Pendred syndrome: Sensitivity and Specificity

Introduction:

  • Most common syndromic form of hereditary SNHL
  • AR
  • Associated thyroid goiter develops in 2nd decade of life - usually euthyroid
  • Hearing loss is usually congenital - severe to profound, bilateral and pre-lingual
  • Most cases result from mutations in SLC26A4 gene that encodes an anion transporter known as pendrin that is expressed in the inner ear, thyroid, and kidney
  • Radiologic studies always show a temporal bone anomaly, either dilated vestibular aqueducts or Mondini dysplasia
  • [Edit Diagnosis] [Merge dx] [Add prevalence]

    Tags: None. Tag this Diagnosis.
