Affected individuals present with congenital deafness and a highly variable degree of retinal degeneration. Using a positional candidate approach, we identified a new member of the cadherin gene superfamily, CDH23. [ncbi.nlm.nih.gov]

In the present study, we carried out a systematic mutation screening of these genes in USH1 patients from USA and from UK. [wwww.unboundmedicine.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]

• Retinal Hemorrhage

  There was an epiretinal membrane (ERM) with retinal thickening in the macula of OD. There were no retinal hemorrhages or exudates in macula OU. [oatext.com]

• 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]

  Usher syndrome type I (USH1) is characterized by congenital, bilateral, profound sensorineural hearing loss, vestibular areflexia, and adolescent-onset retinitis pigmentosa (RP). [ncbi.nlm.nih.gov]

• Profound Congenital Hearing Loss

  Conventional hearing aids may be indicated for patients with moderate to severe hearing loss. Cochlear implants, unilateral or bilateral, are now more frequently used for patients with profound congenital hearing loss. [orpha.net]

  The disorder is divided into three clinical types: type I (USH1) characterised by profound congenital hearing loss, absent vestibular function and onset of RP usually within the first decade of life; type II (USH2), characterised by congenital, moderate [jmg.bmj.com]

• Delusion

  There is also who clinges to illusions, using numerous journeys of hope, the illusion of finding solutions to the problem, but these are constant sources of delusion, every time the person bringing a sense of frustration more and more accentuated. [noisyvision.org]

• Denial

  The impact of this new reality, it can produce attitudes ranging from depression to isolation, abandonment of the workplace and even the breaking of emotional bonds established previously, while the opposite may result in the denial of the disease pretending [noisyvision.org]

All three types are inherited in an autosomal recessive manner.[485] Treatment for the hearing loss may include hearing aids or surgery for a cochlear implant. [rarediseases.org]

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]

This information would be useful in determining the prognosis for affected patients and would assist in genetic counseling and in assigning phenotypes for molecular study. [jamanetwork.com]

Overall, the patient's genotype appears to confer better visual prognosis compared to most patients with USH1. [healio.com]

Most of these mutations disrupt protein production, resulting in an abnormally small, nonfunctional version of cadherin 23 or preventing the production of any of this protein. Less frequently, mutations change single amino acids in cadherin 23. [ghr.nlm.nih.gov]
