Welcome to the Hereditary Hearing Loss Homepage

The Hereditary Hearing Loss Homepage aims to give an up-to-date overview of the genetics of hereditary hearing impairment for researchers and clinicians working in the field.

This site lists data and links for all known gene localizations and identifications for monogenic nonsyndromic hearing impairment.

Summary of genes identified to date:

Total non-syndromic hearing loss genes identified to date: 112
Autosomal dominant non-syndromic hearing loss genes: 45
Autosomal recessive non-syndromic hearing loss genes: 71
X-linked non-syndromic hearing loss genes: 5

Note that some genes cause recessive AND dominant hearing loss. The numbers given above are unique genes identified to date.
