For 10 points, name this disorder characterized by an especially tall and thin appearance.
The gene that encodes the protein de cient in this disease also encodes a protein that triggers glucose release from the liver, the protein asÂ·proÂ·sin. A series of thumb signs used to diagnose this disease are known as the Ghent criteria. The protein implicated in this disease is normally responsible for sequestering TGF-beta and formation of elastic  bers. A common result of this syndrome is myxÂ·oÂ·maÂ·tous degeneration of the mitral valve leading to prolapse. The symptoms of this disease resemble those of Ehlers-Danlos (AY-lers dahn-lohs) syndrome, a similar connective tissue disorder. This autosomal recessive disorder is caused by a defect in a protein that surrounds elastin  bers known as  brillin. For 10 points, name this disorder characterized by an especially tall and thin appearance.
