Does your child feel tired all the time? Do you have any doubts about his or her development? Or does it sometimes take a while for even a small cut to stop bleeding? It's normal for a mother or father to feel scared when they see things like this. Today we're going to talk about a rare condition that many people haven't even heard of, but it's very important to know about. That's Fanconi Anemia (FA) . Although the name may sound a bit strange, let's talk about it simply, in a way that you can understand.
Simply put, what is Fanconi anemia (FA)?
Fanconi anemia, or FA for short, is a rare inherited condition . It mainly affects your bone marrow . Now you might be wondering what this bone marrow is all about.
Think of the bone marrow as a sponge-like part inside the large bones of our body. It's like our body's blood-making factory. This factory makes three main types of cells that our body needs:
- Red blood cells: The workers that carry oxygen throughout the body.
- White blood cells: Our body's army that fights diseases and germs.
- Platelets: Little workers that stop bleeding and clot blood when there is an injury.
Now, in a person with FA, the bone marrow, the factory, does not work properly. This means that it cannot make enough healthy blood cells. We call this bone marrow failure . This can cause many problems in the body. Also, this disease can affect other parts of the body and the appearance of the body.
How does FA affect my or my child's body?
The way FA affects each person can vary, but in general, it can be affected in three main ways.
1. Physical Abnormalities: About 75% of children born with FA have some form of physical abnormality. Some of these may be visible (for example, changes in the hands and thumbs), while others may involve internal organs.
2. Bone Marrow Failure: This condition occurs in about 90% of FA patients. This means that the bone marrow gradually stops producing healthy blood cells. This can lead to anemia conditions such as aplastic anemia and a condition called myelodysplastic syndrome (MDS) . MDS is also considered a pre-leukemia.
3. Increased Cancer Risk: People with FA are at higher risk of developing some types of cancer than the general population. In particular, there is an increased risk of developing blood-related cancers such as leukemia and cancers of the head, neck, and skin. Between 10% and 30% of these people may develop some type of cancer.
The important thing is that not all of these symptoms occur in every patient. Some people may have many of these symptoms, while others may have only very few symptoms.
So is FA a cancer?
This is a problem that many people have. No, FA is not cancer. However, because it is a genetic disease, the body's ability to repair damaged cells is reduced. Therefore, over time, these damaged cells are at greater risk of becoming cancerous. Simply put, FA is a condition that can pave the way for cancer, but it is not cancer itself.
What are the symptoms of FA disease?
Because FA affects different people differently, the symptoms can vary greatly. Some people can go for years without any obvious symptoms. Let's break these symptoms down into a few main categories.
| 1. Symptoms associated with Anemia | |
|---|---|
| Frequent feeling of extreme fatigue | Feeling so tired that you can't even do normal tasks, and feeling sleepy all the time. |
| Pale skin | Pale skin, lips, and under the eyes due to lack of blood in the body. |
| Difficulty breathing | Feeling short of breath even with slight exertion, such as climbing stairs. |
| Heart palpitations | Feeling like your heart is beating too fast. |
| Frequent headaches | Headaches can be caused by a decrease in the amount of oxygen needed by the brain. |
| 2. Symptoms associated with bone marrow failure | |
|---|---|
| Frequent illness | A low white blood cell count reduces the body's immunity, which can lead to frequent bacterial and fungal infections. |
| Bleeding and bruising | Due to low platelets, even a small wound will not stop bleeding. You may bleed from your gums and nose. You may even develop blue bruises on your body. |
| 3. Characteristics related to physical changes | |
|---|---|
| Changes in hands and fingers | An abnormal shape of the thumb, having two thumbs on one hand, or having no thumb at all. |
| Growth retardation | Not having a height or weight appropriate for age. Being smaller than average. |
| Head size changes | The head is abnormally small (microcephaly) or abnormally large (hydrocephaly) . This can affect the child's growth, speech, and walking. |
| Skin spots | Large, light brown spots on the skin. These are also called "café-au-lait" spots, which look like spots that look like coffee with milk. |
| Other features | Hearing impairment, abnormal shape of the ears, curvature of the spine (scoliosis) , certain kidney or heart problems. |
Why does this FA situation occur?
This is caused by a defect in our genes . Think of genes as the blueprint for building our bodies. There are about 20 genes involved in FA. The main function of these genes is to repair damage to our DNA .
Throughout our lives, due to things in our environment and the food we eat, the DNA in our body's cells gets damaged a little bit. That's normal. The proteins made by the FA genes work like a repair team, fixing this damaged DNA.
However, because a person with FA has a mutation in these genes, the repair team doesn't work properly. What happens then?
- DNA damage is accumulating.
- This causes cells to begin to divide abnormally (which can lead to cancer) or cells to die.
- The bone marrow weakens and physical changes occur as cells die.
This is something that is inherited from parents to children. If both parents are carriers of this defective gene, there is a 25% chance that their child will develop FA.
How do doctors diagnose FA?
FA is often diagnosed during treatment or testing for another condition (such as anemia or cancer). Your doctor will carefully examine your or your child's symptoms and recommend several tests if FA is suspected.
Commonly performed tests:
- Complete Blood Count (CBC): This measures the number of red cells, white cells, and platelets in the blood. It can check for any low levels of these.
- Bone Marrow Biopsy: A small sample of bone marrow is taken and examined under a microscope to see how the cells are forming and what problems they have.
- MRI and Ultrasound Scans: These tests help to see if there are any changes in the organs inside the body (such as the kidneys and heart).
Specific tests to confirm FA:
- Chromosome Breakage Test: This is the main test used to diagnose FA. In this test, a chemical is added to cells in a blood sample and the chromosomes are checked for damage or breakage. The chromosomes in the cells of a person with FA are damaged much more quickly than in a normal person.
- Genetic Screening: This test can identify the specific genetic defect that causes FA.
Can I get tested during pregnancy?
Yes. If someone in your family has FA, your baby can be tested for the condition during pregnancy. This can be done using tests such as amniocentesis or chorionic villus sampling . You can talk to your doctor about this to find out more.
What are the treatments for FA?
The main goal of doctors when treating FA is to control symptoms and manage complications.
- Bone Marrow Transplant: This is the only curative treatment for blood problems caused by FA. In this, the patient's defective bone marrow is destroyed and bone marrow from a healthy, compatible donor is returned to the patient.
- Androgen Therapy: These are a type of hormone. These medications stimulate the bone marrow to help increase the production of red blood cells and platelets.
- Synthetic Growth Factors: These are given as injections and help increase the production of white blood cells and red blood cells from the bone marrow.
- Surgery: Surgery may be necessary to correct physical changes (for example, a problem with the big toe) or to repair damaged organs.
The most important thing is that the doctor who examines you will decide what treatment is best for you or your child. So be sure to follow the doctor's instructions.
Living with FA and things to watch out for
FA is a lifelong condition that must be managed, so it is important to constantly monitor your health.
- Cancer risk: Since FA increases the risk of cancer, smoking and alcohol consumption should be completely avoided . Also, since the risk of skin cancer is high, you should protect your skin by using a good sunscreen and wearing a hat when going out in the sun. Be aware of new spots and lumps on the skin.
- Bleeding: Avoid sports and activities that can cause injury due to low platelet count. Use a soft toothbrush when brushing your teeth. If you experience any bleeding or bruising, notify your doctor immediately.
- Regular medical checkups: Attend regular checkups as prescribed by your doctor. It is essential to get blood tests and cancer screenings done on time.
Do I still need to be concerned about these things after a successful bone marrow transplant?
Yes, absolutely. Although a bone marrow transplant can cure the blood diseases caused by FA, the FA genetic defect is still present in other cells of the body. Therefore, the risk of developing cancer in places such as the head, neck, and skin remains. Therefore, it is very important to be under medical supervision for the rest of your life even after the transplant.
Take-Home Message
- Fanconi anemia (FA) is not cancer, but it is a rare, inherited genetic disease that increases the risk of cancer.
- This disease mainly affects the bone marrow, reducing the production of healthy blood cells.
- Common symptoms include frequent fatigue, paleness, frequent illness, and easy bleeding or bruising.
- Bone marrow transplantation is the best treatment for the blood-related problems of this disease. But even after transplantation, lifelong medical monitoring is essential due to the risk of cancer.
- If you or your child has these symptoms or has a family history, do not panic and see your doctor immediately for advice.
