WebMar 21, 2024 · The two types of gamma chains differ at residue 136 where glycine is found in the G-gamma product (HBG2) and alanine is found in the A-gamma product (HBG1). The former is predominant at birth. The order of the genes in the beta-globin cluster is: 5'-epsilon -- gamma-G -- gamma-A -- delta -- beta--3'. [provided by RefSeq, Jul 2008] WebThalassemia patients with persistently high levels of fetal globin typically have less severe anemia, have milder clinical syndromes, and are often transfusion independent. Therefore, the search for molecules exhibiting the property of inducing gamma-globin gene expression and fetal hemoglobin (HbF) production is of great interest.
