Autosomal recessive nonsyndromic sensorineural deafness segregating in a large consanguineous Indian family was mapped to chromosome 11p14-p15.1 defining a new locus, DFNB18. A maximum lod score of 4.4 at O = 0 was obtained for the polymorphic microsatellite marker D11S1888. Haplotype analysis localizes this gene between markers D11S1307 and D11S2368, which is approximately 1.6 cM and encompasses the region of Usher syndrome type 1C (USHIC). We postulate that DFNB18 and USHIC are allelic variants of the same gene.
