What Are the Symptoms of Marfan Syndrome?


To diagnose Marfan syndrome, your doctor will check your heart to see if there are any abnormalities. For example, an echocardiogram can help determine whether there are valve problems, aortic dissection, or aneurysms. He may also check for other conditions, such as dural ectasia, a bulging lining of the spinal column that can be associated with back pain. These conditions can support the diagnosis of Marfan syndrome but are not specific.

Fibrillin-1 gene mutations

Fibrillin-1 (FBN1) gene mutations have been associated with Marfan syndrome, a hereditary connective tissue disorder. The FBN1 gene produces fibrillin monomers that inhibit the formation of microfibrils, a characteristic of connective tissues. As a result, patients with FBN1 mutations display defects in the skeletal and ocular tissues, and the disease is often inherited.

Fibrillin-1 gene mutations result in an abnormal fibrillin protein, which can no longer function usually. In addition, these mutations reduce the amount of fibrillin-1 produced by the cell and impair its transport out of the cell. This results in a severe decrease in the amount of fibrillin-1 available for forming microfibrils, a characteristic of the condition. This lack of microfibrils causes the activation of excess TGF-b growth factors, resulting in a deterioration of the elasticity and stability of many tissues.

While the MFS gene mutations often cause the condition, other genetic factors can lead to this disorder. Genetic testing can confirm whether an individual has Marfan syndrome.

Mitral valve prolapse

Mitral valve prolapse (MVP) is common in patients with Marfan syndrome. It may develop slowly in some patients or may occur suddenly in others. Although mitral valve prolapse symptoms are similar to those of many other conditions, it is essential to see a doctor if they develop suddenly or worsen.

The incidence of MVP is lower than previously thought in individuals with Marfan syndrome, but its prevalence has increased. Patients with MVP have an abnormally sizeable sinotubular junction and an enlarged LA dimension. Their MV is also more prone to regurgitation. The current nosology uses several systemic Marfan-like features to diagnose this disease. However, these findings do not seem to affect clinical outcomes. Therefore, more prospective studies with a longer follow-up are needed to determine the cause and diagnosis of MV.

While there are several treatments for mitral valve prolapse in people with Marfan syndrome, the first step is determining whether your condition is causing the problem. An abnormality in the heart valve causes mitral valve prolapse. A faulty valve causes leaking fluid into the heart and may result in mitral regurgitation and heart failure. In such cases, surgery is required to fix the defect.

Cardiovascular malformations

Cardiovascular malformations are one of the most common features of Marfan syndrome. Typically, these malformations involve the aorta. However, in some cases, the disease affects only the heart. In this case, the condition may be associated with other cardiovascular conditions. The most common cardiac malformations in Marfan syndrome are aortic regurgitation and mitral regurgitation.

Cardiovascular malformations are one of the most common complications of Marfan syndrome, although they are usually mild in early childhood. The most common abnormalities are dilatation of the aorta and aortic root, but other valve abnormalities can also occur. These valve abnormalities increase the risk of infective endocarditis in children with Marfan syndrome. In addition to cardiac disease, skin sepsis is a common complication.

Patients with Marfan syndrome should have routine follow-up visits with their physicians. These visits should include cardiovascular tests and eye exams. Surgery may sometimes be needed to repair the aorta or fix a mitral valve defect. Patients may also have to take specialized tests, such as MRI scans.

Dural ectasia

Dural ectasia is one of the most common signs and symptoms of Marfan syndrome. This condition affects the spinal cord and is one of the primary criteria for diagnosing the syndrome. Patients with this condition may experience low back pain, headache, and weakness in the proximal leg. Patients may also experience pain in the genital area or rectum. These symptoms are usually moderate to severe and occur several times a week. Patients typically experience these symptoms while sitting or standing upright. Even if the patient can rest in a recumbent position, they may not experience relief from their symptoms.

In addition to these common symptoms, dural ectasia may be associated with several other medical conditions. For instance, dural ectasia in Marfan syndrome can affect the peripheral nerves and the spinal cord. If the affected organs are damaged, it may lead to a weakened nervous system, resulting in decreased ability to function and a reduced sense of well-being.


Marfan syndrome treatment focuses on preventing and reversing skeletal defects associated with the disorder. It also involves physical therapy to improve muscle strength. Children with the disorder typically require regular physical exams and monitoring. They may also require orthopedic braces. Treatment may also include corrective surgery. If left untreated, Marfan syndrome can compromise heart and lung function.

Marfan syndrome patients may also need valve surgery to repair a leaky aortic valve. This procedure can be performed using minimally invasive methods or traditional techniques. Patients should choose a skilled heart surgeon to perform the procedure. After surgery, patients still require regular follow-ups and preventive measures to prevent heart failure in the future.
