Waardenburg syndrome has multiple different types with some variations in symptoms, and symptoms can vary among those with the same type. The two features consistent across all types of Waardenburg syndrome are some degree of congenital sensorineural hearing loss and some degree of pigmentation deficiencies, most consistently in the eyes.

Waardenburg syndrome type 1 is a congenital disorder that caused by a mutation in the PAX3 gene that results in abnormal development in the neural crest during early development. Type 1 results in early graying and white forelock and a notable distance between the eyes, noted as dystopia canthorum. Common symptoms of the disease also includes ...
Waardenburg syndrome type 4A is an extremely rare congenital disorder caused by a mutation in an endothelin receptor gene. It results in common Waardenburg syndrome symptoms such as abnormal hair and skin pigmentation and heterochromia , but also present with symptoms of Hirschsprung's disease .
She did not allow her surgeon to alter any of her Waardenburg syndrome features. [4] Sanjati shared the healing process on her YouTube channel. [citation needed] In April 2020, Sanjati retired her YouTube channel. On January 25, 2021, Sanjati posted a video on her YouTube channel announcing she is changing the topic of her content.
The disorder may occur by itself or in association with other genetic disorders such as Down syndrome or Waardenburg syndrome. [1] [2] About half of isolated cases are linked to a specific genetic mutation, and about 20% occur within families. [1] Some of these occur in an autosomal dominant manner. [1] The cause of the remaining cases is ...
There is nevertheless great variation in the degree and pattern of presentation, even within affected families. In some cases, piebaldism occurs together with severe developmental problems, as in Waardenburg syndrome and Hirschsprung's disease. Piebaldism has been documented to occur in all races, and is found in nearly every species of mammal.
Waardenburg syndrome type 2D, a subtype of the Waardenburg syndrome, is a rare congenital disorder caused by a mutation in the SLUG (SNAI2) gene. It is characterized by the lack of pigmentation in the skin, hair, and eyes as well as the abnormalities in the outer wall of the cochlea .
Waardenburg syndrome is a rare genetic disorder most often characterized by varying degrees of deafness, minor defects in structures arising from the neural crest, and pigmentation anomalies. [ 2 ] In 1913, Jan van der Hoeve observed and described a lateral position of the lacrimal points and shortened eyelid slit in identical deaf mute twins ...
