Major Signs and Symptoms
Your doctor may suspect you or your child has Fanconi anemia (FA) if you have signs and symptoms of:
Because FA is an inherited disorder, children may be tested if one of their brothers or sisters has FA.
If you have anemia, you have a lower than normal number of healthy red blood cells. This means that your blood isn't able to get enough oxygen to your body's cells.
The most common symptom of anemia is fatigue (feeling tired or weak). If you have anemia, it may seem hard to find the energy to do normal activities.
Other symptoms include shortness of breath, dizziness, headache, coldness in the hands and feet, pale skin, and chest pain.
Bone Marrow Failure
When your bone marrow fails, it can't make enough of the three types of blood cells that your body needs to work normally: red blood cells, white blood cells, and platelets. This can cause many problems that have various signs and symptoms.
With too few red blood cells, you can develop anemia. In FA, the size of your red blood cells also can be much larger than normal. This makes it harder for these cells to work well.
With too few white blood cells, you're at risk for infections. Infections may last longer and be more serious than in people who don't have FA.
With too few platelets, you may bleed and bruise easily, suffer from internal bleeding, or have petechiae (pe-TEE-kee-ay). Petechiae are tiny red spots caused by bleeding in small blood vessels just below your skin.
In some people who have FA, the bone marrow makes a lot of harmful, immature white blood cells called blasts. These blasts don't work like normal blood cells. As they build up in the bone marrow, they block the production of normal blood cells.
A large number of blasts in the bone marrow can lead to a type of blood cancer called acute myeloid leukemia (AML).
Many birth defects can be signs of FA. These include:
