WebBy Ashutosh Lal, MD. Hemoglobin H disease (HbH) is a form of alpha thalassemia in which moderately severe anemia develops due to reduced formation of alpha globin chains. In this condition, as in the other forms of thalassemia, there is an imbalance of globin chains needed to form hemoglobin. Normally, there are four genes to produce alpha ... WebAbnormal hemoglobins → Hb variants. The hemoglobinopathies encompass a heterogenous group of disorders associated with genetic mutations in either the ß-, ά-, γ-, or δ- chains. Hereditary abnormalities of the ß globin chain are the most common cause Ex Hb S- most common variant. Caused by ß-chain abnormality. Abnormalities of the ά, γ ...
