Does your child often get colds, coughs, ear infections, or skin infections? Does one illness get better before another? Usually, we think that the child's immunity is a little low and that he is catching diseases at school and in play areas. However, in very rare cases, this can be caused by a specific genetic condition called WHIM Syndrome . Although this is not talked about much, it is very important to be aware of it.
What is this WHIM syndrome?
Simply put, WHIM syndrome is a very rare genetic disease that affects our body's immune system. The name WHIM is derived from the first letters of the four main symptoms of the disease.
- Warts (warts)
- Hypogammaglobulinemia (low levels of antibodies in the blood)
- Infections (frequent infections)
- Myeloalveolar hemorrhage (white blood cell congestion in the bone marrow)
Imagine that our body has an army of white blood cells. The job of these soldiers is to fight off enemies like bacteria and viruses that cause disease. In someone with WHIM syndrome, the most important soldiers in this army, called neutrophils , get stuck in their base, the bone marrow. They can't get out, into the bloodstream, to fight disease. So, the body's defense system is weakened, and they start getting sick more often.
It's so rare that it's believed to affect only one in 5 million births, so you may not have heard of it before.
What are the symptoms of WHIM syndrome?
These symptoms can vary greatly from person to person. Some people have very mild symptoms. Others can develop severe infections that can be life-threatening. These symptoms usually begin in childhood, but sometimes the disease can go undiagnosed until adulthood.

Especially about warts and cancer risk
Many people around us can be infected with the human papillomavirus (HPV), which causes warts. However, in a person with a healthy immune system, this virus disappears from the body almost automatically. However, because the immune system of a person with WHIM syndrome is weak, it is difficult to fight this HPV virus. Therefore, the virus remains in the body for a long time, causing warts, and in some cases, increasing the risk of cancer.
What causes this? Is this contagious?
The main cause of WHIM syndrome is a mutation in the gene called `CXCR4` in our body. Think of this gene as a program that instructs our cells. When this gene changes, the aforementioned white blood cells (Neutrophils) stop coming out of the bone marrow.
Because this is a genetic condition, it cannot be spread from person to person through sneezing or touching . However, it can be passed from parents to children. If either parent has this gene mutation, each child they have has a 50% chance of inheriting the condition .
How do you accurately diagnose this disease?
Because this is such a rare disease, it's hard to diagnose with just one test. Your doctor will carefully examine you and your child's symptoms, how often they get infections, and may then recommend several tests.
- Complete Blood Count (CBC): This checks for low white blood cells, especially neutrophils, in the blood.
- Antibody test (Immunoglobulin G - IgG blood test): This test is done to check for low levels of antibodies that fight infection.
- Bone Marrow Biopsy: In this procedure, a small sample of bone marrow is taken from the hip bone under mild anesthesia and examined under a microscope. This can accurately determine if white blood cells are trapped in the bone marrow (myelokathexis).
- Genetic Testing: This test can confirm whether there is a mutation in the `CXCR4` gene that causes WHIM syndrome.
The sooner the disease is diagnosed, the less likely it is to develop complications such as frequent hospitalizations, hearing loss, and lung damage.
What are the treatments for WHIM syndrome?
There is no cure for this condition yet. However, there are several treatments that can help control symptoms, protect against infections, and help you live a normal life.
Types of drugs
- Xolremdi: This is a new drug approved in 2024. It helps release white blood cells that are stuck in the bone marrow. This can reduce the risk of infection by about 40%.
- G-CSF treatment: This is a shot. It stimulates the bone marrow and helps it produce more white blood cells.
- IgG therapy: For those with low antibody levels, the immune system is strengthened by administering antibodies from outside.
- Antibiotics: When bacterial infections (such as pneumonia, skin infections) develop, your doctor will prescribe these to control them.
Treatment for warts
If warts occur frequently, you can see a dermatologist to have them removed. There are several methods for doing so.
- Cryosurgery
- Electrosurgery
- Laser treatment
- Types of special coatings
How to live healthy with WHIM syndrome?
When living with such a rare condition, you have to think more about your health.
- A good diet: A nutritious diet is very important to keep your immune system strong. Include more vegetables, fruits, whole grains, fish, and chicken in your diet.
- Exercise: Exercise helps keep the body strong and boosts immunity. Do something you like, such as a sport, walking, or swimming, every day.
- Protection from infections:
- Avoid crowded places as much as possible.
- Wash your hands often with soap.
- Talk to your doctor about what vaccines you and your family need. Be specific about things like the HPV vaccine, pneumonia vaccine, and annual influenza vaccine.
In addition to your family doctor, you may need the help of various doctors, such as an immunologist, a hematologist, and a dermatologist, to treat you.
Take-Home Message
- WHIM syndrome is a very rare, genetic condition. It is not your fault or your child's fault.
- If your child is getting unusually frequent infections, it is very important to talk to a doctor about it without being careless .
- This disease is not contagious, but it can be inherited from parents to children.
- Although there is no complete cure for this yet, current treatments can control symptoms, reduce complications, and maintain a good quality of life.
- Talk openly with your doctor about any health concerns or concerns you may have.
