There is no red cell effect with Ho-2 compared to Hemoglobin S, which changes the shape of the cell to become sickled. The Hopkins-2 variant of hemoglobin is not involved in forming sickle cells. There is a lack of phenotypic expression of Ho-2 in terms of sickle cell, so a person with sickle cell and hemoglobin Hopkins-2 would be asymptomatic.

Hairy cell leukemia is an uncommon hematological malignancy characterized by an accumulation of abnormal B lymphocytes. It is usually classified as a subtype of chronic lymphocytic leukemia (CLL). Hairy cell leukemia makes up about 2% of all leukemias , with fewer than 2,000 new cases diagnosed annually in North America and Western Europe combined.
Sickle cell anemia is an autosomal recessive genetic condition where the beta-globin protein subunit of hemoglobin is misshapen, which ultimately leads to a sickle-shaped red blood cell, which is prematurely destroyed and can get stuck in small blood vessels. This video discusses the pathophysiology, clinical signs and symptoms, and treatment ...
Hemoglobin A (HbA), also known as adult hemoglobin, hemoglobin A1 or α2β2, is the most common human hemoglobin tetramer, accounting for over 97% of the total red blood cell hemoglobin. [1] Hemoglobin is an oxygen-binding protein, found in erythrocytes, which transports oxygen from the lungs to the tissues. [2]
