Tietz syndrome is an autosomal dominant syndrome of hypopigmentation and deafness. A missense mutation has been found in the basic region of the MITF (microphthalmia associated transcription factor) gene. Mutations in other regions of this gene have been found to produce Waardenburg syndrome type 2 (WS2) [DS:H00169], which also includes pigmentary changes and hearing loss, but in contrast to Tietz syndrome, depigmentation is patchy and hearing loss is variable in WS2.
