As a mother, how sad and scared you must feel if your little one is born with a strange appearance, lifeless, or limp, or if the doctors say that there is a problem with the development of the eyes or brain? Sometimes the cause of this can be a very rare, but very serious, genetic condition that is present at birth. Today we are going to talk about one such disease, Walker-Warburg Syndrome.
What is Walker-Warburg Syndrome?
Simply put, Walker-Warburg Syndrome is a genetic condition that affects the muscles in your child's body, especially the brain and eyes. It belongs to a group of diseases called congenital muscular dystrophies, which begin at birth or in infancy and gradually weaken the muscles over time. In fact, this condition causes life-threatening symptoms in children and, unfortunately, shortens their lifespan. This may sound scary to you, but it's important to know what it is.
What is dystroglycanopathy? Is there a connection?
You may have heard Walker-Warburg Syndrome referred to as Dystroglycanopathy . Don't worry, I'll explain it.
Walker-Warburg syndrome is a type of congenital muscular dystrophy. Muscular dystrophy is a group of diseases that affect the muscles of a child's body. Several types of these muscular dystrophies are classified as dystroglycanopathies. That is, muscular dystrophies caused by defects in the genes that produce the protein dystroglycan are called this name. Walker-Warburg syndrome is considered the most severe, or serious, type of this dystroglycanopathies group.
How common is this condition? Who can get it?
Walker-Warburg Syndrome is a very rare disease. Worldwide, it is estimated that about one in 60,500 newborns suffer from this disease. Since it is the result of a genetic mutation, anyone can develop this condition. This means that race, religion, etc. are not relevant.
Can my child inherit this disease?
Yes, your child can inherit Walker-Warburg Syndrome from their parents. This happens when both parents are carriers of one of the mutated genes that causes Walker-Warburg Syndrome, meaning they both have one copy of the defective gene, and the child will only get the disease if both parents pass on the gene to the child at the time of conception. This pattern of inheritance is called autosomal recessive inheritance.
Imagine, if your child inherits only one copy of this mutated gene from one parent, the child will not show symptoms, but the child will be a carrier of the disease. This means that the child's children in the future may have some risk of developing this disease, if the other parent is also a carrier.
How does Walker-Warburg Syndrome affect my child's body?
This disease mainly affects the muscles of your baby's body. You may notice changes in your baby's muscles as soon as he or she is born. The baby's body may be very floppy, like a lifeless doll , because the muscles have very little muscle tone. In addition to the muscles, this condition also affects the way your baby's brain and eyes develop and function. Your baby may have vision problems, developmental delays, and intellectual development problems. Doctors try to control these symptoms with treatment and prevent the baby from having a shortened life expectancy.
What are the symptoms of Walker-Warburg Syndrome?
Walker-Warburg Syndrome causes symptoms that affect your child's muscles, brain, and eyes. The severity of these symptoms can vary. They are usually seen at birth or in early infancy. Some symptoms can be life-threatening.
Muscle-related symptoms
The symptoms of Walker-Warburg syndrome affect the muscles used for movement in a child.
- When a baby is born, they may appear "floppy" like a lifeless doll due to low muscle tone (hypotonia) . This makes it difficult for the baby to lift their head, arms, and legs.
- This condition causes the child's muscles to gradually weaken , meaning that symptoms worsen over time.
- Because the baby's muscles are not functioning properly, it can be difficult to drink milk during early infancy . They may not be able to suck or swallow properly.
Brain-related symptoms
Walker-Warburg Syndrome affects the way your baby's brain develops. Brain-related symptoms may include:
- Lissencephaly (smooth brain) is a condition where the brain appears to have bumps on its surface, without the normal folds or grooves. In other words, the surface of the brain appears to be smooth.
- Accumulation of fluid in the brain (Hydrocephalus) can cause the head to become enlarged.
- Developmental abnormalities of the brainstem and cerebellum or a condition called a cerebellar cyst (Dandy-Walker malformation) .
- Seizures , that is, seizure-like conditions.
These conditions, which affect your child's brain, can cause delayed development and challenges with intellectual abilities .
Eye-related symptoms
Walker-Warburg Syndrome can affect the development of your child's eyes and can cause symptoms such as:
- Small eyes (Microphthalmia) or large eyes (Buphthalmos) .
- Cloudiness of the eyes, which means the lens of the eye has turned white (Cataracts) .
- A delay in the transmission of messages through the optic nerves that send messages from the eyes to the brain.
- Difficulty seeing clearly (Vision impairment) .
What is the reason for this? Why is this happening?
Walker-Warburg Syndrome is caused by a genetic mutation . More than a dozen genes have been identified that cause the condition, and there may be more that have not been identified. Some of the main genetic mutations that cause the disease in more than half of all people with Walker-Warburg Syndrome are:
- `POMT1`
- `POMT2`
- `CRPPA` (formerly known as `ISPD`)
- `FKTN`
- `FKRP`
- `LARGE1`
- `POMGNT1`
- `ISPD`
- `GTDC2`
- `DAG1`
These genes interfere with the process of adding sugar molecules to a protein called alpha-dystroglycan , a process called glycosylation . When this glycosylation process doesn’t happen properly, the baby’s muscle fibers can’t maintain their structure in the body. These proteins also affect the way nerve cells in the brain move during the embryonic stage, which is what causes the brain condition called lissencephaly mentioned earlier.
Simply put, the muscles of a child with Walker-Warburg Syndrome constantly tighten and loosen. Over time, these muscle fibers become damaged and weak to the point where they can no longer function.
In addition, Walker-Warburg Syndrome disrupts the way neurons travel in a child's brain. Normally, neurons should stop when they reach their destination. However, the affected neurons also travel into the fluid surrounding the child's brain. This has a major impact on brain development.
How is Walker-Warburg Syndrome diagnosed?
Your doctor may begin testing for Walker-Warburg Syndrome in late pregnancy, and the diagnosis is confirmed after the baby is born.
- An ultrasound scan during pregnancy can detect symptoms, especially those affecting the baby's brain.
- After the baby is born, imaging tests such as CT scans and MRIs can provide a clear picture of the baby's brain and assess the condition.
There are several tests to confirm the diagnosis of Walker-Warburg Syndrome:
- A muscle tissue biopsy is a test to see if the child's muscle fibers are healthy. This involves taking a small piece of muscle and examining it.
- A blood test to check the level of Creatine Kinase (CK) in the blood. CK is an enzyme that is released into the blood when muscle tissue breaks down. High levels of CK indicate muscle damage.
- An eye exam to check for signs of Walker-Warburg Syndrome in the child's eyes.
- A genetic blood test to identify the mutated gene causing the symptoms.
What are the treatments for this?
Unfortunately, there is no cure for Walker-Warburg Syndrome. Therefore, treatment is primarily aimed at relieving symptoms. Treatment options may vary for each child diagnosed with the condition, depending on the child's condition. Treatment options may include:
- Surgery to remove excess fluid from the brain (hydrocephalus).
- Giving medications to prevent seizures.
- Physical therapy to improve muscle strength.
- If you have difficulty eating, inserting a feeding tube can help.
The goal of treatment for Walker-Warburg Syndrome is to prevent life-threatening symptoms and help increase the child's life expectancy.
Is there a way to prevent Walker-Warburg Syndrome?
Walker-Warburg Syndrome is a genetic condition, so there is no way to prevent it. If you are planning to become pregnant and want to know your risk of having a child with a genetic condition, it is a good idea to talk to your doctor about genetic testing or genetic counseling .
If my child has this disease, what should I expect?
Walker-Warburg Syndrome is a progressive disease. This means that the symptoms may be mild at first, but they get worse over time. This may sound very sad, but babies with this condition usually have a short life expectancy , often only until early childhood. Your child's doctor will provide treatment to prevent life-threatening symptoms and prolong your child's life. Remember, there is no cure for this disease.
With your child's diagnosis, it's important to take care of yourself. It can be helpful for you and your family to talk to a genetic counselor to help you understand and cope with your child's diagnosis and treatment options. A mental health professional can also help you prepare for and cope with the sudden loss that comes with your child's diagnosis. Bereavement and support groups can be a great source of comfort for families during these difficult times.
When should I take my child to the doctor?
If your child shows symptoms of Walker-Warburg Syndrome, especially not being able to eat , call your child's doctor right away. Also, let your doctor know if your child's symptoms suddenly return or get worse , even if treatment is successful to relieve symptoms.
Your child is at risk of having seizures . If you see your child temporarily losing consciousness, twitching or moving uncontrollably, or appearing confused, frightened, or restless, go to the hospital emergency room immediately.
What questions should I ask my child's doctor?
You may have many questions during this difficult time. Try asking your child's doctor these questions:
- Does my child need surgery?
- What are the side effects of the treatments?
- What do I do if my child has a seizure?
- How often should I bring my child for wellness checkups?
Finding out that your newborn has a genetic condition that will prevent them from living a full life can be a very traumatic experience. With this challenging diagnosis, your doctor will provide treatment to prevent life-threatening symptoms and extend your child's life expectancy. Your child's diagnosis can be very emotional for you and your family, so make sure you get the support you need. Many people find genetic counseling helpful to learn more about how to care for their child. A mental health professional can help you manage stress, prepare for and cope with an unexpected loss. If you need help, talk to your doctor and be supportive.
