what is marfan syndrome
Marfan syndrome is a genetic disorder that affects the bodyâs connective tissue. Connective tissue holds all the bodyâs cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly.Connective tissue is made up of proteins.The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1.ut 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.
