Unusually tall, long limbs... Maybe this is Marfan Syndrome!

Do you also feel that you are much taller and have longer arms and legs than your friends? Or do your joints break easily? Have you had to wear glasses since childhood? If one or more of these things apply to you, it may be very important for you to be aware of the condition we are talking about today, called Marfan Syndrome. Although this is a bit unfamiliar, let's talk about it simply.

Simply put, what is Marfan Syndrome?

Think of our body as a beautifully constructed building. The bricks, walls, and roof of this building are held together and made strong by cement mortar. Similarly, there is a special type of tissue that connects everything in our body, such as organs, bones, muscles, and blood vessels, and gives them the strength and flexibility they need. In medicine, we call this "connective tissue." These are like the 'gum' in our body.

Marfan Syndrome is a genetic condition. A person with this condition has weak connective tissue, or more precisely, too loose. This means that the connective tissue is less strong and elastic. Because this connective tissue is found throughout the body, Marfan Syndrome can affect several parts of our body. It can mainly affect the heart, blood vessels, eyes, bones, and joints .

Although this is a congenital condition, sometimes symptoms appear and a diagnosis is made at a young age.

What could be the symptoms of this?

The important thing to understand here is that not everyone with Marfan Syndrome will experience the same set of symptoms. It varies greatly from person to person. Some people may have many symptoms, while others may have only a few. That's why doctors call this a condition with "variable expression."

However, there are some common characteristics that can be seen. Let's break them down into two parts.

In addition to these two main characteristics, other characteristics related to the appearance of the body are often seen.

What are the complications that can occur due to Marfan Syndrome?

If this condition is not managed properly, serious complications can develop over time.

Possible effects on the heart and blood vessels

These are the complications that require the most attention in Marfan Syndrome.

• Aortic dissection: This is the most dangerous condition. The wall of the aorta is made up of several layers. A sudden tear in the inner layer of this wall can cause blood to leak between the layers. This is a life-threatening condition that requires emergency surgery.
• Heart valve disease: The valves in the heart become weak and may not close properly, allowing blood to leak backward.
• Enlarged heart: The heart muscle can become enlarged and weak because the heart has to work harder over time.
• Heartbeat irregularities (Arrhythmia): The heartbeat may become irregular.
• Brain aneurysms: A weak spot in a blood vessel in or around the brain can bulge like a balloon.

Effects on the eyes

• Cataracts
• Glaucoma
• Retinal detachment

Effects on the lungs

Weakening of connective tissue can also affect the lungs.

• Asthma
• Lung infections (Bronchitis, Pneumonia)
• Collapsed lung (Pneumothorax)

Why does Marfan Syndrome occur? What is the cause?

The main reason for this is a genetic change. There is a gene that controls the production of a protein called 'Fibrillin-1' in our body's connective tissues. It is called the `FBN1` gene. People with Marfan Syndrome have a certain change, or defect (variant), in this `FBN1` gene. Due to this, the fibrillin protein produced in the body becomes weak.

• Most often (about 75%) the defective gene is inherited from one parent. If either parent has the condition, each of their children has a 50% chance of inheriting the condition.
• In the remaining 25% of cases, the child may develop this genetic mutation even if the parents do not have the condition. The exact cause has not yet been found.

How do doctors find this?

Because Marfan Syndrome affects so many parts of the body, it may take a team of doctors from different specialties to make an accurate diagnosis . Your doctor will usually follow these steps:

• Asking about your medical history and symptoms: Asking about any discomfort you are experiencing, vision problems, or joint pain.
• A complete physical examination: measures height, weight, limb length, whether there is a backache, and the shape of the chest.
• Asking about family medical history: Asking about things like whether anyone in the family has had these symptoms, or whether anyone has died from sudden cardiac arrest.
• Referral for special tests:
• Echocardiogram (Echo test): This is the most important test. It can check the condition of the heart and aorta, and the function of the valves.
• Electrocardiogram (ECG): Check for heart rhythm irregularities.
• CT or MRI scans: See the entire length of the aorta and other blood vessels in detail.
• An eye exam: Identify the position of the lens of the eye and other problems.
• Genetic test: A blood sample can be taken to determine if there is a defect in the `FBN1` gene.

What are the treatments for this?

First of all, there is no cure for Marfan Syndrome. But don't worry. It is possible to manage it well, prevent complications, and live a normal, healthy life. The main goal of treatment is to control symptoms and prevent dangerous complications.

Medications

• Beta-blockers: These drugs slow the heart rate slightly, lower blood pressure, and reduce the pressure on the aorta. This can slow down the rate at which the aorta dilates.
• Angiotensin II Receptor Blockers (ARBs): These drugs also help protect the aorta.

Routine Monitoring

This is the most important part of management. You have to see the doctor on a regular schedule and get tested.

• Heart and blood vessels: An echo test is performed at least once a year to check for changes in the size of the aorta.
• Eyes: You should have your eyes checked regularly by an ophthalmologist.
• Skeletal system: You also need to pay attention to things like your spine.

Advice on physical activity

Exercise is good for someone with Marfan Syndrome, but not all exercise is good. Some intense exercises can put pressure on the aorta. Therefore, it is essential to talk to your doctor to find out what exercises are right for you.

Heart Surgery

If the aorta becomes dangerously wide, doctors may recommend surgery to remove the weak part and insert a graft before it ruptures. If the heart valves are damaged, surgery may be performed to repair or replace them.

Life and mental health with Marfan Syndrome

Living with Marfan Syndrome can be challenging at times. Constantly seeing doctors, taking medications, and making lifestyle changes can be tiring.

And also,

• Thinking about your body's appearance can cause anxiety.
• Frequent body aches and fatigue.
• When you can't play sports, run around, and play like other people, you can feel like you're socially isolated.
• Things like the future and starting a family can cause fear.

For these reasons, there is a risk of developing mental problems such as anxiety and depression .

Thanks to the knowledge we have about Marfan Syndrome and new treatments, the life expectancy of someone with this condition is now much more similar to that of the average person. The most important thing is to identify the disease early and manage it properly.
