Fanconi Anaemia in Children

Fanconi Anaemia (FA) is a rare inherited blood disorder in which the bone marrow fails to produce enough blood cells. It primarily affects children, and without the right diagnosis and timely treatment, it can lead to life-threatening bone marrow failure or blood cancer.

The good news is that with early detection and the right specialist, many children with Fanconi Anaemia go on to live healthy, full lives. A bone marrow transplant, when done at the right time, can permanently correct the bone marrow failure.

Dr. Satyendra Katewa, a Pediatric Haemato-Oncologist and BMT doctor at Max Healthcare, Patparganj, Delhi, has extensive experience in diagnosing and treating Fanconi Anemia in children using child-specific protocols.

What Is Fanconi Anaemia in Children?

Fanconi Anaemia is a genetic condition that affects the body’s ability to repair damaged DNA. As a result, blood-forming cells inside the bone marrow cannot survive, and over time, the bone marrow fails to produce enough:

• Red blood cells – causing anaemia and fatigue
• White blood cells – making the child prone to frequent infections
• Platelets – leading to easy bruising 

When all three are low together, a condition called pancytopenia signals bone marrow failure. Fanconi Anaemia is the most common inherited cause of aplastic anaemia in children, and it requires a very different treatment approach from other causes of low blood counts.

What Causes Fanconi Anaemia in Children?

Fanconi Anaemia is a rare inherited condition caused by changes in certain genes that help the body repair damaged cells and maintain healthy bone marrow.

It is usually passed down from both parents, even when the parents themselves are completely healthy and have no symptoms.

This means:

• Both parents silently carry the condition
• With each pregnancy, there is a 1 in 4 (25%) chance that the child may develop Fanconi Anaemia
• Brothers and sisters should also be tested after diagnosis, as they may have the condition or could be a suitable bone marrow donor.

Signs and Symptoms of Fanconi Anaemia in Children

Fanconi Anaemia presents in two ways: physical features that may be visible from birth, and blood-related symptoms that develop as the bone marrow begins to fail, typically between ages 5 and 15, with the average age of bone marrow failure around 7 to 8 years.

Physical Features (Present from Birth in ~75% of Cases)

• Missing, extra, or malformed thumbs 
• Short stature and low birth weight
• patchy skin darkening
• Kidney abnormalities (often found incidentally on ultrasound)
• Small head size, small or abnormal eyes
• Hearing loss due to ear abnormalities
• Heart defects in some cases

Important: Around 25% of children with Fanconi Anaemia have no visible physical features at all. In these children, the diagnosis only becomes apparent when blood counts begin to fall.

Blood-Related Symptoms (Bone Marrow Failure Signs)

• Persistent tiredness and pale skin
• Frequent infections 
• unexplained bruising
• Nosebleeds 
• Tiny red or purple pinprick spots on the skin (petechiae) 
• Shortness of breath during mild activity
• Poor growth or failure to thrive in younger children

If your child has several of these symptoms together, particularly fatigue, pallor, unusual bruising, and recurrent infections, seek specialist review. These are signs that the bone marrow may be under serious stress.

How Is Fanconi Anemia Diagnosed?

A routine blood count is often the first clue, but confirming FA requires specific specialist tests.

Complete Blood Count (CBC) – Reveals low red cells, white cells, and platelets. When all three are simultaneously low (pancytopenia), a bone marrow failure condition is suspected.

Chromosomal Breakage Test (DEB/MMC Test) – The chromosome breakage test (also called the DEB test) is the gold standard test for diagnosing Fanconi Anaemia. In this test, blood cells are exposed to special chemicals that damage DNA. In children with Fanconi Anaemia, chromosomes break much more easily than in normal cells because the body cannot repair DNA properly.

Bone Marrow Biopsy – Assesses how severely the marrow is affected and whether pre-leukemic changes are developing.

HLA Typing – Tissue matching of the patient and all siblings is done after diagnosis to identify whether a matched sibling donor is available for bone marrow transplant.

Since FA can affect multiple organs, the specialist may also arrange a kidney ultrasound, heart evaluation, hearing test, ophthalmology review, and endocrine tests.

Fanconi Anaemia vs Aplastic Anaemia

The conditions of Fanconi anaemia and aplastic anaemia are among the most common points of confusion, and understanding the difference matters enormously for treatment:

Using standard aplastic anaemia treatment on a child with FA can cause serious harm. This is why the chromosomal breakage test is not optional; it is essential before any treatment decision is made.

Treatment Options for Fanconi Anaemia in Children

Treatment depends on the severity of bone marrow involvement, the child’s age, the mutated gene, and whether a suitable donor is available.

Monitoring in Mild Cases

When blood counts are only mildly reduced, and the marrow is still functioning adequately, regular monitoring may be the right first step, with blood counts every 1 to 3 months and annual bone marrow assessment. This phase also allows time for sibling HLA typing and donor identification.

Supportive Care

Used to manage symptoms while planning definitive treatment:

• Blood transfusions for severe anaemia
• Platelet transfusions to reduce bleeding risk
• Antibiotics and antifungals for infection management
• Iron chelation therapy is required if frequent transfusions have caused iron buildup

Androgen Therapy

Male hormones can improve blood counts in around 50% of FA children in the short term by stimulating the bone marrow. They do not cure FA; they are used as a bridge to transplant when it cannot be done immediately. Liver function must be monitored closely throughout.

Bone Marrow Transplant – The Only Curative Treatment

A bone marrow transplant (BMT), also called a hematopoietic stem cell transplant (HSCT), is the only treatment that can permanently correct bone marrow failure in Fanconi Anaemia. Healthy stem cells from a matched donor replace the failing marrow, and once they engraft, the child’s body can produce normal blood cells again.

BMT is recommended when:

• Moderate to severe bone marrow failure develops
• Early leukaemic changes appear in the bone marrow
• Blood counts are falling rapidly despite other treatment
• A suitable donor is identified, and the child is otherwise stable

Why does BMT for Fanconi Anaemia require specialist expertise

Children with Fanconi Anemia are extremely sensitive to standard chemotherapy used before a bone marrow transplant. Their bodies cannot repair DNA damage normally so regular transplant medicines can cause serious side effects and organ damage.

Specialist FA transplant centres use gentler, reduced-intensity treatment protocols designed specifically for these children. Choosing a transplant team experienced in Fanconi Anemia is very important for safer outcomes.

Donor options:

• Matched Sibling Donor (MSD) 
• Matched Unrelated Donor (MUD) 
• Haploidentical Family Donor

Dr. Satyendra Katewa performs paediatric bone marrow transplants and stem cell transplants in Delhi across all donor types using FA-specific reduced-intensity protocols. Your specialist will discuss realistic outcomes based on your child’s specific situation, donor availability, and disease stage.

Long-Term Monitoring After Fanconi Anaemia Treatment

Even after a successful bone marrow transplant, children with Fanconi Anaemia still need lifelong follow-up care. This is because some parts of the body may still have difficulty repairing damaged cells, increasing the risk of certain cancers later in life.

Regular yearly check-ups, blood tests, and specialist evaluations are recommended for better long-term health.

In some children, conditions such as leukaemia may still develop and may require additional treatment such as chemotherapy or targeted therapy. If leukaemia develops, chemotherapy or targeted therapy may be part of the treatment plan. Read more about blood cancer in children and Acute Myeloid Leukaemia (AML).

Bone Marrow Transplant Cost for Fanconi Anaemia in India
