Outlook / Prognosis What is the prognosis (outlook) for people with Usher syndrome? Although Usher syndrome doesn’t have a cure, children with Usher syndrome can live full and happy lives. [my.clevelandclinic.org]

Prognosis The prognosis mainly depends on the progression of the visual loss: blindness occurs in almost all cases between 50 and 70 years of age. The documents contained in this web site are presented for information purposes only. [orpha.net]

Summary Epidemiology Prevalence is estimated at 1/30,000. US is the most common cause of hereditary combined deafness-blindness. Clinical description Onset usually occurs during childhood. [orpha.net]

Epidemiology The incidence is about 1 in 25,000. About 3-6% of hearing impaired children have the condition. Types 1 and 2 are more common than type 3 and together account for 90-95% of Usher's syndrome and about 10% of all children born deaf. [patient.info]

Prevention Can Usher syndrome be prevented? Usher syndrome occurs because of the genes you inherit. At this time, there is no way to prevent it. Genetic testing can determine if you and your partner both carry the gene. [my.clevelandclinic.org]
