Linkage of a gene for dominant non-syndromic deafness to chromosome 19

Abstract

Inherited hearing impairment can occur either in the presence of other clinical features (syndromic hearing loss, SHL) or in isolation (non-syndromic hearing loss, NSHL). The latter is more common and is highly heterogeneous. To date, six NSHL loci have been mapped. We report the identification of a seventh locus (DFNA4) on chromosome 19q13 and suggest DM kinase as a possible candidate gene.
