Tīmeklis2024. gada 3. maijs · Fetal haemoglobin has a different quaternary structure to adult haemoglobin. Adult haemoglobin (HbA) is formed of 2 alpha subunits and 2 beta subunits. However, fetal haemoglobin contains different subunits, namely 2 alpha subunits and 2 gamma subunits. TīmeklisHereditary 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.
