Tietz syndrome(TADS)

MedGen UID:
98213
Concept ID:
C0391816
Disease or Syndrome
Synonyms: Albinism-deafness of Tietz; Hypopigmentation/deafness of Tietz; TADS; Tietz albinism-deafness syndrome
SNOMED CT: Albinism-deafness syndrome of Tietz (403805009)
Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

Tietz albinism-deafness syndrome (TADS) is characterized by generalized pigment loss and congenital complete sensorineural hearing loss (summary by Izumi et al., 2008). [from OMIM]

Additional description

From MedlinePlus Genetics
Tietz syndrome is a disorder characterized by profound hearing loss from birth, fair skin, and light-colored hair. The hearing loss in affected individuals is caused by abnormalities of the inner ear (sensorineural hearing loss) and is present from birth. Although people with Tietz syndrome are born with white hair and very pale skin, their hair color often darkens over time to blond or red. The skin of affected individuals, which sunburns very easily, may tan slightly or develop reddish freckles with limited sun exposure; however, their skin and hair color remain lighter than those of other members of their family.

Tietz syndrome also affects the eyes. The colored part of the eye (the iris) in affected individuals is blue, and specialized cells in the eye called retinal pigment epithelial cells lack their normal pigment. The retinal pigment epithelium nourishes the retina, the part of the eye that detects light and color. The changes to the retinal pigment epithelium are generally detectable only by an eye examination; it is unclear whether the changes affect vision.  https://medlineplus.gov/genetics/condition/tietz-syndrome

Clinical features

From HPO
Congenital sensorineural hearing impairment
MedGen UID:
356101
Concept ID:
C1865866
Disease or Syndrome
A type of hearing impairment caused by an abnormal functionality of the cochlear nerve with congenital onset.
White eyelashes
MedGen UID:
332275
Concept ID:
C1836736
Finding
White color (lack of pigmentation) of the eyelashes.
White eyebrow
MedGen UID:
373165
Concept ID:
C1836737
Finding
White color (lack of pigmentation) of the eyebrow.
Generalized hypopigmentation
MedGen UID:
340426
Concept ID:
C1849923
Finding
Hypopigmentation of the fundus
MedGen UID:
101805
Concept ID:
C0151891
Disease or Syndrome
Reduced pigmentation of the fundus, typically generalized. Fundoscopy may reveal a low level pigment in both RPE and choroid with clear visibility of choroidal vessels (pale/albinoid) or low pigment level in the RPE with deep pigment in choroid so that visible choroidal vessels are separated by deeply pigmented zones (tesselated/tigroid).
Heterochromia iridis
MedGen UID:
98395
Concept ID:
C0423318
Finding
Heterochromia iridis is a difference in the color of the iris in the two eyes.
Blue irides
MedGen UID:
108297
Concept ID:
C0578626
Finding
A markedly blue coloration of the iris.
