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. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.

Gastroschisis is a birth defect of the abdominal (belly) wall. The baby’s intestines stick outside of the baby’s body, through a hole beside the belly button. The hole can be small or large and sometimes other organs, such as the stomach and liver, can also stick outside of the baby’s body. Gastroschisis occurs early during pregnancy when the muscles that make up the baby’s abdominal wall do not form correctly. A hole occurs which allows the intestines and other organs to extend outside of the body, usually to the right side of belly button. Because the intestines are not covered in a protective sac and are exposed to the amniotic fluid, the bowel can become irritated, causing it to shorten, twist, or swell.
