Pendred syndrome is a disorder typically associated with hearing loss and a thyroid condition called goiter. Other abnormalities of the inner ear are also common in Pendred syndrome. Some affected individuals have problems with balance caused by dysfunction of the part of the inner ear that helps maintain the body's balance and orientation (the vestibular system). Additionally, a structure called the vestibular aqueduct is unusually large in people with Pendred syndrome. Mutations in the SLC26A4 gene cause about half of all familial cases of Pendred syndrome. In some cases, the cause of Pendred syndrome is unknown. Researchers are looking for additional genetic changes that may underlie the condition. Pendred syndrome is inherited in an autosomal recessive pattern.[1]
