Waardenburg syndrome type 2A

Waardenburg syndrome type 2 is an autosomal dominant auditory-pigmentary syndrome characterized by pigmentary abnormalities of the hair, skin, and eyes; congenital sensorineural hearing loss; and the absence of 'dystopia canthorum,' the lateral displacement of the ocular inner canthi, which is seen in some other forms of WS (reviews by Read and Newton, 1997 and Pingault et al., 2010). Waardenburg syndrome type 2A is caused by mutation in the MITF gene (156845). Clinical Variability of Waardenburg Syndrome Types 1-4 Waardenburg syndrome has been classified into 4 main phenotypes. Type I Waardenburg syndrome (WS1; 193500) is characterized by pigmentary abnormalities of the hair, including a white forelock and premature graying; pigmentary changes of the iris, such as heterochromia iridis and brilliant blue eyes; congenital sensorineural hearing loss; and 'dystopia canthorum.' WS type II (WS2) is distinguished from type I by the absence of dystopia canthorum. WS type III (WS3; 148820) has dystopia canthorum and is distinguished by the presence of upper limb abnormalities. WS type IV (WS4; 277580), also known as Waardenburg-Shah syndrome, has the additional feature of Hirschsprung disease (reviews by Read and Newton, 1997 and Pingault et al., 2010). Genetic Heterogeneity of Waardenburg Syndrome Type 2 Waardenburg syndrome type 2 is a genetically heterogeneous disorder. WS2B (600193) has been mapped to chromosome 1p, WS2C (606662) has been mapped to chromosome 8p23, WSD (608890) is caused by mutation in the SNAI2 gene (602150) on chromosome 8q11, and WS2E (611584) is caused by mutation in the SOX10 gene (602229) on chromosome 22q13. [from OMIM]

Waardenburg syndrome type 2E

Waardenburg syndrome type 2 is an auditory-pigmentary syndrome characterized by pigmentary abnormalities of the hair, skin, and eyes; congenital sensorineural hearing loss; and the absence of 'dystopia canthorum,' the lateral displacement of the inner canthus of each eye, which is seen in some other forms of WS (review by Read and Newton, 1997). Individuals with WS type 2E, which is caused by mutation in the SOX10 gene (602229), may have neurologic abnormalities, including mental impairment, myelination defects, and ataxia. Waardenburg syndrome type 2 is genetically heterogeneous (see WS2A; 193510). For a description of other clinical variants of Waardenburg syndrome, see WS1 (193500), WS3 (148820), and WS4 (277580). [from OMIM]
