To screen for Marfan syndrome, your doctor may do a physical exam, including a check for certain body features common to the condition, and may ask about your symptoms.
Depending on your age, your doctor may suggest a genetic test. Siblings, parents, or children of a person who has Marfan syndrome—also known as first-degree relatives—may want to have genetic testing for the condition even if they do not have symptoms.
Other relatives, such as first cousins and half-siblings, may be tested if they have symptoms or if the family is concerned that the person may have Marfan syndrome. Learn more in Diagnosis. Couples who are planning to have children and know that they are at risk of having a child with Marfan syndrome may want to meet with a genetic counselor.
A genetic counselor can answer questions about the risk and explain the choices that are available. Signs and symptoms of Marfan syndrome depend on which parts of the body are affected and the severity of the condition. Some people have few or no signs or symptoms, while others experience severe symptoms or life-threatening complications.
Marfan syndrome most commonly affects the connective tissue of the heart and blood vessels, eyes, bones, lungs, and spinal cord. However, the condition can affect many parts of the body. The most serious complications are in the heart and aorta and may include:. Your doctor will diagnose Marfan syndrome based on your medical and family history, a physical exam, and test results.
No single test can diagnose Marfan syndrome, so doctors use a set of guidelines called the Ghent criteria to help. The Ghent criteria include whether the diameter of your aorta is larger than normal, whether your eye lens has ever moved out of place, whether you have certain physical signs of Marfan syndrome, and sometimes genetic testing.
If you are diagnosed with Marfan syndrome, all of your first-degree relatives, including parents, siblings, and children, should be screened for the disorder, even if they do not have signs and symptoms.
For example, your doctor may ask whether any of your family members have Marfan syndrome, have had an aortic aneurysm, or have had heart problems. During the physical exam, your doctor will look for signs of Marfan syndrome.
For example, he or she may check the curve of your spine and the shape of your feet. While Marfan syndrome has no cure, treatments can help delay or prevent complications, especially when started early. The type of treatment you receive will depend on what parts of your body are affected and the severity of your condition. You may have a team of doctors and specialists to coordinate your care. Your doctor may recommend blood pressure medicines to relieve any strain on or bulging of the aorta.
These medicines help your heart beat slower and with less force. If your aorta is larger than normal, your doctor may recommend surgery to repair or replace part of the aorta to prevent it from rupturing or tearing open. If you have an aortic dissection or rupture, you will need emergency surgery to repair the aorta. Your aortic valve may also be replaced with a mechanical or biological valve made from animal tissue. The valve may be replaced during the open surgery to repair the aneurysm.
If you have mitral regurgitation—where your blood flows backward into your left atrium—your doctor may recommend surgery to repair or replace your mitral valve. If you have been diagnosed with Marfan syndrome, it is important to follow your treatment plan, make healthy lifestyle changes, and get mental health support. Learn how to prevent or reduce complications in the future. If you are thinking about becoming pregnant, discuss the possible risks with your doctor.
How often you need to see your doctor for follow-up care will depend on your treatment and symptoms. Return to Treatment to review possible treatment options for Marfan syndrome. People who have Marfan syndrome may need more than one heart or blood vessel surgery over time. After surgery, you may need medicines and regular monitoring.
Follow all medical instructions given by your doctor. Recovery after open surgery may take months. To help prevent complications from Marfan syndrome, your doctor may recommend you avoid the following:. Living with Marfan syndrome may cause fear, anxiety, depression, and stress. Talk about how you feel with your healthcare team. Your doctor may recommend:. If you have Marfan syndrome, you are at risk for a life-threatening aortic dissection.
If your aorta is weaker or larger than normal, it is important to know the signs and symptoms of a dissection or rupture, which may include:. Many women who have Marfan syndrome have safe and healthy pregnancies and deliveries. However, there are some added risks during pregnancy and delivery. The most serious risk is aortic dissection due to extra strain on the heart. If you have Marfan syndrome and have already experienced aortic dissection, it is not safe for you to become pregnant. If you are thinking about getting pregnant, talk with an obstetrician, a doctor who cares for pregnant women, who is familiar with your condition and has experience with high-risk pregnancies.
Your doctor might recommend that you have surgery to fix your aorta before you try to get pregnant. Your doctor will also make sure that your medicines are safe to take during pregnancy.

After reading our Marfan Syndrome Health Topic, you may be interested in additional information found in the following resources. Marfan Syndrome. Also known as MFS. Marfan syndrome is a genetic condition that affects a protein in the body that helps build healthy connective tissues. Connective tissues support the bones, muscles, and organs in your body and allow your skin, blood vessels, and ligaments to stretch.
Some people who have Marfan syndrome have few or no signs or symptoms, while others experience serious symptoms or life-threatening complications. Symptoms of Marfan syndrome depend on which parts of the body are affected and the severity of the condition. People who have Marfan syndrome may be tall and thin with long arms, legs, fingers, and toes, as well as flexible joints. The most serious complications are problems in the heart and blood vessels, such as weakening or bulging of the aorta.
Your doctor may recommend medicines, surgery, or other treatments to manage or prevent complications. Limiting certain activities, or changing how you do them, may help reduce or prevent complications in the heart, eyes, and joints. Explore this Health Topic to learn more about Marfan syndrome, our role in research and clinical trials to improve health, and where to find more information.
Causes - Marfan Syndrome. How is Marfan syndrome inherited? Inheritance Pattern for Marfan Syndrome. This image shows how FBN1 genes are inherited.
A person inherits two copies of the FBN1 gene, one from each parent. If one parent has Marfan syndrome, each child has a 50 percent chance of inheriting a mutated FBN1 gene and having Marfan syndrome. What does fibrillin-1 do? They are also advised to avoid medications such as decongestants and foods that contain caffeine which can lead to chronic increases in blood pressure and stretch the connective tissue in the cardiovascular system. Marfan syndrome is inherited in families in an autosomal dominant manner.
Approximately seventy-five percent of individuals who have Marfan syndrome have a parent who also has the condition inherited. Approximately 25 percent of individuals who have Marfan syndrome, have the condition as a result of a new de novo mutation. When a parent has Marfan syndrome, each of his or her children has a 50 percent chance 1 chance in 2 to inherit the FBN1 gene.
While Marfan syndrome is not always inherited, it is always heritable. When a child with Marfan syndrome is born to parents who do not show features of the Marfan syndrome, it is likely the child has a new mutation. In this family situation, the chance for future siblings brothers and sisters of the child with Marfan syndrome to be born with Marfan syndrome is less than 50 percent.
But the risk is still greater than the general population risk of 1 in 10, The risk is higher for siblings because there are rare families where a Marfan gene mutation is in some percentage of the germline cells of one of the parents testes or ovaries.
Prenatal testing for Marfan syndrome is available when the gene mutation is known, and also using a technique called linkage analysis tracking the gene for Marfan syndrome in a family using genetic markers.

What are the symptoms of Marfan syndrome? How is Marfan syndrome diagnosed? There are four major clinical diagnostic features: Dilatation or dissection of the aorta at the level of the sinuses of Valsava. Ectopia lentis dislocated lens of the eye. Four of the eight typical skeletal features.
