Regulation of the beta- and delta-hemoglobin genes. A family with hereditary persistent fetal hemoglobin and beta-thalassemia. 1976

H Rothschild, and J Bickers, and R Marcus

We have studied a 41-year-old black male with the simultaneous occurrence of hereditary persistence of fetal hemoglobin (HPFH) and beta-thalassemia, and his two postadolescent sons, each heterozygous for one of the traits. The son heterozygous for beta-thalassemia had an elevated Hb A2, but the index case did not. The data from this pedigree indicate that the delta-allele trans to the beta-thalassemia gene was reponsible for the increased delta-chain production. Evidence from other cases of combination HPFH and beta-thalassemia indicates that regulation of the beta- and delta-chain production in beta-thalassemia is heterogeneous with respect to mechanism.

D008297 Male Males
D005319 Fetal Hemoglobin The major component of hemoglobin in the fetus. This HEMOGLOBIN has two alpha and two gamma polypeptide subunits in comparison to normal adult hemoglobin, which has two alpha and two beta polypeptide subunits. Fetal hemoglobin concentrations can be elevated (usually above 0.5%) in children and adults affected by LEUKEMIA and several types of ANEMIA. Hemoglobin F,Hemoglobin, Fetal
