Taking a Look at Marfan Syndrome

Decent Essays

Marfan Syndrome, which is named after Antoine Marfan who first described the disorder in 1896, is a genetic disorder that affects the connective tissues found throughout the body. This syndrome can affect many different parts of the body, but the most commonly affected are the heart, blood vessels, bones, joints, respiratory system, nervous system, and eyes. Thankfully, a person’s intelligence is never affected. Marfan syndrome affects people from all races and ethnic backgrounds, and this often makes it hard to detect. It is a pretty rare genetic disorder affecting only about 1 in every 5,000 people.
This syndrome is from a mutation of a gene on chromosome 15 and this causes problems in the production of fibrillin-1 which is a protein that is an important part of connective tissue. The name for the gene is FBN1. Basically, it is the “glue” that helps to support the tissues in the human body. A child born to a parent with this syndrome has a 50% of having it. However, in the remaining 25%, neither parent has the disease which gives them a 1 in 10,000 chance of having a child with this disorder. When a child of two unaffected parents is born with it then the genetic mutation occurs in either the egg or sperm cell at the time of conception.
The defect of this “glue” leads to phenotypes such as a thin, lanky build, flexible joints, sunken eyes, a chest that is sunken in or bulges out, curvature of the spine to one side (scoliosis), and flat feet. There are other
