Have you ever noticed that one of your child's legs is a little longer than the other? Or does one side of their face seem bigger than the other? Sometimes these things can be normal. However, some children may have a rare condition where parts of their body are abnormally large. Today we are talking about the PROS of such a condition. Don't be afraid to see this, the most important thing is to understand it.
Simply put, what are these PROS?
PROS may sound a bit complicated. Its full name is
PIK3CA-Related Overgrowth Spectrum . Simply put, PROS is not a single disease. It is a group of rare, related conditions that cause parts of the body to grow excessively large or abnormally. Just like there are many colors in the rainbow, there are many different conditions under the PROS umbrella. The one thing all of these conditions have in common is that they are caused by a mutation in a gene called `PIK3CA` in the body. This
is not someone's fault . This is a random genetic change that occurs after the baby is conceived in the womb.
The important thing is that everyone with PROS is different. One child's symptoms may not be the same as another's. So your child's condition is unique.
There are several common characteristics that are commonly seen in PROS situations. Let's take a look at what they are.
| Symptom | A simple explanation |
|---|
| Enlargement of body parts | Abnormal enlargement of one or more body parts, such as an arm, leg, or finger. |
| Brain changes | Some children have an enlarged brain or one half of the brain. |
| Fatty lumps | The formation of fatty tumors in various parts of the body, especially in areas such as the abdomen. |
| Changes in bones | Conditions such as bone deformities and scoliosis. |
| Changes in fingers | Abnormally long, enlarged, or fused fingers or toes. |
| Skin spots | Dark spots on the skin or rough patches in some areas. |
| Blood vessel problems | Abnormal growth of blood vessels (vascular malformations), which can increase the risk of blood clots. |
| Other features | Low muscle tone, seizures, and delays in learning or intellectual development. |
Different types of PROS and their characteristics
Doctors classify PROS conditions based on the symptoms the child exhibits. Let's look at some of the main types and their characteristics.
CLOVES syndrome
Children with this condition may have blood vessel changes that appear as dark spots on the skin and abnormal fingers at birth.
Other symptoms of CLOVES syndrome
| Fatty nuts | Formation of tumors made of fat in the body. |
| Skin changes | Skin spots or skin growths. |
| Bone changes | Conditions such as scoliosis. |
| Changes in limbs | Enlarged fingers, asymmetrical growth of limbs. |
| Kidney problems | One kidney is missing or small. |
This condition affects the brain and many other parts of the body. Many children with MCAP are born with an unusually large head. The head can grow rapidly during the first year of life.
Symptoms of MCAP syndrome
| Brain enlargement | Enlargement of the entire brain or one half of the brain. |
| Facial changes | Full cheeks and lips. |
| Skin discoloration | Changes in the appearance of the skin (especially on the face) due to changes in the small blood vessels (capillaries). |
| Muscle weakness | Decreased stiffness in the body's muscles. |
| Other features | Seizures, intellectual disabilities, speech delay, clubbing or having extra fingers, excessive joint flexion, and heart changes. |
Hemimegalencephaly
This condition mainly affects one side of the brain. It can occur alone or with other syndromes.
Main symptoms: changes in one side of the brain, large and disproportionate head, seizures , partial paralysis on one side of the body, and developmental delays.
Facial Infiltrating Lipomatosis
The main characteristic of this is that one side of the face is larger than the other.
Other symptoms: non-cancerous tumors that form in nerve tissue (especially on the tongue or lips), enlarged tongue, enlarged facial bones , and early eruption of permanent teeth.
How to manage this situation?
PROS can get worse over time. Depending on the parts of the body affected, your child may have difficulty walking and performing daily activities. But
the good news is that there are treatments that can help manage the condition and make your child's life easier. This is not something you have to deal with alone. It's important to work with your child's
doctor and other specialists (for example, an orthopedic specialist, a neurologist) to discuss and understand what treatment options are best for your child. Sometimes, symptoms can be controlled through things like surgery, medication, or physiotherapy.
Take-Home Message
- PROS is not a single disease, but a collection of several rare conditions in which parts of the body grow abnormally.
- This condition occurs due to a genetic change, not through any fault of the parents.
- Every child with PROS is different. Symptoms can vary greatly from one child to another.
- If you notice any asymmetry, abnormal growth, or other suspicious features on any part of your child's body, talk to your doctor immediately .
- Although this condition cannot be completely cured, there are treatments that can help control the symptoms and improve the child's quality of life .
