WebHPFH is a disorder in which Hb F is increased above the normal adult level and there are no morphological changes to the red cells. The disorder is caused by at least 25 different mutations, either large deletions in the globin gene cluster ( Figure 71-14) or point mutations in the γ-gene promoter regions. Hereditary persistence of fetal hemoglobin (HPFH) is a benign condition in which increased fetal hemoglobin (hemoglobin F, HbF) production continues well into adulthood, disregarding the normal shutoff point after which only adult-type hemoglobin should be produced. Meer weergeven The condition is asymptomatic, and is only noticed when screening for other hemoglobin disorders.
