Dominant and recessive deafness caused by mutations of a novel gene, TMC1, required for cochlear hair-cell function
Positional cloning of hereditary deafness genes is a direct approach to identify molecules and mechanisms underlying auditory function. Here we report a locus for dominant deafness, DFNA36, which… Expand

The Tip-Link Antigen, a Protein Associated with the Transduction Complex of Sensory Hair Cells, Is Protocadherin-15
Sound and acceleration are detected by hair bundles, mechanosensory structures located at the apical pole of hair cells in the inner ear. The different elements of the hair bundle, the stereocilia… Expand

Myosin-XVa is required for tip localization of whirlin and differential elongation of hair-cell stereocilia
Stereocilia are microvilli-derived mechanosensory organelles that are arranged in rows of graded heights on the apical surface of inner-ear hair cells. The 'staircase'-like architecture of… Expand

PCDH15 is expressed in the neurosensory epithelium of the eye and ear and mutant alleles are responsible for both USH1F and DFNB23.
Recessive splice site and nonsense mutations of PCDH15, encoding protocadherin 15, are known to cause deafness and retinitis pigmentosa in Usher syndrome type 1F (USH1F). Here we report that… Expand

Tricellulin is a tight-junction protein necessary for hearing.
The inner ear has fluid-filled compartments of different ionic compositions, including the endolymphatic and perilymphatic spaces of the organ of Corti; the separation from one another by epithelial… Expand

Spatiotemporal pattern and isoforms of cadherin 23 in wild type and waltzer mice during inner ear hair cell development.
Mutant alleles of the gene encoding cadherin 23 are associated with Usher syndrome type 1 (USH1D), isolated deafness (DFNB12) in humans, and deafness and circling behavior in waltzer (v) mice.… Expand

Nonsyndromic recessive deafness DFNB18 and Usher syndrome type IC are allelic mutations of USHIC
Abstract. Human chromosome 11 harbors two Usher type I loci, USHIB and USHIC, which encode myosin VIIA and harmonin, respectively. The USHIC locus overlaps the reported critical interval for… Expand

Targeted capture and next-generation sequencing identifies C9orf75, encoding taperin, as the mutated gene in nonsyndromic deafness DFNB79.
Targeted genome capture combined with next-generation sequencing was used to analyze 2.9 Mb of the DFNB79 interval on chromosome 9q34.3, which includes 108 candidate genes. Genomic DNA from an… Expand

Mutations of MYO6 are associated with recessive deafness, DFNB37.
Cosegregation of profound, congenital deafness with markers on chromosome 6q13 in three Pakistani families defines a new recessive deafness locus, DFNB37. Haplotype analyses reveal a 6-cM linkage… Expand

Loss-of-function mutations of ILDR1 cause autosomal-recessive hearing impairment DFNB42.
By using homozygosity mapping in a consanguineous Pakistani family, we detected linkage of nonsyndromic hearing loss to a 7.6 Mb region on chromosome 3q13.31-q21.1 within the previously reported… Expand
