Also known as: hemoglobin H disease.
Hemoglobin H disease is a form of alpha thalassemia, a medical condition in which the body makes less hemoglobin than usual. There are four genes that contribute to the making of hemoglobin. When a person has a problem with three of these genes, the body begins to make an abnormal form of hemoglobin known as hemoglobin H, which can cause blood flow problems and anemia.
Hemoglobin H is a genetic disease, and the abnormal genes are passed along from parents to their children. A person must receive the genes from both parents in order to develop Hgb H disease.
Possible symptoms of Hgb H disease include anemia, jaundice, gallstones, growth retardation and an increased risk of infections.
Hgb H disease can be severe. Many people with the disease require regular blood transfusions and iron chelation in order to live a healthy life.
