Affected individuals present with congenital deafness and a highly variable degree of retinal degeneration. Using a positional candidate approach, we identified a new member of the cadherin gene superfamily, CDH23. [ncbi.nlm.nih.gov]

In the present study, we carried out a systematic mutation screening of these genes in USH1 patients from USA and from UK. [wwww.unboundmedicine.com]

Most of these mutations disrupt protein production, resulting in an abnormally small, nonfunctional version of cadherin 23 or preventing the production of any of this protein. Less frequently, mutations change single amino acids in cadherin 23. [ghr.nlm.nih.gov]
