<unk> 's syndrome has for a long time been considered a synonym for Stickler's syndrome. However, since the gene that is responsible for<unk>  disease (and Erosive Vitreoretinopathie) is known (2005), the confusion has ended. For<unk>  disease is the Versican gene (VCAN) located at 5q14.3 is responsible. For Stickler there are 4 genes are known to cause this syndrome: COL2A1 (75% of Stickler cases), COL11A1 (also Marshall syndrome), COL11A2 (non-ocular Stickler) and COL9A1 (recessive Stickler). The gene involved helps regulate how the body makes collagen, a sort of chemical glue that holds tissues together in many parts of the body. This particular collagen gene only becomes active in the jelly-like material that fills the eyeball; in<unk>  this "vitreous" jelly grabs too tightly to the already weak retina and pulls it away.
