Tietz syndrome (tēts'), [MIM*103500] autosomal dominant inheritance of albinism and deafness caused at least in some subsets of families by a mutation of the microophthalmia transcription factor gene on chromosome 3p.Tietz syndrome An autosomal dominant disorder (OMIM:103500) characterised by generalised hypopigmentation and profound congenital deafness.
