Translation of Human Globin mRNA: Globin Synthesis in Cells Containing Hb Leiden
Most structurally abnormal hemoglobins are present in smaller amounts than HbA in the erythrocytes of heteroxygous subjects. In the presence of a hemoglobinopathy, a and globin synthesis remains balanced with equal production of the two types of chains. In reticulocytes of subjects with Hb Leiden (fi6 or 7 glu 0) there is greater production of a than fi globin in vitro (fl/a = 0.67), and slight...

متن کاملHb in Diabetic Patients with Normal ( Hb A ) and Abnormal ( Hb S and Hb C ) Hemoglobins , as Measured
In a recent study (1 ) of diabetic patients with hemoglobins S and C (Hb S and Hb C), we showed a significant decrease in the proportion of glycosylated Hb, as measured by cation-exchange chromatography. We suggested ( I ) that these low values for glycosylated Hb might be caused by the inability of either Hb S or Hb C to undergo glycosylation or by their failure to be eluted from the column wi...
متن کاملTransient neonatal cyanosis associated with a new Hb F variant: Hb F viseu.
Neonatal cyanosis in healthy newborns can be associated either with methemoglobin due to cytochrome b5 reductase deficiency or to M-hemoglobin, a group of hemoglobin variants resulting from mutations in the globin chain genes. We report the clinical case of a neonate with cyanosis and normal cardiac and respiratory function. At birth the hematological parameters were normal; however, the methem...
متن کاملPrevalence of Hemoglobin Mutations and Hemoglobinopathies in Masjed Soleiman County, Southeastern Iran
ABSTRACT Background and Objectives: Hemoglobinopathies are characterized by defects in the synthesis of globin chains of hemoglobin (Hb). The purpose of the present study was to evaluate mutations associated with thalassemia and other hemoglobinopathies in Masjed Soleiman County, Iran. Methods: This descriptive study was carried out on 456 individuals suspected of ha...
