Cloning genes for non-syndromal hearing impairment

Over 45 genes that cause autosomal non-syndromic hearing impairment (NSHI) have been localized and many more are predicted to exist. To clone these genes, a number of different strategies can be used. This paper focuses on four general approaches: functional cloning, positional cloning, position-dependent candidate gene cloning, and position-independent candidate gene cloning.
