Popis: Pendred syndrome is an autosomal recessive disorder characterized by congenital sensorineural deafness, goitre and defective iodide organification. Congenital and profound hearing loss is the hallmark of the syndrome, while goitre and thyroid dysfunction are highly variable even within the same family. Clinical features are due to altered formation of pendrin, a chloride/iodide transporter protein expressed in the inner ear, thyroid gland and kidney. A novel substitution was found in exon 7 of the pendrin encoding gene (SLC26A4) that leads to a stop codon, S314X. The new variation was found in compound heterozygosity with L445W mutation in a hearing impaired patient with bilateral Mondini's dysplasia and goitre.
