✦ Synopsis


Pendred syndrome is an autosomal-recessive disorder characterized by congenital sensorineural hearing loss combined with goiter. This disorder may account for up to 10% of cases of hereditary deafness. The disease gene ( PDS/SLC26A4) has been mapped to chromosome 7q22-q31 and encodes a chloride-iodide transport protein. Mutations in this gene are also a cause of non-syndromic autosomal recessive hearing impairment (DFNB4). We have analyzed the PDS/SLC26A4 gene in Spanish and Italian families and we have detected five new mutations (X871M, T132I, IVS1-2A>G, Y556H and 406del5).
