Moms and dads, are you always worried about your little one's health? Sometimes, even the smallest illnesses that come with your baby can be scary. Today, we're going to talk about a condition that's a little rare, but it's very important to know about. This is called CHARGE Syndrome . This may sound new to you, but don't worry. Let's talk about it simply and in a way that you can understand.
What is CHARGE Syndrome? Simply put...
CHARGE syndrome is a rare genetic condition . It can affect several parts of your child's body. Think about it, the eyes, nervous system, heart, nasal passages, genitals, and ears are the main areas affected. Children with this condition may have distinctive facial features and a combination of symptoms. Doctors diagnose the condition based on all of these factors.
The important thing is that not every child with CHARGE syndrome is the same. The symptoms and their nature can vary from one child to another. Some abnormalities can begin in the womb, and the condition can affect the child in different ways, for many years.
Who can develop CHARGE syndrome?
This is a genetic condition that can affect anyone. Most often, it is caused by a new genetic mutation . This means that no one in the family has had it before. Sometimes, the child can inherit this mutated gene from one of the parents at the time of conception. This genetic mutation occurs randomly. Therefore, there is nothing that parents can do to prevent this condition, either before or during pregnancy.
How common is this situation?
CHARGE syndrome is a very rare condition . Worldwide, it is estimated that only one in 8,500 to 10,000 newborns are affected by the condition.
How does CHARGE syndrome affect my child's body?
When the gene that causes this condition is mutated, our cells don't get the instructions they need to grow and function properly. That's why it affects many parts of the body. Symptoms can sometimes be mild, but sometimes they can be very severe and even life-threatening . This is especially true if the baby's heart and internal organs haven't developed properly while it's growing in the womb.
Your doctor will closely monitor your baby's development even before birth. This is to prepare for your baby's arrival and to plan for immediate treatment to prevent life-threatening complications. This is especially important if symptoms affect things like the heart, breathing, or eating.
What are the symptoms of CHARGE syndrome?
The letters in the name CHARGE can help you remember some of the main symptoms of this condition.
- C - Coloboma and cranial nerve abnormalities:
- The loss of some tissue in the eye. This may look like a small cut in the iris of the eye.
- Problems with balance and coordination.
- Paralysis of one side of the face.
- Decreased sense of smell.
- H - Heart defects:
- Heart disease that is present at birth (congenital). For example, conditions such as tetralogy of Fallot , ventricular septal defect , atrioventricular canal defect, and/or aortic arch abnormalities .
- A - Atresia of the choanae:
- Narrowing or complete blockage of the nasal passages can cause breathing difficulties and sleep apnea.
- R - Restriction of growth and development:
- The child needs additional time to reach age-appropriate height and weight goals.
- It also takes extra time to reach age-appropriate developmental milestones.
- G - Genital abnormalities:
- In boys, the penis is small (micropenis) and/or the testicles are not descended (cryptorchidism) .
- E - Ear abnormalities:
- Abnormalities such as protruding ears and missing earlobes.
- Hearing impairment, possibly even deafness.
Although many symptoms are visible at birth, sometimes the condition can be diagnosed later in life, when symptoms appear later.
What are the other additional symptoms?
In addition to these main symptoms, other symptoms may include:
- Difficulty swallowing food and drink.
- Problems of intellectual development.
- Cleft lip or cleft palate.
- Muscle weakness (Hypotonia).
- Kidney abnormalities: excess fluid in the kidneys (hydronephrosis) , reflux of urine into the kidneys, or a kidney that is small or missing.
- Malfunction of the passage from the esophagus to the stomach (esophageal atresia) .
- Anxiety or anxious behaviors.
- Scoliosis .
Special features seen on the face
Children with CHARGE syndrome may also have certain facial features:
- A square-shaped face.
- A broad forehead.
- Curled eyebrows.
- Big eyes.
- Drooping eyelid.
- A small mouth and chin.
- Asymmetrical face.
What causes CHARGE syndrome?
This is most likely caused by a genetic mutation in a gene called CHD7 . This CHD7 gene instructs our cells to make a protein that packages our DNA into chromosomes, like wrapping a gift. This packaged DNA can be remodeled, meaning it can be packed tightly or loosely according to the needs of each chromosome.
In a person with CHARGE syndrome, the `CHD7` gene does not produce proteins properly. Then the DNA molecules cannot be packaged according to the instructions. That is why these symptoms appear.
Very rarely, some people with CHARGE syndrome do not have a mutation in the `CHD7` gene. Or they may have a mutation in another gene in their DNA. These rare causes are still being researched. Genetic counseling is very important in such cases.
Can CHARGE syndrome be inherited?
Yes, this is a condition that can be inherited. If a person inherits one copy of the mutated CHD7 gene at conception, the symptoms can occur. This is called autosomal dominant transmission. However, most of the time, these genetic changes occur as de novo mutations. This means that no one in the family has had the condition before. A parent with two children with CHARGE syndrome, or a person with CHARGE syndrome, has a 50% chance of having a child with the condition.
How is CHARGE syndrome diagnosed?
Your child's doctor will first physically examine your child to check for the main symptoms of this condition. To confirm the diagnosis, the doctor will perform a genetic test . This involves taking a small blood sample and looking for changes in the CHD7 gene.
To make sure your child's symptoms are not life-threatening, you may need to have additional blood, urine, or imaging tests. These are done to check the health of your child's internal organs. These tests will vary from child to child, depending on their symptoms. Talk to your doctor about any additional tests that may be needed to make sure your child is healthy.
How is CHARGE syndrome treated?
Treatment for CHARGE syndrome varies from child to child. The main focus is on relieving the child's symptoms. Treatment options may include:
- Surgery for conditions such as cleft lip or palate, heart disease, or choanal atresia.
- Participating in occupational therapy, physical therapy, or speech therapy to teach your child proper eating habits and overcome speech and language challenges.
- Inserting a feeding tube to help the child eat until they learn to swallow.
- Using a ventilator or CPAP machine to help with breathing difficulties or sleep apnea.
- Use of hearing aids or cochlear implants for hearing impairment.
- Referral for special education to enhance intellectual development.
- Giving medications for specific symptoms.
A care coordinator is the key person to successfully manage this condition and provide emotional support. Ask your healthcare provider for more information.
How do I care for my child with CHARGE syndrome?
A child with CHARGE syndrome may need extra time to grow and develop. They may be a little behind on age-appropriate milestones, such as sitting up without support and talking. During the first few years of life, keep a close eye on your child's developmental milestones. Tell your doctor if your child is missing any milestones. Your doctor will monitor your child's development at clinics and monitor their progress over the years. Keep regular checkups and tests to make sure your child is healthy as they grow and is not at risk for any side effects of the diagnosis.
Can CHARGE syndrome be prevented?
No, CHARGE syndrome is a genetic condition and cannot be prevented . The gene mutation that causes it often occurs randomly, without anyone in the family having had the condition before. Therefore, it is difficult to detect it in advance.
What can you expect from someone with CHARGE syndrome?
When a baby is first diagnosed with this condition, the doctor will do tests to see if the baby's heart and internal organs are working properly and if there are any life-threatening symptoms. If there are any developmental abnormalities, especially those affecting the heart, surgery may be needed to correct them. Many newborns need help swallowing. Therefore, the doctor may place a feeding tube in the baby's stomach to provide the nutrition they need to survive until they can swallow on their own. There are many additional treatments and supports available to meet your baby's health needs.
There is no complete cure for CHARGE syndrome.
What is the life expectancy of someone with CHARGE syndrome?
The life expectancy of a newborn with CHARGE syndrome varies depending on the severity of their symptoms. Babies with severe symptoms have a higher mortality rate within the first five years of life. However, children with mild symptoms can live a normal life with lifelong supportive care.
If your child is diagnosed with CHARGE syndrome, talk to your doctor about their symptoms and life expectancy to help them live a happy, healthy life.
When should I see my child's doctor?
See a doctor if your child has any of the following:
- If there is an infection at the surgical site.
- If age-appropriate developmental milestones are not reached.
- If you can't eat or drink.
- If you have any hearing or vision problems.
- If you have difficulty swallowing.
If your child has difficulty breathing, changes in body color, severe difficulty eating, or an abnormal heart rate, go to the hospital immediately.
What questions should I ask my doctor?
- How severe are my child's symptoms?
- What is my child's life expectancy?
- Does my child need surgery?
- Are there any side effects to the medications you are prescribed?
It's normal to feel overwhelmed when you learn that your newborn has a rare genetic condition. Some parents and caregivers find genetic counseling a great way to learn more about their child's diagnosis and how to help their child live a better life. Keep a record of your child's symptoms and whether they are meeting developmental milestones for their age at the clinic. Contact your doctor if you have any questions or concerns about your child's health.
