- Marfan syndrome (also called Marfan's syndrome) is a genetic disorder of connective tissue. It has a variable clinical presentation, ranging from mild to severe systemic disease. The most serious manifestations involve defects of the heart valves and aorta, which may lead to early death if not properly managed.

- Mutations in the FBN1 gene cause Marfan syndrome. The FBN1 gene provides instructions for making a protein called fibrillin-1. Fibrillin-1 attaches (binds) to other fibrillin-1 proteins and other molecules to form threadlike filaments called microfibrils.Microfibrils become part of the fibers that provide strength and flexibility to connective tissue.he FBN1 gene provides instructions for making a protein called fibrillin-1.

Description An additional characteristic of Marfan syndrome is swelling of the membrane that surrounds the brain and spinal cord. This is called dural ectasia and many people with Marfan syndrome have it. Dural ectasia may cause low back and leg pain, abdominal pain, and headaches.

What is Marfan Syndrome? 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. Connective tissue is made up of proteins.

- People at highest risk for Marfan syndrome are those who have a family history of the condition. If you have Marfan syndrome, you have a 50 percent chance of passing the altered gene to each of your children. Marfan syndrome affects about 1 out of every 5,000 people in the United States.

Alone we are rare. Together we are strong.â¥ Donate Today Not everyone who has a mutation of this gene develops the symptoms of Marfan syndrome. Investigators have determined that most cases (> 95%) of Marfan syndrome occur due to mutation of the FBN1 gene located on the long arm (q) of chromosome 15 (15q21.1). Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual.

- Marfan syndrome is caused by a defect in the gene that encodes the structure of fibrillin and the elastic fibers, a major component of connective tissue. This gene is called fibrillin-1 or FBN1.

- Because connective tissue is found throughout the body, patients with Marfan syndrome have problems with a number of systems including bones, joints, eyes, heart, blood vessels, nervous system, skin, and lungs. Marfan syndrome affects both sexes and all ethnic groups. However, it is relatively rare.

Heart disease guide Around three-quarters of people with Marfan syndrome inherit it from one of their parents. Because it is possible to inherit the condition when only one parent has it, there is a 1 in 2 chance that a child of a parent with Marfan syndrome will have it too. However, in some cases Marfan syndrome develops when neither of a person's parents has it. Marfan syndrome diagnosis

- Marfan syndrome may be diagnosed prenatally, at birth, or well into adulthood. Neonatal presentation is associated with a more severe course than that associated with other presentations. Most clinical features are specific to age, and some features may not manifest until relatively late in life.

Dr. Harold Schwartz on Lincoln and the Marfan Syndrome Dr. Harold Schwartz on Lincoln and the Marfan Syndrome. Dr. Harold Schwartz is a cardiologist from Huntington Park, California who, while treating a patient in 1959, discovered a common lineage between the male patient and Abraham Lincoln. While Marfan syndrome, a disorder of the connective tissue of the body, is a genetically inherited disease, Dr. Schwartz worked to analyze and piece together the connection linking both Lincoln and the boy.
