20 year-old puzzle solved through genetic advances:

A genetic corneal dystrophy disorder

Researchers from the University of Liverpool have identified a specific gene that plays a key role in an inherited eye disorder.

The discovery solves a 20 year-old puzzle for a family in Liverpool who all developed epithelial recurrent erosion dystrophy (ERED), a genetic corneal dystrophy disorder that causes abnormality of the outer layer of the eye.

Corneal dystrophies may not cause symptoms in some individuals; in others they may cause significant vision impairment. These disorders are caused by many different genes some of which are known but many have yet to be identified.
