Hearing loss is the most common sensory deficit in humans. Genetic deafness can be one clinical finding in a collection of symptoms that characterize a specific disease or it can be the sole consequence of a single gene mutation. Different mutations in the same gene can result in different forms of deafness or different inheritance patterns. This article begins with an overview of incidence of hearing loss in the general population. It then discusses syndromic versus non-syndromic hearing loss. It also reveals hearing loss caused by mitochondric mutation. Furthermore, it explains mechanisms to find the deafness genes in humans, giving examples of some deafness genes and functional groups, and what has been learned from them. Following this, it deals with the procedure of genetic testing for deafness. Finally, it reveals the difference between Deaf culture and being deaf, throwing light on the need to develop sensitivity to the Deaf culture.
