Hearing Loss and Thyroid Disease (Pendred Syndrome)

Pendred syndrome is a genetic condition leading to early sensorineural hearing loss and variable development of a goiter. Goiter is present in approximately 75% of individuals with Pendred syndrome. Approximately 40% develop goiter in late childhood or early puberty, with the remainder presenting in early adulthood. Genetic screening for the Pendred syndrome gene (PDS, SLC26A4) is available on a clinical basis. Despite the presence of goiter as one of the defining clinical features of this disease, only 50% of individuals with Pendred syndrome have hypothyroidism, while the remaining 50% are euthyroid. Most children with Pendred syndrome have normal growth and development. Children with Pendred syndrome should be evaluated by a pediatric otolaryngologist, particularly because of the association with inner ear anomalies (e.g., enlarged vestibular aqueduct). It is estimated that 5% of all children born with hearing loss may have Pendred syndrome. The underlying defect appears to bean abnormality in iodine trapping. Consultation with a geneticist or genetic counsellor is recommended to coordinate testing for Pendred syndrome.
