Tietz Albinism-Deafness syndrome (TADS)

What is Tietz Albinism-Deafness syndrome?

Tietz Albinism syndrome is a rare congenital syndrome that presents with hearing loss, fair skin, and very light-colored hair.

This syndrome is also known as:
Albinism-deafness; Albinism-deafness of Tietz; Hypopigmentation/deafness of Tietz; Tietz syndrome

What gene changes cause this syndrome?

Changes in the MITF gene are responsible for causing the syndrome.

The syndrome is inherited in an autosomal dominant pattern.

What are the main symptoms of Tietz Albinism-Deafness syndrome?

  • Hearing loss is one of the main symptoms of the syndrome. It is caused by inner ear abnormalities and is congenital and thus present from birth.
  • Infants with the syndrome are born with very fair skin and white hair including white eyelashes and white eyebrows, both of which are defining characteristics of the syndrome. They will also have blue eyes
  • Common visual issues include photophobia (sensitivity to light) and possible nystagmus (involuntary eye movements), often related to reduced eye pigmentation.

Possible clinical traits/features:
Aplasia/Hypoplasia of the eyebrow, Abnormal anterior chamber morphology, Blue irides, Bilateral sensorineural hearing impairment, Hypopigmentation of the fundus, Hypopigmentation of hair, Generalized hypopigmentation, Heterochromia iridis, White eyebrow, White eyelashes, Autosomal dominant inheritance, Congenital sensorineural hearing impairment.

How is it diagnosed?

To find out if someone has a diagnosis of Tietz Albinism-Deafness syndrome, it is important to have a consultation and evaluation with a clinical genetic specialist.  Specialists may also suggest specific genetic testing or other types of tests to help reach a diagnosis.  FDNA’s AI technology can help speed up the diagnostic process by analyzing facial features and other health information.

Yunis-Varon syndrome (YVS)

It is a rare genetic disease that affects multiple systems of the body. Its main symptoms affect the skeletal and nervous systems, as well as ectodermal tissue (hair and teeth). Since 1980 just 25 cases from 19 families have been diagnosed and recorded. This syndrome is also known as: Cleidocranial Dysplasia With Micrognathia, Absent Thumbs, And Distal Aphalangia

Xia-Gibbs syndrome (XIGIS)

It is a rare genetic syndrome associated mainly with intellectual disability. This syndrome is also known as: Mental Retardation, Autosomal Dominant 25; Mrd25 Changes in the AHDC1 gene are responsible for causing the syndrome. It is inherited in an autosomal dominant pattern, although all cases of the syndrome recorded so far have been the result of de novo or new mutations in the gene. In the case of autosomal dominant inheritance just one parent is the carrier of the gene mutation, and they have a 50% chance of passing it onto each of their children. Syndromes inherited in an autosomal dominant inheritance are caused by just one copy of the gene mutation. In some cases, a genetic syndrome may be the result of a de-novo mutation and the first case in a family. In this case, this is a new gene mutation which occurs during the reproductive process.
