An inherited form of deafness accompanied by a characteristic white forelock of hair and multiple colours within the irises of the eyes. It is inherited as an autosomal dominant disease, i.e. the children of an affected parent have a 50% chance of inheriting the disorder, although severity is variable. The gene responsible has been identified. P. J. Waardenburg (1886–1979), Dutch ophthalmologist
