What is Hgb H disease?

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.
