Tietz syndrome, also called Tietz albinism-deafness syndrome or albinism and deafness of Tietz,^[1] is an autosomal dominant^[2] congenital disorder characterized by deafness and leucism.^[3] It is caused by a mutation in the microphthalmia-associated transcription factor (MITF) gene.^[2]^[4] Tietz syndrome was first described in 1923.^[5]

[edit] Cause and Genetics

Tietz syndrome has an autosomal dominant pattern of inheritance.

Tietz syndrome is caused by mutations in the MITF gene, located on human chromosome 3p14.1-p12.3.^[2]^[4]^[6] It is inherited in an autosomal dominant manner.^[2] This indicates that the defective gene responsible for a disorder is located on an autosome (chromosome 3 is an autosome), and only one copy of the defective gene is sufficient to cause the disorder, when inherited from a parent who has the disorder.
