What is Apert Syndrome? Does your baby have these symptoms? Let's talk!

Have you noticed any unusual features in your newborn baby's head shape, face, or limbs? Sometimes, as parents, we get a little worried when we see these things, don't we? It's very common. Today, we're going to talk about Apert syndrome , a rare condition that can affect babies born with some of these physical changes. Don't worry, let's explain everything in simple terms.

What exactly is Apert Syndrome?

Simply put, Apert syndrome is a rare condition in which the joints between the bones of your baby's skull, or what we call 'sutures', fuse together before they can develop . Doctors call this craniosynostosis . When the sutures close too quickly, the skull doesn't have enough room to expand as the baby's brain grows. This can cause changes not only to the shape of the skull, but also to things like the bones of the face, fingers, and toes.

Think of it like a small tree growing out of a hole in the ground, and it can't grow freely. This is a genetic condition , meaning it's caused by a change in genes. It can sometimes be inherited as an 'autosomal dominant' trait . This means that if one parent has the genetic change, there's a 50% chance that their child will also have the condition.

Who is affected by Apert Syndrome?

Apert syndrome is a very rare condition . It is most often caused by a genetic mutation that occurs early in pregnancy. This mutation can be inherited from the parents or can occur de novo. The important thing is to understand that this is not something the mother did during pregnancy, and it is not something that happens to her. So don't blame yourself.

How common is this?

This is actually very rare. According to statistics, only about one in every 65,000 babies born have Apert syndrome. So you can see how rare this condition is.

What are the symptoms of a baby with Apert Syndrome?

Because the sutures in the baby's skull close prematurely, a condition called craniosynostosis, the baby may have certain distinctive features. These features may vary slightly from one baby to another. The main features that can be seen are:

• Skull:
• The baby's head may appear taller than normal, with a pointed tip (this is called acrocephaly) .
• The back of the head may be flat.
• The forehead can appear high or wide.
• The 'soft spot' or 'follicle' on the baby's head may be delayed in closing.
• Eyes:
• The eyes may be located further apart on the face than normal.
• The eyes may appear bulging or slanting downward.
• Face:
• The nose can be flat or beak-like.
• There may be a cleft palate .
• The face may appear asymmetrical on both sides.
• Hands and feet:
• The fingers may be short and the big toe may be wide.
• The fingers or toes may be fused together or connected by skin (this is called syndactyly) , like a swimming web.

Remember, not every baby will have all of these symptoms. A doctor is the one who can accurately identify these symptoms and make a diagnosis.

How else does Apert Syndrome affect the baby's body?

This condition not only causes changes in the baby's appearance, but it can also affect other organs in the body.

• Brain: As the skull closes quickly, pressure can build up on the brain. This can affect the baby's learning and thinking skills ( cognitive development ). Mild to moderate intellectual disabilities may also occur.
• Ears: Often, the bones on either side of a baby's head are the first to close. This can affect the way the ears develop, leading to frequent ear infections or hearing loss.
• Eyes: Vision problems can occur due to protruding, slanted, or far-set eyes.
• Lungs: Depending on the severity of the condition, the shape of the nose can cause breathing difficulties or sleep apnea ( suffocation due to obstruction of the airway during sleep).
• Skin: Your baby's skin may produce more oil, which can lead to severe acne. You may also notice excessive sweating ( hyperhidrosis ) and hair loss in some areas (for example, under the eyebrows).
• Teeth: When a baby starts teething, there is not enough space in the mouth and the teeth can become overcrowded. This can cause dental problems. Some teeth may be missing and there may be irregularities in the enamel of the teeth.

What causes Apert Syndrome?

The main reason for this is a mutation in the gene called FGFR2 (Fibroblast growth factor receptor-2) . This gene is largely responsible for the development of the skeletal system in our body. When this gene is mutated, these receptors do not communicate properly with signals called 'fibroblast growth factors'. As a result, the joints (sutures) between the bones close quickly during the embryonic stage. Even though these sutures close quickly, the baby's brain continues to grow. Then the bones of the skull, especially the bones of the forehead and the sides of the head, form abnormally. The irregular formation of these bones is what causes various deformities in the body.

How is Apert Syndrome diagnosed?

Most of the time, this condition is diagnosed after the baby is born. However, it can sometimes be diagnosed early during pregnancy, by looking at the baby's bone development with a prenatal 2D or 3D ultrasound or an MRI scan .

After the baby is born, the doctor will perform a complete physical examination to check for any abnormalities in the baby's body. Then, imaging tests , such as a CT scan or MRI , will be performed to confirm these congenital defects.

The doctor will also recommend genetic testing . This will check for a mutation in the FGFR2 gene mentioned earlier. This will further confirm the diagnosis. All the normal newborn screenings will be done for this baby. In particular, since this condition can cause hearing loss, special attention will be paid to a hearing test .

How is Apert Syndrome treated?

Treatment options depend on the severity of your baby's condition. In most cases, surgery is the main treatment to reduce symptoms.

• If there are signs of problems affecting the skull or brain (craniosynostosis or hydrocephalus - accumulation of fluid on the brain): Between two and four months after birth, surgery may be performed to remove the fluid that has accumulated in the brain and place a small tube ( shunt ) to reduce pressure.
• Reconstructive or corrective surgery:
• Surgery to correct the eyes.
• Jaw bone reconstruction surgery ( osteotomy ).
• Chin plastic surgery ( genioplasty ).
• Plastic surgery of the nose ( rhinoplasty ).
• Surgery to separate fingers and toes that are fused together.
• Surgery to correct the shape of the skull ( cranioplasty ).

Are there other treatments to reduce side effects?

Yes, absolutely. Your baby can reach his or her full potential if you start the necessary treatment as soon as possible, as recommended by your doctor. Treatments like these include:

• Hearing aids if you have hearing loss.
• If you have difficulty breathing due to airway obstruction, you may need a breathing machine or other treatment .
• Scheduled appointments with various therapists. For example, physical therapy , occupational therapy, and speech therapy .
• Taking special care of the baby's mouth and teeth.
• Regular vision assessment due to eye problems.

Can Apert Syndrome be completely cured?

Unfortunately, there is currently no cure for Apert syndrome. However, surgery can significantly reduce symptoms and help the baby live a normal life.

Is there anything I can do to reduce my child's risk of developing Apert Syndrome?

Because Apert syndrome is a genetic condition, there is really nothing parents can do to prevent it from occurring during pregnancy. However, if you are planning to have a child, you can see a doctor for genetic counseling to see if you are at risk of passing on the condition to your child. Genetic counseling can help you understand the likelihood of having a child with the condition in the future and provide support to new parents.

What should I expect if my baby has Apert Syndrome?

Apert syndrome is a lifelong condition and there is no cure. The baby often needs surgery to relieve pressure on the brain at birth, followed by several reconstructive surgeries. Close follow-up with a variety of specialists is essential.

However, with surgery and ongoing treatment, babies born with Apert syndrome can live a normal life. They should stay in regular contact with their doctor to discuss any problems they may have as they grow. As your baby grows, they should have their vision, teeth, and hearing checked regularly. Sometimes, more surgery may be needed to treat ongoing symptoms.

When should I see my doctor?

If you notice any of these symptoms in your baby, see a doctor immediately:

• If you have difficulty breathing .
• If you have frequent ear infections or have difficulty listening to simple commands.
• If developmental milestones are not reached for the age.
• If the surgical site is infected (red, swollen, pus-like).

What questions should I ask my doctor?

Discuss any questions or concerns you have with your doctor. For example, you might ask questions like:

• What treatment do you recommend for my baby's diagnosis?
• What are the risks of surgery?
• Does the shape of my baby's head affect his learning?
• If I have another child, is there a chance that that child will also develop Apert syndrome?

What other conditions are similar to Apert Syndrome?

Some of the symptoms of Apert syndrome may be similar to other conditions caused by the rapid fusion of the skull bones during fetal development (craniosynostosis). Some of these conditions include:

• Carpenter syndrome: Similar to Apert syndrome, this is a condition in which the baby's skull fuses together prematurely, causing skull abnormalities. It can also cause syndactyly (fingers and toes that are joined together). The difference is that Carpenter syndrome occurs when both parents pass on the gene to the child (autosomal recessive).
• Crouzon syndrome: This also causes facial abnormalities due to the baby's skull fusing together too quickly.
• Pfeiffer syndrome: In this condition, along with skull and facial abnormalities, the big toes and big toes may be wider than the other toes and may be curved away from the other toes.
• Saethre-Chotzen syndrome: This is a condition in which the skull bones fuse together prematurely, resulting in uneven, asymmetrical facial features.

What is the difference between Apert Syndrome and Crouzon Syndrome?

Apert syndrome and Crouzon syndrome share some of the same features. Both are caused by premature closure of the skull joints during fetal development. In both conditions, the skull can be abnormally shaped, and the face may appear sunken in (midface hypoplasia). The main difference, however, is that in Apert syndrome, other parts of the body are affected in addition to the skull, especially syndactyly, which is a condition in which the fingers and toes are joined together. In Crouzon syndrome, the shape of the skull is mainly affected.

Finally, things to remember (Take-Home Message)

Apert syndrome is a genetic condition that can cause changes in a baby's appearance and some of their body functions. Although there is no cure, surgery and various treatments can help control symptoms and help the baby live as normal and full a life as possible.

If someone in your family has Apert syndrome and you are expecting a child, it is very important to seek genetic counseling . This will provide you with the information and guidance you need.

The most important thing is to know that you are not alone. You can get support from doctors, counselors, and parents of children with similar conditions. Don't be afraid to talk to your doctor about everything that's on your mind.
