22. The phenotype associated with the I109N COCH mutation is largely similar to that associated with the I109T, P51S, G87W, and G88E mutation carriers. However, subtle differences seem to exist in terms of age of onset and rate of progression. PMID: 21774451
23. All affected family members with a COCH mutation in the vWFA2 domain shared sensorineural hearing loss with full penetrance starting between the second and fifth decade of life. PMID: 17944208
24. The onset of the hearing loss, in the 2nd or 3rd decade of life, is earlier than in most DFNA9 families. The progression of hearing loss and vestibular dysfunction in the American family is typical of other DFNA9 families with mutations in this domain. PMID: 21046548
