- Hearing Impairment
Hearing impairment in USH2A was compared with that in USH1B to see whether these genotypes can be distinguished by their hearing impairment. We also looked for progression of hearing impairment in the patients with USH2A. [jamanetwork.com]
Patients diagnosed with USH2A have congenital hearing impairment that ranges from moderate to severe and experience progressive vision loss beginning in the second decade of life. [scholarsbank.uoregon.edu]

Treatment
Sensitive, objective outcome measures of retinal degeneration will greatly facilitate development of treatments for Usher syndrome patients. [clinicaltrials.ucsf.edu]
There are currently no treatments for the vision loss associated with these inherited retinal diseases. [eyewire.news]
The goal of the treatment is to stop disease progression and potentially restore some peripheral vision. [blindness.org]

Our understanding of, and ability to test for, the underlying etiology of syndromes has been greatly enhanced by the study of the human genome and proteins necessary for normal development. [asha.org]
Since they thought the etiology of the hearing loss was Connexin 26, no one ever mentioned Usher or looked into it. At age 12, the female twin starting having difficulty with her night vision. She wore corrective lenses as well. [audiologyonline.com]
There can be several etiologies behind deafblindness, but Usher syndrome is one of the most common causes ( Pennings, 2004 ; Sadeghi, 2005 ). [journal.frontiersin.org]
Epidemiology
Authored by 60 internationally recognized researchers, the book describes the normal development of the ear, updates the classification and epidemiology of hearing loss, and surveys the usage of audiometric tests and diagnostic medical examinations. [books.google.com]
Chapters on epidemiology, embryology, non-syndromic hearing loss, and syndromic forms of hearing loss have all been updated with particular attention to the vast amount of new information on molecular mechanisms, and chapters on clinical and molecular [books.google.es]
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
In this study, we explored the potential of antisense oligonucleotides (AONs) to prevent aberrant splicing of USH2A pre-mRNA as a consequence of the c.7595-2144A>G mutation. [repository.ubn.ru.nl]
