The gene for Pendred's syndrome is found on chromosome 7 and codes for the protein Pendrin which was predicted to be a sulphate transporter.

  • the novel gene SLC26A4 (PDS) coding for a protein 'pendrin' initially thought to function as a sulfate transporter is responsible for the syndrome (2)
    • subsequent studies excluded sulfate transport activity and suggested that the protein functions as a membrane-bound chloride-iodine transporter
