Marfan Syndrome
http://www.nhlbi.nih.gov/health/dci/Diseases/mar/mar_whatis.html
What Is Marfan Syndrome?
Marfan syndrome is a disorder of connective tissue. Connective tissue holds all the parts of your body together and helps control growth. Connective tissue gets some of its strength from a protein called fibrillin 1. Fibrillin 1 also plays an important role in controlling the growth and development of the body. In Marfan syndrome, the body produces fibrillin 1 that does not work properly. As a result, the connective tissue is not as strong as it should be, and the growth and development of the body are affected.

Effects of Marfan Syndrome on the Body
The Heart and Blood Vessels
Most people who have Marfan syndrome have problems with their heart and blood vessels because of weak connective tissue.

Valves in the heart may not close properly and may let blood leak backward. The aorta––the large artery that carries blood away from the heart out to the body––may stretch and enlarge, and it can burst. The aorta also can develop a tear in its inner wall. This tear can expand and block blood flow through the aorta. This is called aortic dissection.

The Bones, Cartilage, and Ligaments
People with Marfan syndrome tend to have tall and slender bodies with arms and legs disproportionately long compared to the trunk. They also usually have long fingers and toes. The ligaments and joints are typically loose. Because of rib overgrowth, the chest may protrude or be indented. Abnormal curving of the spine, called scoliosis (sko-le-O-sis), lordosis (lor-DO-sis), or kyphosis (ki-FO-sis), can occur.

The Eyes
The most common vision problem in people with Marfan syndrome is nearsightedness (myopia). Nearsightedness is sharp vision for things that are close and blurred vision for things that are farther away. Dislocation of the lens of the eye is a hallmark of Marfan syndrome that occurs in very few other conditions. Cataracts, or glaucoma at an early age, or detached retinas, also occur in people with Marfan syndrome.

The Lungs
In Marfan syndrome, the air sacs in the lungs may be unusually large. In addition, the chest may be abnormally shaped. For these reasons, people with Marfan syndrome may have breathing problems, such as collapsed lungs (spontaneous pneumothorax) and early emphysema.

The Skin
Stretch marks, not due to weight gain or loss, commonly occur on the skin of people with Marfan syndrome.

More details about these characteristics and complications of Marfan syndrome are in the Signs and Symptoms section.

Outlook
Marfan syndrome is a lifelong disorder with no known cure. As recently as the 1970s, most people with Marfan syndrome did not survive beyond age 40–50. Some infants and children died from complications due to the condition. In most cases, death was due to heart and blood vessel problems.

Today, because of early diagnosis and better medical and surgical treatments, people with Marfan syndrome can live longer and healthier lives, with fewer and less severe complications. However, aging with Marfan syndrome poses new concerns as this chronic and progressive disorder advances. In addition, those who are not diagnosed or treated are still at risk of an early sudden death due to blood vessel problems.

On a personal note, one of my sisters [now 48] has been diagnosed with this, and has aortic problems...nothing at this time is serious, but she is aware of what she has to watch out for.
I think my dad [now an 80 year old..in very good physical shape with a good mind and sharp wit] has it...a few years ago he had surgery for an aortic aneurysm, and if it were not for an extremely competent surgeon (and team!) we would have lost hhim on the operating table last March because his aorta distended unexpectantly (during another surgery) [ and was quickly replaced ] during a routine carotid artery "cleaning".
Anyways, he's doing very well now!

What I am trying to say, if you think you have symptoms, please
see a doctor or health care provider to at least be diagnosed.
And you know what to be aware of. My sister and dad are true role models, in my eye. Both follow doctor's orders but don't dwell on what they don't have control over, and live life fully.

"Symptoms

The most serious conditions associated with Marfan syndrome primarily involve the cardiovascular system. Marfan syndrome may cause leakage of the mitral or aortic valves that control the flow of blood through the heart. This may produce shortness of breath, an irregular pulse, and undue tiredness. Another complication is cystic medial necrosis predisposing to dissecting aortic aneurysm.

Marfan syndrome sufferers may grow to larger than normal height, and typically have long, slender limbs and fingers. Sometimes the fingers have a long, thin, spidery appearance known as arachnodactyly. In addition to affecting height and limb proportions, Marfan syndrome may produce other skeletal symptoms. Curvature of the spine (scoliosis) is a common problem, as is abnormal indentation (pectus excavatum) or protrusion (pectus carinatum) of the sternum. These symptoms may in turn cause unusual pressure on the heart and lungs. Other symptoms include; abnormal joint flexibility, high palates, small jaws, flat feet, stooped shoulders, unexplained stretch marks, and dislocation of the optic lens in the eye (ectopia lentis). Some people with Marfans have speech impediments as a result of the high palates and small jaws.

Nearsightedness or myopia is a common condition associated with Marfan syndrome. In addition, the weakening of connective tissue often causes detachment of the retina and/or displacement of the lens in one or both eyes.[4]

Dural ectasia is a major indicator of Marfan syndrome. It is a dilation of the dural sac surrounding the spinal cord. It can cause lower back and leg pain, headaches, and other neurological symptoms. It can be present without symptoms.

Marfan syndrome can often be confused with Loeys-Dietz syndrome, a highly similar connective tissue disorder resulting from mutations in the TGF-beta receptor genes TGFBR1 or TGFBR2."

between the further enduring theories about President Lincoln's wellness arose interior the early Nineteen Sixties. A wellness care service released a paper in 1964 interior the mag of the yankee medical association which stated that President Abraham Lincoln had Marfan syndrome, a connective tissue ailment. The diagnosis replaced into once based on actual observations of Lincoln: the actuality that he replaced into once lots taller than a lot men of his day had lengthy limbs had an abnormally-shaped chest (sunken in) had loose (lax) joints (based on written descriptions) considering that then, diverse physicians have disputed a diagnosis of Marfan syndrome for Lincoln. some have argued that President Lincoln's palms did no longer have lengthy, skinny palms, a common researching in those with the syndrome. At a medical workshop held in October 2001 in Cairo, Egypt, the scientists accrued there felt that there replaced into once now no longer adequate medical info on hand to obviously diagnose President Lincoln with the ailment.
