Audiologic Aspects of the Search for DFNA20: A Gene Causing Late-Onset, Progressive, Sensorineural Hearing Loss

Abstract

The hearing loss demonstrated by this mid-Michigan family is a novel form of nonsyndromic, genetic, late-onset, bilateral, progressive, sensorineural hearing loss. The locus of the gene, the 20th for autosomal dominant hearing loss, is at band 17q25 of chromosome 17.
