Overview While acquired deafness associated with age or noise exposure is more common than genetic deafness by roughly two orders of magnitude, congenital deafness occurs in 1 out of every 1,000 to 2,000 births. Autosomal recessive inheritance is the most common form, accounting for more than 75% of all congenital deafness.

Pendred syndrome is a autosomal recessive disease, classically characterized by congenital sensorineural hearing loss, goiter and iodine organification defect. The chromosomal region, 7q31(PDS gene), was identified as this syndrome locus in 1998.

There is no agreement in the literature as to the most frequent abnormality in the ear in patients with Pendred syndrome. Cochlear defect described as "Mondini malformation" was cited as an almost constant finding in a radiologic study performed with conventional tomography ( 6 ).

I also have found two journal articles that you might find very informative. They are "The Enlarged Vestibular Aqueduct Syndrome (EVA Syndrome)" Article found in the ENT Journal for their November 1993 issue.

The Clinical Diagnostics Service of the Molecular Otolaryngology Research Laboratories is a Joint Commission-approved CLIA-accredited diagnostic laboratory that offers mutation screening of several genes. DFNB4 (OMIM# 600791 ) and Pendred syndrome (OMIM#: 274600 ) DFNB4 Baldwin and colleagues reported linkage of a family with recessive, nonsyndromic deafness to chromosome 7q31 in 1995 and designated this locus as DFNB4.

Background: Enlarged Vestibular Aqueduct Syndrome (MIM 603545) is the most common form of congenital inner ear abnormality seen in radiological assessment, associated with sensorineural hearing impairment or syndromic forms of deafness such as Pendred syndrome (MIM 274600), an autosomal-recessive disorder, is characterized additional with thyroid dysfunction which may leads to goiter. Up to now only mutations in the SLC26A4 gene, located on Chromosome 7q31, have been made responsible for Pendred- and Enlarged Vestibular Aqueduct syndrome.

How to order test | brochure PDF | Resources | Clinical Services Background: Although many of the genetic forms of nonsyndromic hearing loss are difficult to differentiate from one another, PDS is somewhat distinct because all patients with two mutations in this gene have a particular abnormality of the inner ear that can be seen when an MRI or CT scan of the temporal bone is performed. This abnormality is called enlarged vestibular aqueducts (EVA) and may be seen in combination with Mondini dysplasia (a common cavity malformation of the inner ear).
