Pendred syndrome or Pendred disease is a genetic disorder leading to congenital bilateral (both sides) sensorineural hearing loss and goitre with occasional hypothyroidism (decreased thyroid gland function). There is no specific treatment, other than supportive measures for the hearing loss and thyroid hormone supplementation in case of hypothyroidism. It is named Dr Vaughan Pendred (1869 1946), the English doctor who first described the condition in an Irish family living in Durham in 1896. It accounts for 7.5% of all cases of congenital deafness.
