Waardenburg Syndrome, Type 1; Ws1

Description

Waardenburg syndrome type 1 is an autosomal dominant auditory-pigmentary syndrome characterized by pigmentary abnormalities of the hair, skin, and eyes; congenital sensorineural hearing loss; and 'dystopia canthorum,' the lateral displacement of the ocular inner canthi (reviews by Read and Newton, 1997, Tamayo et al., 2008, and Pingault et al., 2010). Clinical Variability of Waardenburg Syndrome Types 1-4Waardenburg syndrome is an auditory-pigmentary syndrome characterized by pigmentary abnormalities of the hair, including a white forelock and premature graying; pigmentary changes of the iris, such as heterochromia irides and brilliant blue eyes; and congenital sensorineural hearing loss. Waardenburg syndrome has been classified into 4 main phenotypes. WS type 1 is distinguished by the presence of dystopia canthorum. WS type 2 (WS2; see {193510}) is distinguished from type 1 by the absence of dystopia canthorum. WS type 3 (WS3 ) has dystopia canthorum and upper limb abnormalities. WS type 4 (WS4; see {277580}), also known as Waardenburg-Shah syndrome, has the additional feature of Hirschsprung disease (reviews by Read and Newton, 1997 and Tamayo et al., 2008). Genetic Heterogeneity of All Types of Waardenburg SyndromeWaardenburg syndrome is genetically heterogeneous. WS1 and WS3 are both caused by mutation in the PAX3 gene. See WS2A (OMIM ) for a discussion of genetic heterogeneity of WS type 2, and WS4A (OMIM ) for a discussion of genetic heterogeneity of WS type 4.
