Hemoglobin H disease

Hemoglobin H disease is a moderate-to-severe form of alpha-thalassemia, a genetic hematologic disorder caused by the loss or inactivation of three of the four functional alpha-globin genes The condition primarily impacts the hematologic and reticuloendothelial systems, leading to chronic microcytic hypochromic hemolytic anemia, ineffective erythropoiesis, splenomegaly, and jaundice Clinical manifestations range from mild thalassemia intermedia to severe anemia with complications such as cholelit...

This deficiency produces an imbalance between alpha- and beta-globin chains, resulting in the assembly of unstable beta-globin tetramers known as hemoglobin H within erythrocytes
