Marfan Syndrome

Marfan Syndrome is an autosomal dominant disease. It is caused by the misfolding of fibrillin-1, a glycoprotein which forms elastic fibers in connective tissue and contributes to cell signaling activity by binding to and sequestering transforming growth factor beta.

Two Interesting Facts

Marfan syndrome is named after Antoine Marfan, the French pediatrician who first described the condition in 1896 after noticing striking features in a five-year-old girl. The gene linked to the disease was first identified by Francesco Ramirez at the Mount Sinai Medical Center in New York City in 1991.


Marfan syndrome is one of the most common inherited disorders of connective tissue. It is an autosomal dominant condition occurring once in every 10,000 to 20,000 individuals.
