Objectives: To identify mutations in the SLC26A4 gene
in individuals with nonsyndromic hearing loss and en-
larged vestibular aqueduct, to design a predicted model
of the pendrin protein, and to characterize novel muta-
tions by means of localization in mammalian cells and
effect of the mutation on the predicted model.
Design: Validation of the mutation by its exclusion in
more than 300 individuals with normal hearing.
Setting: A laboratory of genetics of hearing loss re-
search, clinical genetics laboratories, an otolaryngology
department at Tel Aviv University, and medical centers
Patients: A patient with nonsyndromic hearing loss and
enlarged vestibular aqueduct, 203 deaf probands, and 310
controls with normal hearing.
