DFNA49, a novel locus for autosomal dominant nonsyndromic hearing loss, maps proximal to DFNA7/DFNM1 region on chromosome 1q21-q23 (J Med Genet 2003;40:832–836).

Owing to a fault in the production process an error was introduced to figure 2 of this paper. The last gene at the bottom of the figure should correspond to CASQ1, and not to ATP1A2, which is mapped just above it. We apologise for this error.
