Introduction: Iodide transport in the thyroid is crucial for thyroid hormone synthesis. A homozygous loss-of-function mutation in the SLC26A4gene coding an iodide transporter located at the apical side in the thyroid follicular cells causes Pendred syndrome accompanied with goitrous congenital hypothyroidism (CH) and sensorineural deafness. However, about half of patients with Pendred syndrome demonstrate normal thyroid function. This indicates anothe...
