Fetal hemoglobin heterogeneity in Brazilian newborns and beta-thalassemia homozygotes

M A Zago


The gamma chain composition of HbF in 37 beta-thalassemia homozygotes and 85 unselected newborn babies from Brazil was studied by high performance liquid chromatography (HPLC). The G gamma value of 59.5 +/- 7.5% (mean +/- SD) obtained for the beta-thalassemia homozygotes was significantly lower than the newborn value of 71.2 +/- 4.2%. The A gamma T gene frequency was 0.159 for the newborns and 0.454 for the thalassemia homozygotes. The A gamma T gene occurred both in chromosomes bearing the beta(0)-thalassemia gene and those with the beta(+)-thalassemia gene.

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
