Marfan syndrome

Marfan syndrome (or Marfan's syndrome) is a genetic disorder of the connective tissue affecting about 0.02% of the population....People with Marfan's are typically tall, with long limbs and long thin fingers.

Although there are no unique signs or symptoms of this syndrome, the constellation of long limbs[arm span being more than ur length by 5cm], dislocated lenses[one inside ur eyeballs], and aortic root dilation is sufficient to make the diagnosis with confidence. There are more than thirty other clinical features that are variably associated with the syndrome most involving the skeleton, skin, and joints

Olympic champion Michael Phelps [swimmer] is rumored[!] to be suffering from this though not proven yet!...

First time for me to hear it...is this what we commonly refer to as giantism, or this is another case?

Any known causes? Or just simply genetics?

I saw this case today. He has pan systolic murmur with a mid-systolic click; a very hyperdynamic chest with dancing carotids. He has fever too, bacterial endocarditis suspected. Also, he has dolicocephaly, high arched palate and defective left eye; joints are hyperextensible.
