Usher Syndrome

Usher syndrome is an inherited disease characterized by hearing loss and progressive vision loss. Damaged proteins are unable to maintain healthy cells in the ear, important for both hearing and balance, and healthy cells in the eyes important for sight. Researchers have divided Usher syndrome into three types (and further subtypes) depending on the age of onset and severity of symptoms. The different Usher syndromes are caused by different damaged proteins and may have varying severity. View testing options
