UniProtKB/Swiss-Prot : ⁷³ Usher syndrome 4: A form of Usher syndrome, 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 different types of Usher syndrome. USH4 is characterized by late onset of retinitis pigmentosa and usually late-onset of progressive sensorineural hearing loss without vestibular involvement. USH4 inheritance is autosomal recessive.

MalaCards based summary : Usher Syndrome, Type Iv, also known as usher syndrome, type 4, is related to usher syndrome, type i and retinitis pigmentosa. An important gene associated with Usher Syndrome, Type Iv is ARSG (Arylsulfatase G). Affiliated tissues include bone, and related phenotypes are progressive sensorineural hearing impairment and retinal atrophy

OMIM® : ⁵⁷ An atypical form of Usher syndrome, here designated type IV, is an autosomal recessive disorder characterized by late onset of retinitis pigmentosa and usually late-onset of progressive sensorineural hearing loss without vestibular involvement (summary by Khateb et al., 2018).
