| Disease ID | Source | Name | Description |
| 601067 | OMIM | Usher syndrome 1D/F (USH1DF) | USH1DF patients are heterozygous for mutations in CDH23 and PCDH15, indicating a digenic inheritance pattern. The disease is caused by variants affecting distinct genetic loci, including the gene represented in this entry. |
| 602083 | OMIM | Usher syndrome 1F (USH1F) | USH 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. The disease is caused by variants affecting the gene represented in this entry. |
| 609533 | OMIM | Deafness, autosomal recessive, 23 (DFNB23) | A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. The disease is caused by variants affecting the gene represented in this entry. |
| 276900 | OMIM | Usher syndrome 1B (USH1B) | USH 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. |
