Usher Syndrome Type 1J

Usher Syndrome 1J


Presentation

  • Results: : All individuals with MYO7A mutations presented with features consistent with Usher type 1.[iovs.arvojournals.org]
  • Overlapping and atypical presentations have been described for all three types of Usher syndrome. For example some individuals with mutations in type I genes may have a milder presentation (moderate hearing loss and/or a normal vestibular system).[usher-syndrome.org]
  • Over several years the blinds spots get bigger, and more develop until a ring-shaped blind spot is present.[dbproject.mn.org]
  • However, a loss of hearing is usually evident when the child reaches their teen years and night vision also begins to present as an issue.[news-medical.net]

  • The Audiologist's Role in Review The diagnosis of significant hearing loss in a child can so dominate our attention as audiologists that we may overlook other disabling conditions.[asha.org]
  • If one reviews any public health and prevention literature on chronic disability, one notes that education and preparation for self care are absolute keys to success.[nationaldb.org]

  • In-Depth Information The Monarch Initiative brings together data about this condition from humans and other species to help physicians and biomedical researchers.[rarediseases.info.nih.gov]
  • […] estimated that the R245X mutation originated in the Ashkenazi population 14 generations, or approximately 350 years, ago. 22 Discussion One of the earliest written descriptions of the clinical features of the Usher syndrome was published in 1861 by a physician[nejm.org]
  • The physicians who saw these children felt that some of the vestibular issues would go away because they were premature. Since they thought the etiology of the hearing loss was Connexin 26, no one ever mentioned Usher or looked into it.[audiologyonline.com]
Esotropia
  • Orthoptic examination revealed left esotropia of 30 prism diopters. Alternate cover test showed alternate esotropia. Secondary deviation was greater than primary deviation.[healio.com]
Dysacusis
  • Other names for Usher syndrome include Hallgren syndrome, Usher-Hallgren syndrome, retinitis pigmentosa-dysacusis syndrome, and dystrophia retinae dysacusis syndrome. Usher syndrome is incurable at present.[disabled-world.com]

Behavior Problem
  • About 1 in 4 children have behavioral problems or psychosocial difficulties. Genetics Type I Usher syndrome is an autosomal recessive genetically heterogeneous disorder as mutations in at least 8 genes produce a similar disease.[disorders.eyes.arizona.edu]

Treatment

  • Back to top What treatments are available? While there are no treatments for Usher syndrome, intensive research is underway to discover the causes of and treatments for all types of the disease.[blindness.org]
  • Research using mouse models will help determine the function of Usher genes and inform potential treatments.[nidcd.nih.gov]
  • Information about a therapy, service, product or treatment does not in any way endorse or support such therapy, service, product or treatment and is not intended to replace advice from your doctor or other registered health professional.[betterhealth.vic.gov.au]
  • Currently there is no cure or effective treatment for Usher Syndrome Type 1 Evaluation for severity of condition includes: Auditory, Vestibular function and Visual.[mazornet.com]

Prognosis

  • 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]
  • What is the prognosis for a person with Usher Syndrome Type 1F? Usher syndrome type 1F causes severe hearing and vision impairment, however it does not affect one’s lifespan or intelligence.[jscreen.org]
  • But they struggled mightily with the added prognosis of Usher Syndrome Type 1: foremost, vision loss due to retinitis pigmentosa, or RP, a degenerative condition of the retina which begins in early adolescence and leads to blindness.[southcoasttoday.com]
  • Again, the prognosis of eventual blindness comes as a shock.[asha.org]
  • […] third decade) Visual field loss Appears mid-childhood Less than 20 degrees probable by mid 20's Slower, but legal blindness probable at some point Central visual acuity Progressive loss with early development of cataracts Less severe but great variation Prognosis[tsbvi.edu]

Etiology

  • Etiology So far, mutations in five genes ( MYO7A , USH1C , CDH23 , PCDH15 , USH1G ) and one locus ( USH1E ) have been implicated in US type 1.[orpha.net]
  • 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

  • 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]
