With the measure of the radius, you can tell a lot about the circle: its diameter (the distance from one side to the other, passing through the center), its circumference (how far around it is), and its area (how many square inches, feet, yards, meters â what have you â fit into it).
Marfan syndrome (also called Marfan's syndrome) is a genetic disorder of connective tissue. It has a variable clinical presentation, ranging from mild to severe systemic disease. The most serious manifestations involve defects of the heart valves and aorta, which may lead to early death if not properly managed.
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, thereâs a 1-in-2 chance (50 percent) that their baby will have it, too. Only babies who get the gene change have Marfan syndrome.
