Have you ever seen or heard of a person whose body parts – say, an arm or a leg – grow much larger and disproportionately larger than the rest? Or the skin in some places becomes thicker and looks like strange lumps? This is a very rare condition. Today we are going to talk about a condition that is a little strange, but it is very important for everyone to be aware of. It is called Proteus Syndrome.
What is Proteus Syndrome?
Simply put, Proteus Syndrome is a very rare genetic condition . It causes your body's bones, skin, internal organs, or tissues to grow excessively . Importantly, this growth is usually asymmetrical . This means that the right and left sides of the body are affected differently. One side may be larger, while the other side may be normal.
This is called "Proteus", there was an ancient Greek god named "Proteus", who could change into any shape. This disease also changes the shape of the body, so it got its name.
A newborn baby usually does not show any signs of this condition. This abnormal development begins between 6 and 18 months of age . It then progresses rapidly during the first 10 years of life and can become more severe as they grow older. In addition to changes in physical appearance, some people may develop neurological issues. People with Proteus syndrome also have an increased risk of blood clots and noncancerous tumors .
Who can get this? How common is it?
Proteus syndrome can affect anyone, but some studies have shown that it is slightly more common in men than in women.
This is a very rare condition . It affects less than one in a million people worldwide. Because it is so rare, and because there are other conditions that also show asymmetric growth, it is difficult to diagnose it accurately. Therefore, it is difficult to say how many people actually have it. Doctors believe that some people are undiagnosed, and others have been misdiagnosed. However, it is believed that fewer than a hundred people worldwide have the condition.
What are the symptoms? How do you recognize it?
The first signs of Proteus syndrome usually appear between the ages of 6 and 18 months . This is when the asymmetric growth pattern mentioned earlier begins. The pattern of this growth and its severity can vary greatly from person to person. It can affect any part of the body, including the bones, skin, organs, and tissues. The condition progresses rapidly during the first ten years of life.
### Changes in bones:
The bones in your arms, legs, skull, and spine may grow irregularly.
- Arms and legs can grow to significantly different lengths . Imagine one arm being longer than the other, or the length of your legs being different.
- Severe curvature of the spine (scoliosis) can occur.
- Over time, this abnormal growth may cause the joints to become unable to function properly.
### Skin changes:
Proteus syndrome can cause abnormal growths on the skin.
- In some places, the skin thickens and rises, forming a wrinkled bump that resembles the surface of the brain. This is called a cerebriform connective tissue nevus .
- These are usually seen on the soles of the feet , but can sometimes develop on the hands.
This type of skin lump is so unique that it is not seen in any other medical condition.
### Blood vessels and adipose tissue:
- There may be abnormal growth of your blood vessels, namely capillaries and veins.
- Adipose tissue can develop excessively, causing excess fat to accumulate in areas such as the stomach, arms, and legs.
- Often, non-cancerous, fatty tumors (lipomas) can develop.
### Nervous system problems:
Some people with Proteus syndrome also experience problems with the nervous system.
- Intellectual disabilities.
- Epileptic conditions `(Seizures)`.
- Vision loss.
### Changes in facial appearance:
Proteus syndrome can cause some distinctive facial features.
- An elongated face.
- The outer corners of the eyes appear to be drooping.
- A flat nose bridge and wide nostrils.
- It's like having your mouth open.
What are the dangerous complications that can occur due to this?
The most life-threatening complication of Proteus syndrome is deep vein thrombosis (DVT), a blood clot in the deep veins . DVT often affects the deep veins of the legs or arms, causing pain and swelling.
If this `DVT` travels through the bloodstream to the lungs, it can cause a dangerous condition called `Pulmonary Embolism`. Pulmonary embolism is the most common cause of death in people with Proteus syndrome.
How does Proteus Syndrome develop? Is it genetic?
This is caused by a change (mutation) in a gene called `AKT1` . The `AKT1` gene helps control cell growth and division. When this gene is mutated, a cell loses its ability to control its growth. This causes the cell to grow and divide abnormally. This is what causes the excessive growth seen in Proteus syndrome.
The important thing is that Proteus syndrome is not a hereditary disease. This gene mutation occurs after fertilization of the embryo, which is called a somatic mutation . This mutation occurs by chance in a single cell of the developing embryo early in pregnancy. As this mutated cell grows and divides, some cells have this mutation and some do not. This is called a mosaic gene alteration . It is like a picture made of pieces of different colors. Since the `AKT1` gene mutation only affects some cells in the body, the disease also affects only part of the body.
How do doctors diagnose this?
Your doctor will perform a physical exam to diagnose Proteus syndrome. They will also use a special checklist of symptoms that are specific to the condition. For a doctor to consider this diagnosis, three common symptoms must be present. They are:
- Mosaic distribution : This means that the growths are spread out over a wide area of the body. Some parts of the body have growths, while others do not.
- Sporadic occurrence : This means that no one else in your family has these symptoms.
- Progressive course : This means that over time, the appearance of the affected body parts has changed significantly due to this excessive growth.
In addition to this, your doctor will look for other specific symptoms. To be diagnosed with Proteus syndrome, you must have specific symptoms from each of the categories on the doctor's checklist.
### What kind of tests are done?
The gene mutation that causes Proteus syndrome is not present in every cell in the body. Therefore, genetic testing can be a bit complicated. This is because the mutation may be absent in a blood sample, or may only be present in very small amounts.
However, doctors can detect this mutated gene by taking a small sample of your affected tissue (biopsy) and testing it (DNA testing) . The DNA from that sample is used to detect the mutated gene.
Is there a treatment for this? Can it be cured?
Unfortunately, there is no cure for Proteus syndrome . Treatment is focused on managing your specific symptoms. You will need to work with a team of specialists to help you with your individual medical needs.
- An orthopedic surgeon will treat your bone problems. There are various treatments to reduce bone growth in your hands, feet, and fingers. They can also correct problems with your spine and joints. Before any surgery, you will be evaluated by a hematologist to assess your risk of blood clots.
- You may need to see a dermatologist for excess sebum and skin changes. Some problems may require immediate and frequent treatment. For other problems, your doctor may take a "wait and see" approach. That is, they will monitor your condition before recommending any specific treatment.
Other healthcare providers who may be involved in your care include:
- A specialist in rehabilitation medicine (Physiatrist)
- A doctor who specializes in respiratory diseases (Pulmonologist)
- Physical therapist
- Occupational therapist
- A person who makes specialized footwear and foot supports (Pedorthist)
Scientists have only recently discovered the gene that causes Proteus syndrome, which could lead to major advances in the development of new drugs and other treatments.
Is there a way to prevent this?
No, Proteus syndrome cannot be prevented. This is because it is a genetic condition. The gene mutation that causes it is a random event during fetal development. It is not caused by anything that happened before or during pregnancy. So don't worry about it.
How is life expectancy?
The life expectancy of someone with Proteus syndrome depends largely on the parts of the body affected and the severity of the condition. Complications can be life-threatening , and they are more likely to cause death than the disease itself. These complications can include deep vein thrombosis (DVT), pulmonary embolism, and cancer. Pulmonary embolism is the most common cause of death in people with Proteus syndrome.
Overall, about 25% of people with Proteus syndrome die before the age of 22. However, those with mild symptoms generally have a good life expectancy with effective treatment.
How to live with Proteus Syndrome?
Living with the physical changes caused by Proteus syndrome can be very frustrating and difficult. It is important for you and your family to learn as much as possible about this condition. Talking to other people who are dealing with this condition and listening to their experiences can help you feel that you are not alone and that there are people who understand you. Ask your doctor about resources that can help you manage and cope with your condition.
Finding out that you or your child has a rare genetic condition can be a scary and traumatic experience. It can be especially difficult if the condition causes significant physical changes. Therefore, it is essential to find a doctor who can accurately diagnose Proteus syndrome and assemble a team of specialists. With appropriate treatment, most people have a good life expectancy. It is also important to find a group of people who can support you as you face this difficult diagnosis.
