Fanconi Anemia
What is Fanconi Anemia?
Fanconi anemia is a rare inherited disorder that affects your bone marrow. Bone marrow is the soft tissue inside your bones that makes new blood cells. When you have Fanconi anemia, your bone marrow slowly loses its ability to produce enough healthy blood cells.
This condition is genetic, meaning you inherit it from your parents. It affects red blood cells that carry oxygen, white blood cells that fight infection, and platelets that help blood clot. Most people with Fanconi anemia are diagnosed in childhood, though some cases appear later in life.
Fanconi anemia is progressive, which means it gets worse over time. People with this condition face higher risks for blood cancers and bone marrow failure. Early detection through blood testing helps doctors monitor the condition and plan appropriate care.
Symptoms
- Easy bruising or bleeding that takes longer to stop
- Frequent infections or illnesses
- Unusual tiredness or weakness
- Pale skin or looking unusually pale
- Shortness of breath during normal activities
- Small head size or slow growth in children
- Skin patches with unusual coloring
- Thumb or arm abnormalities present at birth
- Kidney or heart defects
- Frequent nosebleeds
Some people with Fanconi anemia have very mild symptoms early on. Others may not show blood-related symptoms until their teenage years or later. Physical differences present at birth can sometimes signal the condition before blood problems appear.

Causes and risk factors
Fanconi anemia happens when you inherit faulty genes from both parents. At least 22 different genes can cause this condition when they contain mutations. These genes normally help repair damaged DNA in your cells. When the genes do not work properly, cells cannot fix DNA damage. This leads to chromosome instability and causes bone marrow cells to die or stop working correctly.
Risk factors include having parents who both carry a Fanconi anemia gene mutation. The condition affects all ethnic groups but is more common in certain populations. Ashkenazi Jewish, Spanish Romani, and South African Afrikaner communities have higher carrier rates. If both parents carry one mutated gene, each child has a 25 percent chance of developing Fanconi anemia.
How it's diagnosed
Doctors diagnose Fanconi anemia through specialized genetic tests and blood tests. The chromosome breakage test is the gold standard for diagnosis. This test exposes your cells to certain chemicals to see if chromosomes break more easily than normal. Genetic testing can identify which specific gene mutation is causing the condition.
Blood tests help monitor disease progression once diagnosed. Platelet count shows how well your bone marrow is making platelets, which decline as bone marrow failure advances. Red Cell Distribution Width or RDW measures variation in red blood cell size, which increases due to abnormal cell production and bone marrow stress. Rite Aid offers testing that includes these key biomarkers to help monitor blood cell health over time.
Treatment options
- Regular blood tests to monitor blood cell counts and disease progression
- Blood transfusions to replace red blood cells or platelets when counts drop too low
- Androgen therapy medications to stimulate bone marrow blood cell production
- Growth factors that encourage bone marrow to make more blood cells
- Bone marrow transplant, which is currently the only cure for the blood-related problems
- Cancer screening since people with Fanconi anemia have higher cancer risk
- Avoiding substances that damage DNA like tobacco smoke and excessive sun exposure
- Eating a nutrient-rich diet to support overall health and blood cell production
- Genetic counseling for family planning decisions
- Regular visits with a hematologist who specializes in blood disorders

Frequently asked questions
Life expectancy varies widely depending on treatment and complications. Without a bone marrow transplant, median survival is around 30 years. Successful bone marrow transplants can significantly improve outcomes and extend life. Regular monitoring and early intervention for complications are important for better long-term health.
Most doctors recommend blood tests every 3 to 6 months to monitor blood cell counts. More frequent testing may be needed if your counts are dropping or if treatment changes. Regular testing helps catch problems early before they become serious. Your hematologist will create a monitoring schedule based on your specific situation.
Yes, genetic testing can identify Fanconi anemia before blood problems develop. Families with a known history can test children early. Some physical abnormalities present at birth may prompt doctors to test for the condition. Early detection allows for better monitoring and planning of care.
Declining platelet counts below 150,000 per microliter signal worsening bone marrow function. Dropping red blood cell counts that cause anemia are also warning signs. White blood cell counts below 1,500 per microliter increase infection risk. Rising RDW values indicate more variation in blood cell size, which reflects bone marrow stress.
Yes, bone marrow transplant is currently the only treatment that can cure the blood-related problems of Fanconi anemia. The procedure replaces damaged bone marrow with healthy donor cells. However, transplants carry risks and do not prevent other complications like cancer susceptibility. The decision to pursue transplant depends on individual health factors and donor availability.
You cannot stop the genetic condition itself, but you can slow progression and reduce complications. Avoid tobacco, alcohol, and excessive sun exposure, which damage cells. Eat a balanced diet rich in vitamins and minerals. Stay current with medical appointments and blood monitoring to catch problems early.
People with Fanconi anemia have much higher risks for leukemia, especially acute myeloid leukemia. Solid tumors of the head, neck, esophagus, and reproductive organs are also more common. Skin cancer risk is elevated due to DNA repair problems. Regular cancer screening is an important part of long-term care.
Yes, siblings should be tested for Fanconi anemia and carrier status. Each sibling has a 25 percent chance of having the condition and a 50 percent chance of being a carrier. Testing helps identify cases early and provides important information for family planning. Siblings may also be potential bone marrow donors if their tissue type matches.
Avoid medications that suppress bone marrow or damage DNA when possible. These include certain antibiotics, chemotherapy drugs, and some anti-seizure medications. Always tell doctors and dentists about your Fanconi anemia before starting new medications. Your hematologist can review any prescribed drugs to ensure they are safe for you.
Pregnancy with Fanconi anemia carries risks due to low blood counts and increased stress on the body. Some women have successful pregnancies with close medical monitoring and support. Blood transfusions may be needed during pregnancy. Genetic counseling before pregnancy helps families understand inheritance risks and make informed decisions.
