Involvement in diseasei

Usher syndrome 1G2 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionUSH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH1 is characterized by profound congenital sensorineural deafness, absent vestibular function and prepubertal onset of progressive retinitis pigmentosa leading to blindness.

VAR_060468

The first cases with non-syndromic sensorineural hearing loss based on mutations in USH1G. The hearing loss has an onset during early childhood, is progressive, and has a downsloping audiogram configuration. Ophthalmic and vestibular abnormalities are absent.
