Retinitis pigmentosa first presents with night blindness, but progresses to tunnel vision and eventually blindness. [sema4.com]

Our study presents, in an objective way, the clinical differences between type I and type II Usher syndrome and between the 2 most frequent USH2A gene mutations. [jamanetwork.com]

Based on this model, we can speculate that a similar phenomenon may underlie the extremely different phenotypes of the C759F homozygotes reported in the present work. [jmg.bmj.com]

• Hearing Impairment

  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]

There are currently no treatments for the vision loss associated with these inherited retinal diseases. [eyewire.news]

Sensitive, objective outcome measures of retinal degeneration will greatly facilitate development of treatments for Usher syndrome patients. [clinicaltrials.ucsf.edu]

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 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]

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]

These mutations often lead to the production of an abnormally short version of the protein or prevent the cell from making any functional usherin. [ghr.nlm.nih.gov]
