For healthcare providers: Additional clinical information

Marfan syndrome is a genetic disorder of the connective tissue.  Connective tissue crisscrosses the body, within muscles and organs, holding them in place like glue, and helping to control how the body grows. In Marfan syndrome, the connective tissue doesn’t grow correctly. 

This condition occurs in males and females equally, in all races, and has a high degree of variability, even within a family. All organs contain connective tissue, so it can affect any part of the body. Typically this condition affects the heart, eyes, lungs, and bones. It does not affect cognitive function. Marfan condition can be life threatening. 

About 1 in every 5,000 babies is born with Marfan syndrome.
