What is another word for hereditary persistence of fetal hemoglobin?
Pronunciation: [hɪɹˈɛdɪtəɹi pəsˈɪstəns ɒv fˈiːtə͡l hˈiːməɡlˌɒbɪn] (IPA) 
Hereditary persistence of fetal hemoglobin is a medical condition where an individual continues to produce fetal hemoglobin (HbF) beyond infancy and into adulthood. To simplify the terminology, one may refer to the condition as HbF persistence or simply fetal hemoglobin retention. The excess production of HbF can be caused by various genetic mutations and can lead to conditions such as sickle cell anemia, thalassemia, and other hemoglobinopathies. Some research studies also use the term "fetal hemoglobin switch" to refer to the process of transitioning from HbF to adult hemoglobin (HbA), which is typically completed within the first few months of life.
