How the Genetics of Deafness Illuminates Auditory Physiology

Although the basic principles underlying the function of the peripheral auditory system have been known for many years, the molecules required for hearing have hitherto remained elusive. Genetic approaches have recently provided unparalleled molecular insight into how the hair bundle, the hair cell's mechanosensory organelle, forms and functions. We discuss how the proteins encoded by the Usher syndrome type 1 genes form molecular complexes...
