Progressive hearing loss has been reported in people with Waardenburg syndrome type 2. Although some studies reporting progressive hearing loss in people with Waardenburg syndrome did not clearly describe the subtype of Waardenburg syndrome present, it is believed that progressive hearing loss is limited to those with type 2. We are not aware of data describing the proportion of people with type 2 who have progressive versus non-progressive hearing loss.
