Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly.
About 1 in 5,000 people have Marfan syndrome, including men and women of all races and ethnic groups. About 3 out of 4 people with Marfan syndrome inherit it, meaning they get the genetic mutation from a parent who has it. But some people with Marfan syndrome are the first in their family to have it; when this happens it is called a spontaneous mutation. There is a 50 percent chance that a person with Marfan syndrome will pass along the genetic mutation each time they have a child.
Every person’s experience with Marfan syndrome is slightly different. No one has every feature and people have different combinations of features. Some features of Marfan syndrome are easier to see than others. These include:
are not related to weight gain or loss
Harder-to-detect signs of Marfan syndrome include heart problems, especially those related to the aorta, the large blood vessel that carries blood away from the heart to the rest of the body. Other signs can include sudden lung collapse and eye problems, including severe nearsightedness, dislocated lens, detached retina, early glaucoma, and early cataracts. Special tests are often needed to detect these features.
