) globin gene expression for therapy of -hemoglobinopathies likely requires local chromatin modification and dissociation of repressor complexes for -globin promoter activation. A novel -globin– inducing short-chain fatty acid derivative (SCFAD), RB7, which was identified through computational modeling, produced a 6-fold induction in a reporter assay that detects...

beta thalassemia is the  most common autosomal recessive disorder. the present study reports a rare β globin gene mutation, hbb: c.180g>a: codon 59 (aag/aaa), in a patient from gilan province, northern iran. nucleotide sequencing of amplified dna belonging to a 35 years old man presenting mild hypochromia revealed a synonymous mutation due to a g>a conversion at the third position of codon 59 o...

This is a report of couple with abnormal hematological indices who were investigated for α & β-thalassemia mutations. Based on CBC and capillary hemoglobin electrophoresis results, the male female subjects β α-thalassemia carriers, respectively. Multiplex-Gap-PCR Sanger sequencing techniques used identification mutations β-globin genes. The DNA test showed presence c.315 + 1 G > A mutati...

Here we report the first case of unstable hemoglobin Hakkari identified in Russia to our knowledge. It was diagnosed a two-year-old Russian boy with severe transfusion-dependent anemia caused by de novo mutation b-globin gene [b31(B13) Leu→Arg, HBB: c.95T>G]. Routine diagnostic methods were not effective, and his diagnosis established until sequencing globin performed. A comparative analysis...

Introduction: Beta-thalassemia is characterized by absence or reduced synthesis of the β-globin. Carriers of β-thalassemia, typically have microcytic hypochromic anemia and elevated hemoglobin HbA2 and normal HbF level. On the other hand carriers of severe alpha-thalassemia also have similar CBC parameters to that of β-thalassemia with normal HbA2 level. Co-presence of mutations in the β-globin...

In order to study the relationships among mammalian alpha-globin genes, we have determined the sequence of the 3' flanking region of the human alpha 1 globin gene and have made pairwise comparisons between sequenced alpha-globin genes. The flanking regions were examined in detail because sequence matches in these regions could be interpreted with the least complication from the gene duplication...
