A PAX3 polymorphism (T315K) in a family exhibiting Waardenburg Syndrome type 2.
Waardenburg Syndrome (WS) is an autosomal-dominant disorder phenotypically characterized by sensorineural hearing loss and pigmentary disturbances. Presence of dystopia canthorum is indicative of WS type 1 and results from defects in the PAX3 gene, whereas normally located medial canthi is characteristic of type 2 WS (WS2) and is associated with defects in the microphthalmia-associated transcription factor (MIFT) gene. Here a neutral polymorphism is reported in the PAX3 gene (T315K) in a family with WS2.
