CDH23 (Cadherin-related 23): CDH23 encodes a protein that is part of the cadherin superfamily, known for its role in cell-cell adhesion. CDH23 is particularly important for the structure and function of the hair cells in the inner ear, which are responsible for hearing and balance. Mutations in CDH23 are associated with Usher syndrome and non-syndromic hearing loss, highlighting its significance for sensory function. Research on CDH23 focuses on understanding hearing mechanisms and developing treatments for related hearing impairments.
