Clinical hemoglobin C
Hemoglobin C disease is a blood disorder passed down through families. It leads to a type of anemia, which occurs when red blood cells break down earlier than normal.
Hemoglobin C is an abnormal type of hemoglobin, the protein in red blood cells that carries oxygen. It is a type of hemoglobinopathy. The disease is caused by a problem with a gene called beta globin.
The disease most often occurs in African Americans. You are more likely to have hemoglobin C disease if someone in your family has had it.
Most people do not have symptoms. In some cases, jaundice may occur. Some people may develop gallstones that need to be treated.
Exams and Tests
A physical exam may show an enlarged spleen.
Tests that may be done include:
In most cases, no treatment is needed. Folic acid supplements may help your body produce normal red blood cells and improve the symptoms of the anemia.
People with hemoglobin C disease can expect to lead a normal life.
Complications may include:
- Ggallbladder disease
- Enlargement of the spleen
When to Contact a Medical Professional
