- Marfan syndrome (MFS) is a genetic disorder of the connective tissue. The degree to which people are affected varies. People with Marfan tend to be tall, and thin, with long arms, legs, fingers, and toes. They also typically have flexible joints and scoliosis.

Alone we are rare. Together we are strong.â¥ Donate Today Marfan syndrome is inherited as an autosomal dominant trait, meaning that only one abnormal copy of the Marfan gene inheited from one parent is sufficient to have the condition. Defects or disruptions (mutations) of the fibrillin-1 (FBN1) gene have been linked to Marfan syndrome and related disorders.

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.The protein that plays a role in Marfan syndrome is called fibrillin-1.

Heart Disease and Marfan Syndrome One of the biggest threats of Marfan syndrome is damage to the aorta, the artery that carries blood from the heart to the rest of the body. Marfan syndrome can rupture the inner layers of the aorta, causing dissection that leads to bleeding in the wall of the vessel. Aortic dissection can be deadly.

- 17 these early histological findings, and the identifica-tion of FBN1 as the gene involved, led to the first theo-ries on the pathogenesis of Marfan syndrome. 22–24 early hypotheses attributed a mere structural role to fibrillin-1.

Fibrillin Mutations Yet, studies of people with Marfan syndrome consistently show that a large percentage of them are not found to have any fibrillin-1 mutations. In 1997, a study of 60 Marfans found that only 28% of the people with the disorder had fibrillin-1 mutations.ssociation does not prove cause and effect. Fibrillin-1 mutations have also been found in people who have aortic aneurysms, mitral valve prolapse or skeletal features of Marfan syndrome, such as scoliosis or pectus excavatum (Robinson, 2000).

Spanish flu research Altogether, only a handful of mutations may need to take place in order for H5N1 avian flu to become a pandemic virus like the one of 1918. However it is important to note that likelihood of mutation does not indicate the likelihood for the evolution of such a strain; since some of the necessary mutations may be constrained by stabilizing selection.

Marfan syndrome Marfan syndrome usually is inherited. This means the gene change that causes Marfan syndrome is passed from parent to child. If one parent has Marfan syndrome, there’s a 1-in-2 chance (50 percent) that their baby will have it, too. Only babies who get the gene change have Marfan syndrome.

Marfan syndrome Estimates indicate about one in 3,000 to 5,000 individuals have Marfan syndrome. Each parent with the condition has a 50% risk of passing the genetic defect on to any child due to its autosomal dominant nature. Most individuals with Marfan syndrome have another affected family member.

Background Marfan syndrome (MFS) is an inherited connective tissue disorder, noteworthy for its worldwide distribution, relatively high prevalence, and clinical variability, as well as pleiotropic manifestations involving primarily the ocular, skeletal, and cardiovascular systems, some of which are life threatening.

Alone we are rare. Together we are strong.â¥ Donate Today Marfan syndrome is inherited as an autosomal dominant condition. Dominant genetic disorders occur when only a single copy of an abnormal gene is necessary to cause a particular disease. The abnormal gene can be inherited from either parent or can be the result of a new mutation (gene change) in the affected individual. In approximately 25-30 percent of Marfan syndrome cases, this mutation occurs as the result of a new mutation.

Vicks VapoRub: An effective nasal decongestant? Swallowing a few teaspoons of camphor — one of the main ingredients in VapoRub and other topical medications, such as Campho-Phenique and Bengay — can cause fatal poisoning in toddlers. Topical camphor absorbed through mucous membranes or broken skin also can be toxic.
