Marfan's Syndrome

Marfan's syndrome is a disorder of connective tissue, the tissue that strengthens the body's structures. Disorders of connective tissue affect the skeletal system, cardiovascular system, eyes, and skin. Marfan's syndrome is usually caused by a change or mutation in the genetic material in the fibrillin 1 gene on chromosome 15. This gene is responsible for making a special protein called fibrillin. Fibrillin is an important part of connective tissue in the body. Marfan's syndrome is autosomal dominate meaning the gene in question is located in one of the autosomes (a numbered pair of chromosomes 1 through 22 in this case chromosome 15).Dominate means that only one gene from a parent is required to pass down the trait of disorder.
