Usher Syndrome, Type Iiib; Ush3b

Description

Usher syndrome type III is characterized by postlingual, progressive hearing loss, variable vestibular dysfunction, and onset of retinitis pigmentosa symptoms, including nyctalopia, constriction of the visual fields, and loss of central visual acuity, usually by the second decade of life (Karjalainen et al., 1985; Pakarinen et al., 1995).For a discussion of genetic heterogeneity of type III Usher syndrome, see USH3A (OMIM ).
