Long-term hearing threshold-on-age follow-up data, including non-linear regression analysis, are given for 12 consecutive Pendred patients. The clinical diagnosis of Pendred's syndrome was confirmed by a mutation analysis of the PDS gene in 11 out of the 11 cases tested. Recent imaging of the temporal bones in seven out of these 12 patients showed widened vestibular aqueducts in each case. The diagnostic perchlorate test was negative in one patient, but this test was positive in her affected sister. Mutation analysis of the PDS gene in these patients confirmed that Pendred's syndrome is a monogenetic disorder. Progressive sensorineural hearing loss and widened vestibular aqueducts are characteristic features of Pendred's syndrome, which provides the opportunity to diagnose Pendred's syndrome clinically in the first few years of life, as has recently been suggested in a case report (Cremers et al., Progressive sensorineural hearing loss and a widend vestibular aqueduct in Pendred syndrome, Arch. Otolaryngol. 124 (1998) 501-505). Mutation analysis of the involved gene can be used to confirm the clinical diagnosis.
