[MIM*142200]
normal fetal Hb (Hb F) of molecular formula α2Aγ2F, which is the major Hb component during intrauterine life, decreasing rapidly during infancy to reach a concentration of less than 0.5% in normal children and adults; the concentration of Hb F is increased in some hemoglobinopathies and in some cases of hypoplastic anemia, pernicious anemia, and leukemia; Hb F has a weaker affinity for 2,3-bisphosphoglycerate than does Hb A. More than 50 mutant variants of the γ chain have been reported.
