Marfan Syndrome Pedigree Chart
Marfans/ehler danlos: Marfan syndrome is a connective tissue disorder, tissues that strengthen bodies structures. In most cases it is inherited condition, but approx 30% of patients have no family history tall arms and height, affects lungs, heart and aorta, eyes causing cataract, skin problems, and tissue covering the spinal chord.
Genetic mutation: Marfan syndrome is caused by a gene mutation (in the fbn1 gene). A mutation leads to defective, weakened connective tissue throughout the body. Symptoms show up in the parts of the body where shape and structural integrity relies a lot on the weakened type of connective tissue.See 1 more doctor answer
Genetic disorder: Fbn1 gene controls connective tissue metabolism. If there are mutations or repeats, then marfa's will result. The symptoms are the result of malformed collagen. So dislocated lens in eye, heart valve problems, scoliosis, pneumothorax, artery problems may occur. Most cases are inherited, but occasionally marfan's occurs from a spontaneous mutation. This gene can be tested for in a blood specimen.See 1 more doctor answer
See the details: If you are tall, have very flexible joints, have any issues with the lenses of your eyes as well as other numerous finding on exam, you may have it. Have your doctor take a look or refer you to a rheumatologist.
Www. Marfan. Org: Fibrillin-1 gene defect leads to inefficient connective tissue building. It is inherited 70% of time. Symptoms occur in any organ that is dependent on healthy connective tissue such as the heart, lungs, skin, eyes. Marfans are tall people with thin narrow face, scoliosis, heart disease, small jaw, spidery fingers, flat feet, abnornal chest bone. You should see your dr if you suspect having it.
Long arms, fingers: Tall, thin appearance. Pigeon chest (pectus carinatum), long fingers (arachnodactyly), dilated aorta (seen on echocardiogram). Dislocated lens in the eye. Severe near sightedness. Scoliosis. Flat feet. High arched palate. Thin head with small cheekbones. Most symptoms involve heart, musculoskeletal and eyes. It is inherited in an autosomal dominant fashion.
Having the features: Features suggestive of marfan syndrome include: above-average height, long arms, long fingers, flat feet, high-arched palate, narrow face, crowded teeth, small lower jaw, pectus carinatum (pigeon chest), pectus excavatum (sunken chest), hunchback (hunchback), scoliosis (crooked back), hypermobile/hyperflexible joints, etc... A person with several of these features can see a doctor for evaluation.See 1 more doctor answer
Maybe not: A marfan syndrome woman has a 50% chance of having a marfan syndrome baby, if the father of the baby is "normal". During pregnancy, the woman needs close monitoring because she is at increased risk of rupturing her aorta (often fatal). For these reasons, she may not want to become pregnant.See 1 more doctor answer
See a geneticist: There are many options for genetic testing for marfan syndrome, but for a baby the best answer comes not from tests but from a careful history, family history, and physical examination. Sifting through the information and making sense of it in light of the new diagnostic guidelines (the 2010 ghent criteria) may show you that testing makes sense - or maybe not. Your clinical geneticist can help.
Varies by severity: People with mild marfan syndrome symptoms probably live a pretty normal lifespan. Those with severe symptoms can die from heart valve problems, rupture of the aorta, tension pneumothorax, etc..., before they reach old age. Of course, those with moderate symptoms will have a lifespan in between.See 1 more doctor answer
Doctors can evaluate: A person who may have marfan syndrome should see his doctor and a geneticist to confirm the diagnosis. If confirmed, he can get more information from the national marfan foundation website. He should also see specialists, such as a cardiologist to check the heart and aorta, an ophthalmologist to check the eyes, etc... He can notify his relatives to check their aortas, etc...See 1 more doctor answer
