• Hearing Impairment

  Patients with type 2 disease generally are hearing impaired but have no balance problems. All patients develop eye problems that cause difficulty seeing in the dark. [clinicaltrials.gov]

  Abstract Usher syndrome (USH) is an autosomal recessive disorder associated with sensorineural hearing impairment and progressive visual loss attributable to retinitis pigmentosa. This syndrome is both clinically and genetically heterogeneous. [ncbi.nlm.nih.gov]

  (NH), children with hearing impairment and hearing aids (HI+HA), and children with other types of deafness and CI (other CI). [diva-portal.org]

  Usher Syndrome is the most common genetic cause of deaf-blindness in adults and affects 3-6% of children born with hearing impairment(Kremer et al., 2006). [ushersyndrome.wordpress.com]

• Peripheral Vision Loss

  RP typically begins with night blindness and peripheral vision loss. These symptoms usually get worse with age. Delayed gross motor milestones are common in cases with vestibular abnormalities with early onset. [fulgentgenetics.com]

  Individuals with Usher Syndrome have hearing loss and vision loss. [evolvegene.com]

  Over time, these blind spots gradually enlarge and constrict inwards towards the centre of their vision, eventually leaving a small area of central vision to see out of, like seeing through a tunnel (tunnel vision) Peripheral vision loss Tunnel vision [gene.vision]

  In some cases, hearing loss may worsen over time. Onset of night blindness occurs during the late teens or early twenties. Peripheral vision loss is ongoing, but central vision is usually retained into adulthood. [rarediseases.org]

• Retinal Pigmentation

  On fluorescein angiography, both eyes showed diffuse hyperfluorescence due to pigment epithelial atrophy together with hypofluorescence, corresponding to bone spicule pigment clumping. These findings were consistent with retinitis pigmentosa. [jamanetwork.com]

  Additionally, Myosin VIIa, coded by MYO7a, has a direct involvement in transporting melanosomes and phagosomes in retinal pigment epithelium (RPE) correctly and translocating RPE65 for visual pigment regeneration. [eyewiki.aao.org]

Genetic testing can help clinicians confirm the diagnosis and specific etiology of Usher syndrome. This information helps clinicians provide more personalized care and prepare patients for the onset of symptoms. [fulgentgenetics.com]

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]

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]
