Marfan syndrome........People with Marfan's tend to be unusually tall, with long limbs and long, thin fingers.
Marfan syndrome! caused by defects in a gene fibrillin-1. Fibrillin-1 plays an important role as the building block for elastic tissue in the body. The gene defect also causes too much growth of the long bones of the body. This causes the tall height and long arms and legs seen in people with this syndrome. How this overgrowth happens is not well understood.
