Qualitative hemoglobinopathies
WebHemoglobinopathies are a group of autosomal recessive disorders that can be broadly categorized into two major groups: thalassemias and structural variants of hemoglobin. However, hereditary persistence of fetal hemoglobin (Hb F), a relatively benign condition, can also be considered as hemoglobinopathy. WebJul 21, 2014 · These mutations can be divided into two distinct types: • Those that cause qualitative abnormalities (e.g. sickle cell anemia) and those that cause quantitative abnormalities (the thalassemias). Taken together these disorders are referred to as the hemoglobinopathies.
