What Is Usher Syndrome?
Usher syndrome is the most common genetic condition that affects both vision and hearing. The major symptoms of Usher syndrome are hearing loss and vision loss from an eye disorder called retinitis pigmentosa, or RP (see illustration).
Vision loss from RP can begin anywhere from early childhood to adolescence.
Who is at risk for Usher syndrome?
Usher syndrome is a recessive disorder, which means that a person has to inherit the change in the gene from both parents. A person who inherits the changed gene from one parent does not have the syndrome but is a carrier for it. When two carriers of the same Usher syndrome gene have a child together, there is a one-in-four chance that the child will have Usher syndrome.
