Usher Syndrome, Type Iic; Ush2c

Description

Usher syndrome is a clinically and genetically heterogeneous autosomal recessive disorder characterized by sensorineural hearing deficiencies at birth and later development of progressive retinitis pigmentosa (RP). It is the most frequent cause of combined deafness and blindness in adults and affects 3 to 6% of children born with hearing impairment. In brief, patients with Usher syndrome type II have mild hearing impairment with normal vestibular responses. Type II is the most common of the 3 Usher syndromes (Eudy et al., 1998). See {276900} for clinical characterization of Usher syndrome types I, II, and III.For a discussion of genetic heterogeneity of Usher syndrome type II, see USH2A (OMIM ).
