Marfan syndrome

The thing I learned today is that Marfan syndrome is a genetic disorder of the connective tissue, which may affect heart, lungs, eyes, spinal cord, and skeleton and cause a number of complications.  People with Marfan syndrome tend to be tall with long, slender fingers; if the fingers fold over the thumb and the thumb extends past the hand that is a sign of Marfan syndrome.  The disease is named after Antoine Marfan, a French pediatrician.
