Is your child having problems with their eyes, ears, and joints at the same time? This could be Stickler Syndrome!

Sometimes our little ones get sick one after another, right? But some children may suddenly develop several seemingly unrelated problems, such as vision problems , hearing problems, and joint pain. Have you had a similar experience? Then this is about a genetic condition called Stickler Syndrome, which can cause such a condition. Although this may seem a bit complicated, let's talk about it simply.

What is Stickler Syndrome? To be precise...

Simply put, Stickler syndrome is a genetic condition . It is caused by a change in our genes. It mainly affects the connective tissues in our body. This connective tissue is a special type of tissue that connects, supports, and gives shape to other parts of our body, such as organs and tissues. Think of it like using cement and wire to hold the walls and roof of our house together. This connective tissue is also important to our body.

So, in this case of Stickler syndrome, the connective tissues in places like the face, ears, eyes, and joints are most affected. Because of this, some children may have certain facial changes, such as a cleft palate. There may also be problems with vision , hearing, and movement. This is sometimes called Stickler dysplasia.

How common is this condition? Who is most likely to develop it?

Stickler syndrome is estimated to affect one to three out of every 7,500 to 10,000 newborns. However, because the condition is often underdiagnosed, it is difficult to say exactly how many people actually suffer from the condition.

In terms of who gets it, anyone can get Stickler syndrome. However, if someone in the family, that is, a mother, father, or sibling, has the condition, the risk of others developing it is higher. However, sometimes, without any family history, this disease can also occur due to a random change in genes (` genetic mutation`) . That is, it does not have to be something that is inherited.

How does Stickler Syndrome affect the body?

As we've talked about before, this condition affects connective tissue. One of the main functions of connective tissue in our body is to protect and support other tissues and organs. So, when there's a mutation, or defect, in a gene that makes this connective tissue, that gene doesn't get the right instructions on how to make this connective tissue and how it should function.

This is why, for someone with Stickler syndrome,Vision, hearing, and joint movement are affected. The eyes, ears, and joints are particularly affected. People with Stickler syndrome often develop arthritis in childhood . However, with proper treatment, symptoms can be controlled and people with this condition can lead normal, active lives .

What are the symptoms of this? How to recognize it?

The symptoms of Stickler syndrome can vary from person to person . Not everyone will have all the symptoms. That's what makes it so special. For example, one child may have more eye problems, while another may have more joint pain.

There are several main categories of symptoms that can be seen:

Bone and joint problems:

• Initially , the joints may be overly flexible , but over time they may begin to become stiff .
• A curvature of the spine, or scoliosis, may occur.
• Arthritis can develop at a young age. Imagine if a child, not even ten years old, woke up in the morning and complained of pain in their joints, you should be concerned.

Hearing and ear-related problems:

• Hearing loss can occur in varying degrees. Some people may only experience a slight hearing loss, while others may experience complete deafness.

Ocular problems:

• Severe nearsightedness (or myopia) means that only close objects can be seen clearly, while distant objects are blurred.
• Detached retina. This can happen suddenly and requires immediate treatment.
• Cataracts .
• Increased pressure in the eye, which is called glaucoma.

Special features visible on the face:

Often, the facial shape of children with this condition can also be affected in their development.

• Cleft palate : This means that there is a gap in the roof of the mouth.
• Abnormally small and recessed lower jaw (`micrognathia`) : This is sometimes called the `Pierre Robin sequence`. This can cause some children to have difficulty breathing and swallowing.
• The face becomes flat and the nose becomes small.

Other symptoms:

In addition to this, other symptoms may be seen:

• Difficulty breathing (especially in children with micrognathia).
• Feeding difficulties in newborn babies.
• Learning challenges due to vision and hearing impairments.

Important: Not everyone will have all of these symptoms. Don't worry if your child has one or two of these symptoms, but if you see several of them together, it's best to seek medical advice.

Are there different types of Stickler Syndrome?

Yes, there are six main types of Stickler syndrome identified. The severity and nature of the symptoms vary depending on these types.

• Type I: This is the most common type . Mild hearing loss and nearsightedness are the main symptoms.
• Type II: This is more severely affected by hearing loss and nearsightedness.
• Type III: Hearing loss and joint problems are the main symptoms. Vision symptoms are usually absent .
• Types IV, V, and VI: These types are very rare . They can have severe vision and hearing problems. They can also have more complex symptoms, such as enlarged ends of the long bones (spondyloepiphyseal dysplasia) and arthritis.

Doctors determine which type a person belongs to based on symptoms and tests.

What is the cause of this? What is the genetic influence?

The main cause of Stickler syndrome is a genetic mutation . This mutation can occur in any of the six genes that instruct our bodies to produce a special protein called collagen . Collagen is the main thing that gives our connective tissues their flexibility and strength. Think of it like a rubber band, which gives them elasticity and strength.

So, when there is a defect in these genes, the collagen protein is not produced properly. This mainly affects the collagen that makes up our cartilage and the jelly-like substance inside our eyes. Among these genes, genes like `(COL2A1)`, `(COL11A1)`, `(COL11A2)` are the main ones.

If a child inherits one of these mutated genes, they may show symptoms of Stickler syndrome.

How are these genes inherited?

There are two main ways this is inherited:

• Autosomal dominant form:This is the most common type (especially types I, II, and III). What happens here is that even if one parent has the gene mutation, there is a 50% chance that the child will inherit it.
• Autosomal recessive: This is a bit rarer (it can be seen in types IV, V, and VI). Here, both parents must be healthy carriers . That is, they have no symptoms, but they have a mutated gene. If so, there is a 25% chance that the child will inherit the condition.

Sometimes, a new genetic mutation (`de novo mutation`) can occur randomly , without any family history. These things are difficult to predict in advance.

How do doctors diagnose this?

A doctor follows several steps to diagnose Stickler syndrome.

• A detailed family medical history and physical exam: First, you and your child will be asked about your symptoms and whether anyone in your family has had similar conditions. Then, your child will be examined to see if there are any special features on the face, ears, eyes, and joints.
• Vision and hearing tests: These tests are performed by specialist doctors to assess the level of vision and hearing.
• Imaging tests: Sometimes tests such as X-rays may be done to check for any abnormalities in the bones and joints.
• Genetic testing: This is the main test that helps to make a definitive diagnosis. A blood sample or tissue sample is taken and tested for the genetic mutations that cause Stickler syndrome.

Can this be detected before a child is born?

Yes, sometimes prenatal genetic testing can identify any abnormalities or mutations in a baby's genes. However, a definitive diagnosis is usually made after the baby is born, after a complete physical examination and other necessary tests have been performed to confirm the symptoms.

What are the treatments for Stickler Syndrome?

This is a problem that many people have. There is currently no cure for Stickler syndrome. But don't worry. There are many effective treatments to control the symptoms and reduce their impact . Early diagnosis and treatment are the most important things. Especially in cases of a detached retina or joint problems, early treatment can prevent major damage.

Treatment methods vary depending on the symptoms. Here are some of the main treatments:

• Improve eyesightProviding eyeglasses or contact lenses.
• Providing hearing aids to improve hearing.
• Giving medication to reduce joint pain.
• If there is any crookedness or misalignment in the teeth, orthodontic treatment can be performed to correct them.
• Physical therapy ( such as special exercises) to strengthen joints and improve mobility.
• Surgery:
• Reattachment of a detached retina (retinal reattachment surgery).
• Cleft palate repair.
• If breathing is severe, a small tube may be placed in the neck to make breathing easier (possibly a tracheostomy).
• Repair or replace damaged joints.

Through this treatment, children and adults with Stickler syndrome receive great help in leading normal, full, and active lives .

Can this situation be prevented?

Stickler syndrome is a genetic condition, so it cannot be prevented . However, if someone in your family has the condition and you are planning to have a child, genetic counseling and genetic testing can help you understand the risk of your child inheriting the condition.

What can you expect when living with Stickler Syndrome?

Although there is no cure for this condition, it does not affect a person's life expectancy . That is, people with this condition live a normal life span like everyone else. With regular medical monitoring, necessary treatment, and support, many people live very active and fulfilling lives.

The most important thing is to diagnose the disease in infancy or early childhood . Then, symptoms can be managed quickly and complications that may arise in the future can be prevented.

Sometimes symptoms can recur even after treatment. For example, even if you have surgery to remove a detached retina, the condition can recur. Therefore, it is very important to attend regular medical check-ups and pay attention to your symptoms .

Is there any impact on daily activities?

This varies from person to person, depending on the nature of the symptoms. Some people may not have much of an impact, while others may have to live with some limitations. In particular, doctors advise avoiding contact sports , such as rugby and football, as the risk of retinal detachment is higher in such sports.

When should you see a doctor?

If you or your child have symptoms that you think could be related to Stickler syndrome and are affecting your daily activities to the point where you can't function, be sure to see a doctor.

• If you have severe joint pain .
• If your vision suddenly changes (for example, blurred vision, seeing lights flashing before your eyes, seeing black dots or nets floating before your eyes, or feeling like a shadow in part of your vision - these may be signs of a detached retina).
• If you have difficulty swallowing food or drink.
• If the area where you had surgery is bleeding, swollen, or has a yellow discharge (this could mean an infection).

Extremely important: If you or your child have difficulty breathing , it is an emergency. Go to the nearest hospital immediately, or call 1990.

What are the important questions to ask the doctor?

Once you know that you or your child has Stickler syndrome, you can ask the doctor questions like these:

• How serious is this condition called Stickler Syndrome?
• What is the reason for this?
• How will this affect my child's daily life?
• What complications should I be especially concerned about? What are their symptoms?

In addition to these questions, talk to your doctor about anything you're thinking, any fears, or doubts you have.

Finally, the most important points (Take-Home Message)

Stickler syndrome can be a bit scary to hear. But keep these things in mind:

• This is a genetic condition , not something that is due to your negligence.
• Because it mainly affects connective tissue , it can cause changes in the eyes, ears, joints, and face.
• Symptoms can vary greatly from person to person .
• Although there is no complete cure, there are many treatments available to help control symptoms and live a better life .
• Early diagnosis and initiation of treatment are the best ways to achieve successful outcomes.
• If someone in your family has this condition, it is important to seek genetic counseling .

By not panicking and following proper medical advice, a person with Stickler syndrome can set the stage for a good life like everyone else. If you have any further questions, don't hesitate to talk to a doctor.
