Vestibular Deficit in Patients with Waardenburg Syndrome.

: Waardenburg syndrome (WS) is a genetic disorder characterized by sensorineural hearing loss (SNHL) and pigmentation anomalies. While hearing impairment is a well-established feature of WS, vestibular dysfunction is also reported. This study aimed to investigate vestibular deficits in pediatric WS patients with SNHL, correlating these findings with molecular, audiometric, and radiological data to establish distinct phenotypic profiles for each WS subtype and associated pathogenic variants.
